Proprioception Wikipedia. The cerebellum is largely responsible for coordinating the unconscious aspects of proprioception. Proprioception 12PRO pree o SEP shn, from Latinproprius, meaning ones own, individual, and capio, capere, to take or grasp, is the sense of the relative position of ones own parts of the body and strength of effort being employed in movement. In humans, it is provided by proprioceptors muscle spindles in skeletal striated muscles and tendons Golgi tendon organ and the fibrous capsules in joints. It is distinguished from exteroception, by which one perceives the outside world, and interoception, by which one perceives pain, hunger, etc., and the movement of internal organs. The brain integrates information from proprioception and from the vestibular system into its overall sense of body position, movement, and acceleration. Rogue is a fictional superhero appearing in American comic books published by Marvel Comics, commonly in association with the XMen. The character debuted in Avengers. Proprioception p r o p r i o s p n, p r i PROpreeoSEPshn, from Latin proprius, meaning ones own, individual, and capio, capere. A Dreadnought is a cybernetic combat walker of intermediate size used by the Chapters of the. The word kinesthesia or kinsthesia kinesthetic sense strictly means movement sense, but has been used inconsistently to refer either to proprioception alone or to the brains integration of proprioceptive and vestibular inputs. Proprioception has also been described in other animals such as vertebrates, and in some invertebrates such as arthropods. More recently proprioception has also been described in flowering land plants angiosperms. History of studyeditThe position movement sensation was originally described in 1. Julius Caesar Scaliger as a sense of locomotion. Much later, in 1. Charles Bell expounded the idea of a muscle sense,8 which is credited as one of the first descriptions of physiologic feedback mechanisms. Bells idea was that commands are carried from the brain to the muscles, and that reports on the muscles condition would be sent in the reverse direction. In 1. 84. 7 the London neurologist Robert Todd highlighted important differences in the anterolateral and posterior columns of the spinal cord, and suggested that the latter were involved in the coordination of movement and balance. At around the same time, Moritz Heinrich Romberg, a Berlin neurologist, was describing unsteadiness made worse by eye closure or darkness, now known as the eponymous Rombergs sign, once synonymous with tabes dorsalis, that became recognised as common to all proprioceptive disorders of the legs. Later, in 1. 88. 0, Henry Charlton Bastian suggested kinaesthesia instead of muscle sense on the basis that some of the afferent information back to the brain comes from other structures, including tendons, joints, and skin. In 1. 88. 9, Alfred Goldscheider suggested a classification of kinaesthesia into three types muscle, tendon, and articular sensitivity. In 1. 90. 6, Charles Scott Sherrington published a landmark work that introduced the terms proprioception, interoception, and exteroception. The exteroceptors are the organs that provide information originating outside the body, such as the eyes, ears, mouth, and skin. Tabtight professional, free when you need it, VPN service.

Powers Exercise Physiology 7Th Edition' title='Powers Exercise Physiology 7Th Edition' />The interoceptors provide information about the internal organs, and the proprioceptors provide information about movement derived from muscular, tendon, and articular sources. Using Sherringtons system, physiologists and anatomists search for specialised nerve endings that transmit mechanical data on joint capsule, tendon and muscle tension such as Golgi tendon organs and muscle spindles, which play a large role in proprioception. Primary endings of muscle spindles respond to the size of a muscle length change and its speed and contribute both to the sense of limb position and movement. Secondary endings of muscle spindles detect changes in muscle length, and thus supply information regarding only the sense of position. Essentially, muscle spindles are stretch receptors. It has been accepted that cutaneous receptors also contribute directly to proprioception by providing accurate perceptual information about joint position and movement, and this knowledge is combined with information from the muscle spindles. ComponentseditA major component of proprioception is joint position sense, which is determined by measuring the accuracy of jointangle replication. Clinical aspects of joint position sense are measured in joint position matching tests that measure a subjects ability to detect an externally imposed passive movement, or the ability to reposition a joint to a predetermined position. These involve an individuals ability to perceive the position of a joint without the aid of vision. Often it is assumed that the ability of one of these aspects will be related to another however, experimental evidence suggests there is no strong relation between these two aspects. This suggests that while these components may well be related in a cognitive manner, they may in fact be physiologically separate. More recent work into the mechanism of ankle sprains suggests that the role of reflexes may be more limited due to their long latencies even at the spinal cord level, as ankle sprain events occur in perhaps 1. In accordance, a model has been proposed to include a feedforward component of proprioception, whereby the subject will also have central information about the bodys position before attaining it. Kinesthesia is a key component in muscle memory and hand eye coordination, and training can improve this sense see blind contour drawing. The ability to swing a golf club or to catch a ball requires a finely tuned sense of the position of the joints. This sense needs to become automatic through training to enable a person to concentrate on other aspects of performance, such as maintaining motivation or seeing where other people are. Basis of proprioceptive senseeditThe initiation of proprioception is the activation of a proprioreceptor in the periphery. The proprioceptive sense is believed to be composed of information from sensory neurons located in the inner ear motion and orientation and in the stretch receptors located in the muscles and the joint supporting ligaments stance. There are specific nerve receptors for this form of perception termed proprioreceptors, just as there are specific receptors for pressure, light, temperature, sound, and other sensory experiences. Proprioreceptors are sometimes known as adequate stimuli receptors. TRPN, a member of the transient receptor potential family of ion channels, has been found to be responsible for proprioception in fruit flies,1. African clawed frogs,2. Piezo. 2, a nonselective cation channel, has been shown to underlie the mechanosensitivity of proprioceptors in mice. The channel mediating human proprioceptive mechanosensation has yet to be discovered. Proprioception of the head stems from the muscles innervated by the trigeminal nerve, where the GSA fibers pass without synapsing in the Gasserian ganglion first order sensory neuron, reaching the mesencephalic tract and the mesencephalic nucleus of trigeminal nerve. Although it was known that finger kinesthesia relies on skin sensation, recent research has found that kinesthesia based haptic perception relies strongly on the forces experienced during touch. This research allows the creation of virtual, illusory haptic shapes with different perceived qualities. Rogue comics Wikipedia. Rogue is a fictional superhero appearing in American comic books published by Marvel Comics, commonly in association with the X Men. The character debuted in Avengers Annual 1. November 1. 98. 1 as a villain, but then soon after she joined the X Men. Rogue is part of a subspecies of humans called mutants, who are born with superhuman abilities. Rogue has the involuntary ability to absorb and sometimes also remove the memories, physical strength, and superpowers of anyone she touches. Therefore, Rogue considers her powers to be a curse. For most of her life, she limited her physical contact with others, including her on off love interest, Gambit. However, after many years, Rogue finally gained full control over her mutant ability. Hailing from the fictional Caldecott County, Mississippi, Rogue is the X Mens self described southern belle. Intel Corporation 82915G. A runaway, she was adopted by Mystique of the Brotherhood of Evil Mutants and grew up as a villain. Eaton Panelmate Software on this page. After Rogue permanently absorbs Ms. Marvels psyche and Kree powers, she reforms and turns to the X Men, fearing for her sanity. Rogues real name and early history were not revealed until nearly 2. Until the back story provided by Robert Rodi in the ongoing Rogue series, which began in September 2. Rogues background was only hinted at. Her name was revealed as Anna Marie, although her surname is still unknown. She has sometimes adopted the name Raven, which is the first name of her foster mother, Mystique. Rogue has been one of the most prominent members of the X Men since the 1. She was 5 on IGNs Top 2. X Men list for 2. Top Ten X Babes list for 2. Marvels list of Top 1. Toughest Females for 2. X Man on CBRs Top 5. X Men of All Time for 2. She was ranked tenth in Comics Buyers Guides 1. Sexiest Women in Comics list. Rogue has been featured in most of the X Men animated series, and various video games. In the X Men film series, she is portrayed by Anna Paquin. Her visual cue is often the white streak that runs through her hair. Publication historyeditRogue was first slated to appear in Ms. Marvel 2. 5 1. 97. How Many Cups In A Bag Of Oyster Crackers'>How Many Cups In A Bag Of Oyster Crackers. Marvel Super Heroes 1. Rogues first published appearance was in Avengers Annual 1. She made her first X Book appearance in Uncanny X Men 1. X Men in Uncanny X Men 1. Rogue has also had two miniseries and one ongoing title. Rogues real name and early history were not revealed until more than 2. Until the back story provided by Robert Rodi in the ongoing Rogue series, begun in September 2. This resulted in Rodis version of Rogues origins inadvertently conflicting with earlier information. In X Men Unlimited 4, Scott Lobdell indicates that Rogue ran away from her father after her mutant powers manifested, but in Uncanny X Men 1. Rogue reflects that she never knew her father because hed left before she was born, and several issues, including Uncanny X Men 1. X Men 9. 3, indicate that Rogue was taken in by Mystique and Destiny before her mutation became active. Rogue is a regular character in Uncanny Avengers 2. Fictional character biographyeditEarly lifeeditHer parents, Owen and Priscilla, married early in their relationship and lived in a back to nature hippie commune in Caldecott County, Mississippi. Born as Anna Marie, she also enjoyed the attentions of her Aunt Carrie, on her mothers side. Anna Marie was raised speaking colloquial. English and French, common to the Mississippi bayou area. The communes failed attempt to use Native American mysticism to reach the Far Banks resulted in Priscillas disappearance. Carrie took over Annas care, and in her grief at the loss of her sister, was a strict and authoritarian guardian. Anna Marie was a rebellious child8 and, at some point, the exact event or reasons still unclear, she ran away from home as a young teenager. At some point, Rogue grew close to a boy named Cody Robbins. During their flirtation, Cody impulsively kissed her, at which point her latent mutant power to absorb the life energy and psyche of others with skin to skin contact emerged. Rogue was traumatized by the experience, and Cody was left in a permanent coma. Hence, Rogue wore body concealing clothing that eliminated the possibility of accidental skin contact. She wished she did not have to cover up so much around folks to protect them from her. She thought her power was a curse. Not long after, she was approached by Mystique, who sought her out on the advice of her precognitive partner Destiny. Mystique ultimately takes Rogue in as a daughter. In time, however, Mystique turned Rogues loneliness, envy, bitterness, and despair into anger, thus recruiting her into the Brotherhood of Mutants. Chris Claremont said in June 2. Marvel in 1. 99. 1, Mystique would have been Rogues real mother. It is a story line that appeared in a 2. X Men Forever. 1. Brotherhood of Evil MutantseditAfter Rogues mutation emerges, Mystique begins coaxing Rogue into taking part in her terrorist activities as a member of the Brotherhood of Mutants. Rogue initially wants only a normal life, but after she kisses a boy named Cody, unintentionally rendering him unconscious with her power, she gives up on normality and begins taking part in Mystiques plans. Rogue and Mystique associate briefly with a mutant named Blindspot, whose power to erase the memories of others by touch somehow counteracts Rogues mutation enough to allow them to make physical contact safely. Blindspot and Rogue become good friends, but when Mystique decides to sever professional ties with Blindspot, Blindspot erases all memory of her from both Mystique and Rogue. When Mystique debuts her Brotherhood of Evil Mutants, Destiny advises her to keep Rogue out of the action, advice which proves important when several members of the new Brotherhood are arrested and imprisoned. Mystique concocts a plan to free the other members of the Brotherhood by having Rogue absorb Ms. Marvels formidable powers. Rogue attacks Ms. Marvel on her front doorstep as she is returning home from grocery shopping. Due to Ms. Marvels formidable persona, Rogues struggle to absorb her powers is prolonged, and the transfer of Ms. Marvels psyche and powers is permanent. Rogue then throws her off the Golden Gate Bridge. She battles the Avengers using her newly acquired powers. While at the Pentagon, she literally bumps into Carol Danvers, leading into a fight with Storm and Wolverine of the X Men. Though Rogue proves more than a match for them, the three of them escape the Pentagon. Later, with Mystique and Destiny, Rogue attacks Angel and Dazzler, but is overpowered by Dazzler. Rogue develops a grudge against Dazzler for her controllable mutation and her relationship with Angel of the X Men. Rogue is defeated by Dazzler a few times before Dazzler is publicly revealed to be a mutant and goes into hiding. Sometime after this, Rogue, Mystique and Destiny encountered the half human, half Dire Wraith entity called Hybrid, with whom the three formed an alliance with against the Spaceknight, Rom. However, when Rogue seized an opportunity to use her power on him, she experienced both his loneliness and his nobility. This moment had a profound effect on her and served as a crucial turning point in her life. The more Rogue uses her mutant power, the more her mind becomes filled with fragmentary psychic echoes of the people she absorbs.
