Question
Non-conscious information of this sensory modality is carried via the dorsal and ventral spinocerebellar tracts. For 10 points each:
[10m] Name this sense that relies heavily on muscle spindles and other signals from skeletal muscles. This ability may be tested by joint position reproduction.
ANSWER: proprioception [or kinesthetic sense; or kinesthesia; or word forms of proprioceptive; accept proprioceptors or proprioreceptors; prompt on sense of position; reject “vestibular sense”]
[10h] These organs found in muscle-tendon junctions act as proprioceptors. These structures name the reflex that opposes the stretch reflex, in which muscle tension stimulating these organs causes autoinhibition.
ANSWER: Golgi tendon organ [or Golgi organ; or neurotendinous organ; or neurotendinous spindle; accept Golgi tendon organ reflex]
[10e] Golgi tendon organs consist of a sensory fiber innervating a bundle of fibers of this triple-helical elastic protein. In Golgi tendon organs, this protein’s fibers are less densely packed than in tendons and ligaments.
ANSWER: collagen [accept collagen fibers; accept type I collagen]
