Question

Quizplus · Accepted Answer

Annulospiral endings are specialized sensory receptors located in muscle spindles, which are embedded within the extrafusal fibers of skeletal muscle. The annulospiral endings detect changes in muscle length and are associated with the nuclear bag fibers, which are one of the two types of specialized muscle fibers within the muscle spindle. The other type of specialized muscle fiber within the muscle spindle is the nuclear chain fiber. Mossy fibers are a type of sensory nerve fibers that transmit proprioceptive information from muscle spindles and other sensory receptors to the central nervous system. Basal nuclei are clusters of neurons located deep within the cerebral hemispheres that are involved in the control of movement and a variety of other functions. So, the correct answer is A) the nuclear bag fibers.
