Quizplus · Accepted Answer

Muscle spindles are sensory receptors within the belly of a muscle that primarily detect changes in the length of the muscle. They convey length information to the central nervous system via sensory neurons. This information can then be used to adjust the contraction of muscles by activating motor neurons, including both alpha motor neurons (which innervate extrafusal muscle fibers, causing the muscle to contract) and gamma motor neurons (which innervate intrafusal muscle fibers of the spindle itself, adjusting the sensitivity of the spindle). This dual activation helps maintain muscle tone and supports coordinated movements.
