Muscle spindles are stretch receptors within the body of a skeletal muscle that primarily detect changes in the length of the muscle. They convey length information to the central nervous system via afferent nerve fibers. This information can be processed by the brain as proprioception. The responses of muscle spindles to changes in length also play an important role in regulating t… WebThe muscle spindle gets excited when the muscle is stretched. The nerve impulse thus generated is carried by the sensory neuron to the spinal cord. ... Sensory neuron also sends signals to the brain regarding the contraction of muscle. Importance. The main purpose of the stretch reflex is to prevent the tearing of muscle due to stretching. http://humanphysiology.academy/Neurosciences%202415/Chapter%202/P.2.1p%20MS%20details.html black stone in spanish
