Engages the muscle spindle
WebJan 7, 2024 · Almost every muscle contains muscle spindles. These delicate sensory receptors inform the central nervous system (CNS) about changes in the length of individual muscles and the speed of stretching. With this information, the CNS computes the position and movement of our extremities in space, which is a requirement for motor control, for … WebFeb 1, 2024 · The monosynaptic patellar reflex. A tap to the patellar tendon stretches the quadriceps muscle (1) resulting in activation of the muscle spindle (2). The afferent neuron of the muscle spindle, detecting stretch, sends a signal to the spinal cord (3) and synapses directly with a motor neuron (4) that causes the quadriceps muscle to contract (5).
