WebThe Structure of Reflexes. One difference between a somatic reflex, such as the withdrawal reflex, and a visceral reflex, which is an autonomic reflex, is in the efferent branch. The output of a somatic reflex is the lower motor neuron in the ventral horn of the spinal cord that projects directly to a skeletal muscle to cause its contraction. WebAll reflex actions follow an overall sequence through the nervous system which is called the reflex arc. Crucially this does not involve the conscious part of the brain, which makes it …

WebThere are five steps in a knee-jerk reflex arc as follows: A tap on the patellar tendon (tendon attached to the kneecap) is sensed by stretch receptors in the muscle (muscle spindles). The muscle spindle produces a pattern of nerve impulses that are conveyed along a sensory (afferent) nerve fiber, past its cell body in the dorsal root ganglion ... Web2) Sensory neuron—conducts the afferent impulses to the CNS. 3) Integration center—consists of one or more synapses in the CNS. 4) Motor neuron—conducts the efferent impulses from the integration center to an effector. 5) Effector—muscle fibers or glands that respond to the efferent impulses by contracting or secreting a product.
