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. The output of a visceral reflex is a two-step pathway starting with the preganglionic fiber emerging from a lateral horn neuron in the spinal cord, or a cranial nucleus neuron in the brain stem, to a ganglion—followed by the postganglionic fiber projecting to a target effector. The other part of a reflex, the afferent branch, is often the same between the two systems.
Adding the prefix “ef-” suggests the meaning “to carry away,” whereas adding the prefix “af-” suggests “to carry toward or inward.”

need help on question 2 please and thank you A reflex arc is the pathway that receives sensory information about a change in some body parameter, integrates the information and then carries out a response via the endocrine and/or nervous system. Today, we will be investigating specific reflexes, where the stimulus will be conveyed by a sensory neuron and the response will be carried through a motor neuron. 1. DIAGRAM THE REFLEX ARC: INCLUDE ALL THE NECESSARY COMPONENTS 2. Finish...

A stretch reflex begins with which branch of the nervous system. What is the integrating centre for the knee jerk? What is the approximate vibratory stimulus in Hertz required for a tonic vibration reflex? What division of the efferent nervous system controls contraction of gastrointestinal muscle? What sort of neurons arc involved in polysynaptic reflexes that are not involved in monosynaptic reflexes? The efferent output from the knee jerk targets what muscles and how do they respond? Would you expect...
