Explain how to utilize a Taylor hammer. Be proficient with the review questions and practice tests . Read through this exercise and complete any activities that appear in the readings. Some of the simplest nerve pathways consists of little more than two neurons that communicate across a single synapse . Reflexes are rapid, involuntary responses to stimuli which are mediated over simple nerve pathways called reflex arcs .
Involuntary reflexes are very fast, traveling in milliseconds.
The fastest impulses can reach 320 miles per hour. The receptor at the end of a sensory neuron reacts to a stimulus. A motor neuron conducts a nerve impulse along an efferent pathway from the integration center to an effector. Reflexes can be categorized as either autonomic or somatic. Autonomic reflexes are not subject to conscious control, are mediated by the autonomic division of the nervous system, and usually involve the activation of smooth muscle, cardiac muscle, and glands.
