the glands and the muscles of the internal organs (such as the heart). Its sympathetic division
arouses; its parasympathetic division calms.
visceral reflex arc correct answers receptors, afferent neurons, interneurons, efferent neurons,
effectors
afferent neurons correct answers Nerve cells that carry impulses towards the central nervous
system
efferent neurons correct answers neurons that take information from the brain to the rest of the
body
Which houses motor neurons? correct answers anterior root of spinal nerve
