Document Summary
Outline the anatomical composition of the autonomic nervous system. Compare the sympathetic and parasympathetic divisions of the autonomic nervous system for similarities and differences. Explain the physiological and clinical significance of these receptors. Discuss the relationship of adrenal glands to the sympathetic nervous system. Communication link by which cns controls activities of muscles and glands. Body prepares itself for a fight or flight. Unnecessary functions are reduced and energy is diverted to other functions vital to survival. Innervates cardiac muscle, smooth muscle, most exocrine glands, some endocrine glands, and adipose tissue. Innervates skeletal muscle efferent division of the peripheral nervous system. Page 239 preganglionic neurotransmitters postganglionic neurotransmitters receptors in ganglion (cell bodies) in effector (cell) organs. Cholinergic neurons release acetylcholine all sympathetic and parasympathetic preganglionic neurons all parasympathetic postganglionic neurons sympathetic postganglionic neurons that innervate most sweat glands. Adrenergic neurons release norepinephrine sympathetic postganglionic neurons. * nicotinic receptors are cell bodies of sympathetic and parasympathetic postganglionic neurons.
