The autonomic nervous system.

Ans anatomy. Smooth muscle walls of the blood vessels walls of the hollow organs. It operates independently of voluntary control although certain events such as stress fear sexual excitement. Start studying autonomic nervous system.

The autonomic nervous system ans formerly the vegetative nervous system is a division of the peripheral nervous system that supplies smooth muscle and glands and thus influences the function of internal organs. The autonomic nervous system ans is a very complex multifaceted neural network that maintains internal physiologic homeostasis. The peripheral nervous system consists of the somatic nervous system sns and the autonomic nervous system ans.

This set has efferent fibers that go from the ganglia to effector organs see figure. Learn vocabulary terms and more with flashcards games and other study tools. This network includes cardiovascular thermoregulatory gastrointestinal gi genitourinary gu and ophthalmologic pupillary systems see the following image.

The sns consists of motor neurons that stimulate skeletal muscles. Overview the autonomic nervous system ans maintains blood pressure regulates the rate of breathing influences digestion urination and modulates sexual arousal. In contrast the ans consists of motor neurons that control smooth muscles cardiac muscles and glands.

Examples are the heartbeat the digestive functions of the intestines control of respiration and secretion by glands. The preganglionic cell bodies of the sympathetic system are located in the intermediolateral horn of the spinal cord between t1 and l2 or l3. The sympathetic portion of the ans controls reactions like the stress response and the fight or flight reaction.

The autonomic nervous system. The autonomic nervous system is the part of the peripheral nervous system that regulates the basic visceral processes needed for the maintenance of normal bodily functions.
