Examples are the heartbeat the digestive functions of the intestines control of respiration and secretion by glands.

Anatomy of ans. The sympathetic nervous system sns descends to the intermediolateral and intermediomedial cells in the thoracolumbar regions of the spine extending from ti to l2. Smooth muscle walls of the blood vessels walls of the hollow organs.

The autonomic nervous system ans is the part of the nervous system that regulates involuntary functions. The autonomic nervous system ans consists of the sympathetic and parasympathetic nervous system. In contrast the ans consists of motor neurons that control smooth muscles cardiac muscles and glands.

The sns consists of motor neurons that stimulate skeletal muscles. The autonomic nervous system. The craniosacral part parasympathetic and the thoracolumbar part sympathetic.

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 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.
