Plexus of Auerbach

A. Anatomic Aspects of the ANS The motor (efferent) portion of the ANS is the major pathway for information transmission from the central nervous system (CNS) to the involuntary effector tissues (smooth muscle, cardiac muscle, and exocrine glands Figure 6-1). The enteric nervous system (ENS) is a semiautonomous part of the ANS, with specific functions for the control of the gastrointestinal tract. The ENS consists of the myenteric plexus (plexus of Auerbach) and the submucous plexus (plexus of Meissner) and includes inputs from the parasympathetic and sympathetic nervous systems.
