enteric nervous system ppt
The enteric nervous system (ENS) is part of the peripheral nervous system that is embedded in the walls of the gastrointestinal tract. It contains two plexuses - the myenteric plexus between the outer longitudinal and inner circular muscle layers that controls gastrointestinal movements, and the submucosal plexus between the inner circular muscle layer and gastrointestinal lining that controls local functions like secretion and absorption. The ENS contains millions of neurons, glial cells, and can function independently through sensory neurons, interneurons, and motor neurons using excitatory and inhibitory neurotransmitters, though it normally communicates with the central nervous system via the parasympathetic and sympathetic nervous systems. Damage to ENS neurons or pathways may lead to slow recovery due
