Parasympathetic fibres arise from S2,S3,S4. Carry preganglionic parasympathetic and visceral afferent fibres from pelvic and genital organs.
The component of the ANS that is characterized by ganglion located in or near effector organs is called the parasympathetic nervous system. The ganglia of the parasympathetic nervous system are located close to or within the target organs they innervate, allowing for direct and localized control of bodily functions. This branch of the autonomic nervous system is responsible for promoting rest, digestion, and relaxation.
The parasympathetic nervous system.
Organs that do not receive parasympathetic input include the adrenal medulla, sweat glands, and most blood vessels. These structures are mainly innervated by the sympathetic nervous system.
Dual innervation refers to an organ receiving input from both the sympathetic and parasympathetic divisions of the autonomic nervous system. This allows for precise regulation of the organ's function by balancing the effects of these two opposing systems. Examples include the heart receiving both sympathetic stimulation (increasing heart rate) and parasympathetic stimulation (slowing heart rate).
The autonomic ganglia of the parasympathetic system are called terminal ganglia or intramural ganglia. They are located near or within the target organs, allowing for more localized and specific control of parasympathetic functions.
The pelvic splanchnic nerve contains parasympathetic fibers that regulate the function of pelvic organs, such as the bladder, rectum, and reproductive organs. These fibers are involved in controlling processes like urination, defecation, and sexual function.
