The enteric nervous system is sometimes considered part of the autonomic nervous system, and sometimes considered an independent system. The sympathetic and parasympathetic nervous systems have links to important organs. The ANS is classically divided into two subsystems: the parasympathetic nervous system (PSNS) and sympathetic nervous system (SNS). Its divided into the sympathetic and parasympathetic nervous systems. Whereas most of its actions are involuntary, some, such as breathing, work in tandem with the conscious mind. The ANS affects heart rate, digestion, respiratory rate, salivation, perspiration, pupillary dilation, micturition (urination), and sexual arousal. The autonomic nervous system (ANS) is the part of the peripheral nervous system that acts as a control system, functioning largely below the level of consciousness and controlling visceral functions. Association nerves integrate sensory input and motor output these nerves number in the thousands. Nerves in the somatic nervous system control voluntary movement and activity, transmitting information between the CNS and the skeletal muscles and external.They include information related to smell, vision, eyes, eye muscles, the mouth, taste, ears, the neck, shoulders, and the tongue. Cranial nerves are the nerve fibers that carry information into and out of the brain stem.Spinal nerves are peripheral nerves that carry motor commands and sensory information into the spinal cord.The human nervous system: The major organs and nerves of the human nervous system. Okay, lets start with the somatic nervous system, which describes a set of nerve fibers that control voluntary actions and convey sensory information from the. The somatic nervous system consists of three parts: Where the somatic nervous system consists of cranial nerves (12 pairs) and spinal nerves (31 pairs) and is under the volitional control of the individual in.

The somatic nervous system controls all voluntary muscular systems within the body, and also mediates involuntary reflex arcs. The SoNS consists of efferent nerves responsible for stimulating muscle contraction, including all the non-sensory neurons connected with skeletal muscles and skin. The somatic nervous system (SoNS) is the part of the peripheral nervous system associated with the voluntary control of body movements via skeletal muscles. The peripheral nervous system (PNS) is divided into the somatic nervous system and the autonomic nervous system. The peripheral nervous system includes both a voluntary, somatic branch and an involuntary branch that regulates visceral functions.Įxamples of body processes controlled by the ANS include heart rate, digestion, respiratory rate, salivation, perspiration, pupillary dilation, urination, and sexual arousal.
