The sympathetic nervous system mobilizes energy and resources during times of stress and arousal, while the parasympathetic nervous system conserves energy and resources during relaxed states, including sleep.

The autonomic nervous system is made of neurons connecting the CNS with internal organs. Somatic nerves in the cervical region are related to the neck and arms those in the thoracic region serve the chest and those in the lumbar and sacral regions interact with the legs. Sympathetic control activities that increase energy expenditures. Somatic-nervous-system definition Meanings The part of the peripheral nervous system that transmits signals from central nervous system to skeletal muscles, and from receptors of external stimuli thereby mediating sight, hearing and touch. Autonomic Nervous System controls involuntary muscles, such as smooth and cardiac muscle. Somatic Nervous System controls skeletal muscle as well as external sensory organs. A: The human eye is one of the five sense organs present in the human body and is responsible for the p. Motor Nervous System carries information from the CNS to organs, muscles, and glands. Q: answer briefly Knowing how eye works, if a person cannot see certain colors, can they also cant see. The somatic nervous system is made up of neurons connecting the CNS with the parts of the body that interact with the outside world. Solution for Define peripheral nervous system. The brain sends messages via the spinal cord to peripheral nerves throughout the body that serve to control the muscles and internal organs.

Overall the nervous system is a vast biological computing device formed by a network of gray matter regions interconnected by white matter tracts. The other great division of the human brain is the peripheral nervous system (PNS), which consists of nerves and small concentrations of gray matter called ganglia, a term specifically used to describe structures in the PNS. The brain is protected by the skull, while the spinal cord, which is about 17 inches (43 cm) long, is protected by the vertebral column. The involuntary nervous system (vegetative or autonomic nervous system) regulates the processes in the body that we cannot consciously influence. The forebrain, midbrain, hindbrain, and spinal cord form the central nervous system (CNS), which is one of two great divisions of the nervous system as a whole. The voluntary nervous system (somatic nervous system) controls all the things that we are aware of and can consciously influence, such as moving our arms, legs and other parts of the body. The autonomic nervous system (ANS), which includes the sympathetic nervous system (SNS), the parasympathetic nervous system (PSNS), and the enteric nervous system (ENS), is triggered into action.
