The nervous system maintains homeostasis by sending electrochemical signals throughout the body, coordinating and executing both the voluntary and involuntary processes that maintain homeostasis, according to Penn Medicine. The nervous system is comprised of fibrous axons, which stretch throughout the body and interconnect to coordinate activity, states Wikipedia.
The brain is the ultimate control center of all activity in the body and is the organ that is primarily responsible for the maintenance of homeostasis, notes the University of California at Berkeley. The hypothalamus is of particular importance in homeostasis. It controls the pituitary gland, thus regulating the endocrine system, and also exerts great influence over internal organs via the nervous system.
The autonomic nervous system plays a particularly vital role in the maintenance of homeostasis, notes the National Center for Biotechnology Information. The autonomic nervous system regulates involuntary bodily functions, according to Wikipedia.
The nervous system is the most complex system in the body and is comprised of the central nervous system and the peripheral nervous system, states Penn Medicine. The central nervous system is comprised of the brain and the spinal cord, whereas the peripheral nervous system is composed of the nerve extensions beyond those central pathways. Both, when combined, interconnect all of the parts of the body and allow for the processes creating homeostasis to occur.
