The nervous system is also responsible for regulating the core temperature of the body. Organisms that possess a nervous system are capable of much more complex behaviour than are organisms that do not. 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. The nervous system includes the central and peripheral nervous systems. How Do You Apply for Social Security Benefits? The human nervous system is far more complex than a simple reflex arc, although the same stages still apply. The autonomic nervous system is a complex set of neurons that mediate internal homeostasis without conscious intervention or voluntary control. The Endocrine System. It functions from the tiny level of individual cells to affecting the whole body at once. Chapter 16. How Does the Nervous System Maintain Homeostasis. The nervous system monitors and controls almost every organ system through a series of positive and negative feedback loops.The Central Nervous System (CNS) includes the brain and spinal cord. Biologydictionary.net Editors. It is, however, constantly active at a basic level to maintain homeostasis. Peripheral nervous system nerves often extend a great length from the central nervous system to reach the periphery of the body. The sympathetic nervous system (SNS) controls the body's responses to a perceived threat and is responsible for the "fight or flight" response.. Receptors inside and outside the body are constantly monitoring conditions and watching for changes. The sympathetic nervous system's primary process is to stimulate the body's fight or flight response. Separate pages describe the nervous system in general, sensation, control of skeletal muscle and control of internal organs.. After a crisis or danger has passed, the system helps to calm the body by slowing heart and breathing rates, resuming digestion, contracting the pupils, and stopping sweating. This tissue is populated with millions of photoreceptor cells, ganglion cells, and bipolar cells. The sense organs, including the eye, contain receptors that are sensitive to stimuli and respond with reflex actions.
