Parasympathetic Nervous System: Definition, Function & Effects The Autonomic Nervous System. The autonomic nervous system, or ANS, is the portion of the nervous system that regulates involuntary processes. In other words, these are processes that are not under conscious control. The ANS is divided into two divisions: the parasympathetic and the sympathetic nervous systems.The sympathetic nervous system, also called 'fight-or-flight' activation, is the segment that prepares the body for emergency situations.ince this is the normal state of the body, the parasympathetic system is more active than the sympathetic system in controlling bodily functions. Neurons in the parasympathetic nervous system utilize acetylcholine, a neurotransmitter for cell-to-cell communication.

- KidsHealth > For Kids > Word! Nervous System. The nervous system controls everything you do, including breathing, walking, thinking, and feeling. This system is made up of your brain, spinal cord, and all the nerves of your body. The brain is the control center and the spinal cord is the major highway to and from the brain. The nerves carry the messages to and from the body, so the brain can interpret them and take action.

Autonomic Nervous System - Anatomy & Physiology The autonomic nervous system is made up of the Sympathetic Nervous System (SNS) and the Parasympathetic Nervous System (PNS). The SNS is activated during critical situations, such as fight or flight responses whilst the PNS is activated whilst at rest, such as during food digestion after eating.

Autonomic nervous system The autonomic nervous system is a control system that acts largely unconsciously and regulates bodily functions such as the heart rate, digestion, respiratory rate, pupillary response, urination, and sexual arousal.he activity of autonomic ganglionic neurons is modulated by “preganglionic neurons” located in the central nervous system. Preganglionic sympathetic neurons are located in the spinal cord, at the thorax and upper lumbar levels.

Sympathetic nervous system The sympathetic nervous system is one of the two main divisions of the autonomic nervous system, the other being the parasympathetic nervous system. The autonomic nervous system functions to regulate the body's unconscious actions.he first cell (the presynaptic cell) sends a neurotransmitter across the synaptic cleft where it activates the second cell (the postsynaptic cell). The message is then carried to the final destination. Presynaptic nerves' axons terminate in either the paravertebral ganglia or prevertebral ganglia.
