The autonomic nervous system (ANS), formerly the vegetative nervous system, is a division of the peripheral nervous system that supplies smooth muscle and glands, and thus influences the function of internal organs. 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.

The autonomic nervous system allows the higher brain centers (the cerebral cortex and the limbic system) to subconsciously control organs of the autonomic nervous system. It controls functions such as sexual arousal, urination, digestion, and cardiorespiratory functions. Image: Diagram showing the divisions of the nervous system. License: CC BY-SA . Autonomic nervous system divisions. The autonomic nervous system has 2 divisions based on anatomical, functional, and to a considerable extent, pharmacological grounds: the sympathetic and parasympathetic divisions.

The autonomic nervous system (ANS), formerly the vegetative nervous system, is a division of the peripheral nervous system that supplies smooth muscle and glands, and thus influences the function of internal organs. 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. This system is the primary mechanism in control of the fight-or-flight response. Within the brain, the autonomic nervous system is regulated by the hypothalamus.

The autonomic nervous system. The symptoms of lesion. The autonomic nervous system is a part of nervous system that regulates the activity of internal organs, glands, blood and lymphatic vessels, smooth and striated muscles and organs of sensation. The autonomic nervous system is a purely efferent system of nerve fibers with ganglia and plexuses outside the central nervous system innervating the blood vessels, heart, viscera, glands, and smooth muscles throughout the body.

parasympathetic ganglion: The autonomic ganglia of the parasympathetic nervous system. Most are small terminal ganglia or intramural ganglia, so named because they lie near or within (respectively) the organs they innervate. Autonomic ganglia are clusters of neuronal cell bodies and their dendrites. Unlike the majority of neurons found in the central nervous system, an action potential in a dorsal root ganglion neuron may initiate in the distal process in the periphery, bypass the cell body, and continue to propagate along the proximal process until reaching the synaptic terminal in the dorsal horn of the spinal cord.

Autonomic ganglia are widely used as models for studying the establishment and plasticity of neurochemical organization in the autonomic nervous system. They contain well-defined and rather homogenous neuron populations which express a variety of neurotransmitters and neuromodulators (. classical transmitters and neuropeptides in different combinations). Above all, PGNs may be maintained in vitro to investigate effects of neurotrophic factors, cytokines and genetic manipulations on transmitter and neuropeptide expression.

The autonomic system usually is defined as a motor system that innervates three major types of tissue: cardiac muscle, smooth muscle, and glands. However, it also relays visceral sensory information to the central nervous system and processes it so that alterations can be made in the activity.

The autonomic system usually is defined as a motor system that innervates three major types of tissue: cardiac muscle, smooth muscle, and glands.

The autonomic nervous system (ANS), formerly the vegetative nervous system, is a division of the peripheral nervous system that supplies . The PNS consists of the nerves and ganglia outside the brain and spinal cord. The main function of the PNS is to connect the CNS to the limbs and organs, essentially serving as a relay between the brain and spinal cord and the rest of the body.

Autonomic ganglia are the sites of synaptic transmission in the peripheral nervous system. They are widely believed to function only as relay stations in the efferent pathways which control the vasculature and viscera. Autonomic Ganglia, the sixth volume of the Autonomic Nervous System book series, aims to challenge this view by reviewing aspects of our current understanding of the structure and integrative functions of ganglionic neurones and their connections. Recent research has concentrated on the membrane biophysics of synaptic transmission, the specification of functional pathways, connectivity with other central and peripheral neurones, the distribution and role of neuropeptides and the long and short-term modulation of autonomic signalling.
