The motor (efferent) division carries signals from the central nervous system (the brain and the spinal cord) mainly to gland and muscle cells that carry out the body's responses. Central nervous system. The PNS consists of the nerves and ganglia outside the brain and spinal cord. A division of the nervous system consisting of all nerves that are not part of the brain or spinal cord. The three divisions of nervous system are central nervous system peripheral nervous system and asutonomous nervous system. Relays info between brain and body, pairs of spinal nerves, connected to specific muscles & glands. Even though . The two divisions of the autonomic nervous system are the sympathetic and parasympathetic nervous systems.The correct option is C. sympathetic and parasympathetic nervous systems.. In the human body, the neural system integrates the activities of organs based on the stimuli, which the neurons detect and transmit. This system is composed of a nerve plexus or a meshwork of fibers innervating the digestive tract from the esophagus to the distal colon. The autonomic system is responsible for regulating involuntary body functions. Spinal cord. 2 main divisions of the nervous system Central Nervous System Brain Spinal Cord Peripheral Nervous System: Autonomic Nervous System Somatic Nervous System Central Nervous System The control center of the body. It also controls other body systems and processes, such as digestion , breathing and sexual development (puberty) . The nervous system has two principle divisions for function and two principle divisions for structure. The nervous system is often divided into components called gray matter and white matter. The two functional subdivisions of the PNS are the afferent (sensory) division and the efferent (motor) division. The nervous system transmits signals between the brain and the rest of the body, including internal organs. Neuron A nerve cell that is specialized to receive and conduct electrical impulses Autonomic Nervous System Part of the nervous system that carries UNCONSCIOUS motor and sensory informaiton Somatic Nervous System 1. Wiki User. Name the two main organs of our central nervous system. Terms in this set (8) Central 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. Divisions of the Nervous System: It is broadly divided into two parts; the central nervous system (CNS) and the peripheral nervous system (PNS). This article is going to examine the parasympathetic nervous system, one of two majors divisions of the larger autonomic system. The Nervous System Your nervous system is your body's command center.

The CNS performs integrative and control functions. Autonomic Nervous . The nerves connect to the central nervous system via 12 pairs of cranial nerves and 31 pairs of spinal nerves. Parasympathetic division - The part of the autonomic nervous system originating in the brain stem and the lower part of the spinal cord that, in general, inhibits or opposes the physiological effects of the sympathetic nervous system, as in tending to stimulate digestive secretions, slow the heart, constrict the pupils, and dilate blood vessels. The sympathetic system is associated with the fight-or-flight response, and parasympathetic activity is referred to by the epithet of rest and digest. The peripheral nervous system ( PNS) contains neurons outside of the brain and spinal cord and consists of the somatic nervous system ( SNS ), the autonomic nervous system ( ANS ), and the enteric nervous system ( ENS ). Homeostasis is the balance between the two systems. Each subdivision has structural and functional characteristics that distinguish it from the others. The central nervous system is contained within the brain and spinal cord.

Human nervous system is mainly divided into 3 divisions, which are as follows: 1. The peripheral nervous system is made up of nerves and small amount of gray matter known as the ganglia. The peripheral nervous system is subdivided into the somatic nervous system and the autonomic nervous system. It also receives commands from the CNS telling our muscles to move (resulting in running, walking etc.) The parasympathetic nervous system is divided into cranial and sacral outflows.
