The network of thread-like nerves that make up the brain, spinal cord and that run throughout the rest of the body. The nervous system controls the activities of the body, and produces thought, emotions and sensations. The nerves send information from the brain (the body's control centre) to the rest of the body â€“ instructing action such as movement. In return, the senses (e.g., sight, touch) send information back to the brain. In this way, the body is able to move within, and react to, its surroundings.
A coordinating system that regulate internal body functions and responses to external stimuli; in vertebrates it consists of the brain, spinal cord, nerves, ganglia and parts of receptors and effector organs. This system transmits messages throughout the body through electrical signals.
The system in the body consisting of the brain and spinal cord (central nervous system), along with other structures

n. An organized group of cells specialized for the conduction of an electrochemical signal from a receptor through a network to the site at which the response occurs.
The system of nerves, ganglia and (in vertebrates) the spinal cord and brain. It regulates and coordinates all the body's activities.
the peripheral nervous system and central nervous system. The peripheral nervous system includes a network of nerves throughout the body, handling everything from regulating the heart rate to flexing the hand or foot. It also receives information, much of which is sent to the brain. This information is analyzed and coordinated by the central nervous system. The central nervous system is made up of the spinal cord and brain.
The nervous system consists of cells and fibres. The fibres are long processes extending from the nerve cells. The brain and spinal cord are often referred to as the central nervous system. The nerves which lead from the brain and spinal cord to the outlying parts of the body make up the peripheral nervous system; those which carry impulses to and from blood vessels, glands and organ make up the autonomic nervous system. (See also Sympathetic Nervous System)
the part of the body that carries messages to the brain. The nervous system consists of the brain, neural paths, and nerve endings.

all nerve cells and tissues of an organism that control responses to stimuli, coordinates behavior and consciousness
An intricate network of structures that runs extensively throughout the body and activates, coordinates and controls all functions of the body. The nervous system consists of two parts, the central nervous system and the peripheral nervous system. The central nervous system is composed of the brain and the spinal cord. The peripheral nervous system includes the cranial nerves and spinal nerves. Afferent fibers carry sensory impulses to the central nervous system. Efferent fibers carry motor impulses in the form of electrical energy from the central nervous system to the muscles and other organs. Somatic fibers are those associated with the bones, muscles and the skin. Visceral fibers are those associated with the internal organs, blood vessels and mucus membrane. All of the functions are coordinated by a network of tiny structures including neurons, axons, dendrites and ganglia.
System that coordinates all the conscious and subconscious activities of the body. Organs include the brain, spinal cord, and nerves.
The vast network of nerve cells which carries information to and from all parts of the body in order to bring about bodily activity. It is classically divided into the brain, spine and peripheral nervous system.

The nervous system works as a control center for the body. The nervous system is comprised of the voluntary and the involuntary nervous systems, which contain brain, spinal cord, motor and sensory nerves. The sensory nerves provide messages from the brain to the body, and the motor nerves provide messages from the brain to the muscles.
The system of cells, tissues and organs that regulates the body's responses to internal and external stimuli. In vertebrae it consists of the brain, spinal cord, nerves, ganglia and parts of the receptor and effector organs.
The body's complex message system is made up of the CNS, the peripheral nerves (e.g.: those leading from the CNS to the limbs) and the autonomic nerves (which control the heart beat, blood pressure and other functions not under conscious control)
the brain, nervous tissue in the spine and nerves that carry sensation throughout the body
The term "nervous system" may sound like it’s associated with being jumpy and nervous, but that’s not what it means. An organism’s nervous system is the bundle of nerves, receptors, and stimuli that multi-celled animals use to manage their activities - receive messages from various stimuli (electrical, chemical, mechanical, or heat- or cold-related) and translate them into commands for various organs to respond. When you touch a hot stove top and say "Ouch!" while pulling your hand quickly away, that’s your nervous system at work.

The nervous system is the vast network of cells specialized to carry information (in the form of nerve impulses) to and from all parts of the body in order to bring about bodily activity. In vertebrates, the brain and spinal cord together form the central nervous system; the remaining nervous tissue is known as the peripheral nervous system and includes the autonomic nervous system, which is itself divided into the sympathetic and parasympathetic nervous systems. The basic functional unit of the nervous system is the neuron (nerve cell).

Neurons (S) Nervous tissue (S) The nervous system of C. elegans is formed from 302 neurons, each of which has unique properties, morphologies and connectivities. While C. elegans does not have a "brain" per se, most of the nervous system is situated in the head region which is where most of the sensing by the animal occurs. For more details see Hobert, 2005. See Nerve ring
The nervous system is the body tissue that records and distributes information in the body using electrical and chemical transmission. It has two parts. The "central" nervous system is comprised of the brain and spinal cord. The "peripheral" nervous system is the nerve tissue that transmits sensation and motor information back and forth from the body to the central nervous system.
The body system for communication and control.
The nervous system of an animal coordinates the activity of the muscles, monitors the organs, constructs and also stops input from the senses, and initiates actions. Prominent participants in a nervous system include neurons and nerves, which play roles in such coordination. All parts of nervous system are made of nervous tissue.
