Nervous system the organ system that along with the endocrine system correlates the adjustments and reactions of an organism to internal and environmental conditions.

. It supports a variety of functions including emotion behavior long-term memory and olfaction. This property enables many important functions of the nervous system such as regulation of vital body functions heartbeat breathing digestion sensation and body movements. This is primarily conducted through electrochemical signaling between nerves and other cells. The complexity of the nervous system increases as we move towards higher animals.

What is the Nervous System. This system is made up of your brain spinal cord and all the nerves of your body. The nervous system is split into two parts. A nervous system can be defined as an organized group of cells called neurons specialized for the conduction of an impulsean excited statefrom a sensory receptor through a nerve network to an effector the site at which the response occurs.

They transmit sensory signals and motor commands. See it in 3D. The brain is the control center and the spinal cord is the major highway to and from the brain. The nervous system is a network of neurons whose main feature is to generate modulate and transmit information between all the different parts of the human body.

The nervous system or the neural system is a complex network of neurons specialized to carry messages. The central nervous system comprises the brain and the spinal cord. The bodily system that in vertebrates is made up of the brain and spinal cord nerves ganglia and parts of the receptor organs and that receives and interprets stimuli and transmits impulses to the effector organs see autonomic nervous system central nervous system peripheral nervous system. They conduct electrical signals to pass information through the body.

Through these physical structures thought emotion and sensation are experienced and body movements are coordinated. What is the nervous system. The central nervous system CNS consists of the brain and spinal cord. The central nervous system CNS consists of the brain and the spinal cord.

It also controls other body systems and processes such as digestion breathing and sexual development puberty. To limit the effects of damage caused by accidents the central and peripheral nervous systems are protected by a robust internal skeleton such as the skull and vertebral column. This body system is responsible for integrating and coordinating the activities of the entire body. We can say that A joint is a point at which two or more bones come into contactThey are built to e.

American Heritage Dictionary of the English Language Fifth Edition. For instance cnidarians such as jellyfish have relatively simple nerve nets spread throughout their body. The system of cells tissues and organs that regulates the bodys responses to internal and external stimuli.

Neurons are charged cells. It is the bodys communication system that controls much of what your body does. The nervous system controls everything you do including breathing walking thinking and feeling. The limbic system also known as the paleomammalian cortex is a set of brain structures located on both sides of the thalamus immediately beneath the medial temporal lobe of the cerebrum primarily in the forebrain.

Originating from your brain it controls your movements thoughts and automatic responses to the world around you. Definition The nervous system maintains internal order within the body by coordinating the activities of muscles and organs receives input from sense organs trigger reactions generating learning and understanding and providing protection from danger.

The nervous system is made up of the brain spinal cord and nerves. All living organisms are aware of the changes occurring in their external environment like change in light temperature sound movement and smell. What is the definition of autonomic and voluntary nervous system. All nervous tissue from the brain to the spinal cord to the furthest nerve branch includes cells called neurons.

It is further classified into the central nervous system and the peripheral nervous system. What are the characteristics of a fibrous jointName the three types and give an example of each. However the brain cannot do this alone as it needs to receive information from the bodys sense receptors which it achieves through communication with. The autonomic nervous system is a complex set of neurons that mediate internal homeostasis without conscious intervention or voluntary control.

The nervous system is a complex network of nerves and cells that carry messages to and from the brain and spinal cord to various parts of the body. The brain and spinal cord are two parts of the central nervous system. The network of nerve cells and fibres which transmits nerve impulses between parts of the body. It is composed of the brain spinal cord and nerves which act together to serve as the communicating and coordinating system of the body carrying information to the brain and.

See also autonomic nervous system central nervous system peripheral nervous. This system innervates most body parts and influences their activity as well as mediating changes to the overall metabolism. Your nervous system is made up of. The meaning of CENTRAL NERVOUS SYSTEM is the part of the nervous system which in vertebrates consists of the brain and spinal cord to which sensory impulses are transmitted and from which motor impulses pass out and which coordinates the activity of the entire nervous system.

The nervous system is the controlling system of the body and is composed of nerve cells and organs.
