Human nervous system, the series of cells and nerve tracts that conduct stimuli from sensory receptors in the periphery to receptors in the brain and spinal cord and then conduct impulses back to other body parts.
Your nervous system is the command center for your entire body. It helps you think, learn, move and remember. This vast network of nerves connects to all of your organs, muscles and glands.
The nervous system consists of nervous tissue which, at a cellular level, is defined by the presence of a special type of cell, called the neuron. Neurons have special structures that allow them to send signals rapidly and precisely to other cells.
The nervous system (NS) is structurally broken down into two divisions; Central nervous system (CNS) - consists of the brain and spinal cord; Peripheral nervous system (PNS) - gathers all neural tissue outside the CNS; Functionally, the nervous system can be categorized into three main areas: sensation, integration and response.
The nervous system in a human is made of the brain, spinal cord, sensory organs and all the neurons that serve as communication channels between the various organs of the body. It is primarily made of a single type of cell called the neuron. Colloquially, they are also called nerve cells.
The nervous system has two major parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The central system is the primary command center for the body, and is...
The human nervous system controls all activities of the body in a quicker fashion. It can be divided into the central nervous system and peripheral nervous system. The central nervous system includes spinal cord and brain and the peripheral covers the nerves branching from spinal cord and brain.
Nervous system, organized group of cells specialized for the conduction of electrochemical stimuli from sensory receptors. The nervous system allows for the almost instantaneous transmission of electrical impulses from one region of the body to another.
