Nervous System: What It Is, Parts, Function & Disorders - Cleveland Clinic
2023年11月16日 · The nervous system has two main parts: Central nervous system (CNS): Your brain and spinal cord make up your CNS. Your brain reads signals from your nerves to regulate how you think, move and feel. Peripheral nervous system (PNS): Your PNS is made up of a network of nerves. The nerves branch out from your spinal cord.
Nervous system - Wikipedia
In vertebrates, it consists of two main parts, the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS consists of the brain and spinal cord. The PNS consists mainly of nerves, which are enclosed bundles of the long fibers, or axons, that connect the CNS to every other part of the body.
Overview of the nervous system: Structure and function | Kenhub
2023年11月3日 · 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. This property enables many important functions of the nervous system, such as regulation of vital body functions (heartbeat, breathing, digestion), sensation and body movements.
Neurophysiology: Nervous system function and structure - Kenhub
2024年9月18日 · Nervous system. From a structural point of view, the nervous system is divided into two major components: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS includes the brain and spinal cord, serving as the main control center.
Nervous system | Definition, Function, Structure, & Facts | Britannica
2024年9月25日 · A nervous system can be defined as an organized group of cells, called neurons, specialized for the conduction of an impulse—an excited state—from a sensory receptor through a nerve network to an effector, the site at which the response occurs.
Nerves: Types, Function & Anatomy - Cleveland Clinic
Nerves, together with your brain and spinal cord, are the foundation of your nervous system. Most of the time when doctors use the term “nerve,” they’re referring to the part of your nervous system outside of your brain and spinal cord.
12.1 Basic Structure and Function of the Nervous System
The nervous system is involved in receiving information about the environment around us (sensation) and generating responses to that information (motor responses). The nervous system can be divided into regions that are responsible for sensation (sensory functions) and for the response (motor functions).
Nerve: anatomy, definition, types, functions - Kenhub
2023年10月30日 · Nerves are the functional and structural units of the peripheral nervous system (PNS). They are composed of groups of individual specialized cells called neurons (or nerve cells), which transmit motor and sensory information back and forth between the PNS and central nervous system (CNS) .
human nervous system - Encyclopedia Britannica
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.
