Nov 3, 2023 · 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.
Jun 3, 2024 · nervous system, organized group of cells specialized for the conduction of electrochemical stimuli from sensory receptors through a network to the site at which a response occurs. Follow the electrical and chemical changes undergone to transmit an impulse through the human nervous system.
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 or the neural system is a complex network of neurons specialized to carry messages. The complexity of the nervous system increases as we move towards higher animals. For instance, cnidarians such as jellyfish have relatively simple nerve nets spread throughout their body.
Nov 16, 2023 · Your nervous system is your body’s command center. It’s made up of your brain, spinal cord and nerves. Your nervous system works by sending messages, or electrical signals, between your brain and all the other parts of your body.
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.
Feb 5, 2018 · 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...
Feb 10, 2021 · The nervous system is an enormously complex system for coordinating an animal’s behavior and helping it navigate and react to the outside environment. In the least complex organisms, the nervous system can consist of only a few neurons and no central brain.
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). But there is a third function that needs ...
May 12, 2023 · 2 min read. Fibers called nerves carry important messages back and forth between your body and your brain. That network -- your nervous system -- has two parts: Your brain and spinal cord make up...
