Learn about the nervous system, the command center for your body. It consists of your brain, spinal cord and nerves that send messages to regulate your thoughts, movements, senses and more.
3 lis 2023 · Neurons, or nerve cell, are the main structural and functional units of the nervous system. Every neuron consists of a body (soma) and a number of processes (neurites). The nerve cell body contains the cellular organelles and is where neural impulses (action potentials) are generated.
18 wrz 2024 · At its core, neurophysiology examines how neurons, the fundamental units of the nervous system, communicate through electrochemical signals, how they integrate vast amounts of information, and how they generate precise, coordinated responses to both internal and external stimuli.
The central nervous system functions to send signals from one cell to others, or from one part of the body to others and to receive feedback. Malfunction of the nervous system can occur as a result of genetic defects, physical damage due to trauma or toxicity, infection, or simply senescence.
25 wrz 2024 · Learn about the nervous system, a group of cells specialized for the conduction of electrochemical impulses in response to stimuli. Explore the types, features, and functions of nervous systems in different organisms, from simple to complex.
First, the basic functions of the nervous system are sensation, integration, and response. Secondly, control of the body can be somatic or autonomic—divisions that are largely defined by the structures that are involved in the response.
30 paź 2023 · 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).
