Within a nervous system, a neuron, neurone, or nerve cell is an electrically excitable cell that fires electric signals called action potentials across a neural network.
Learn about the basic units of the nervous system, neurons, and how they receive, process, and transmit information. Explore the anatomy, classes, and roles of neurons, and how they are organized into circuits.
26 de abr. de 2021 · Learn what a nerve cell (neuron) is, how it works, and what are the three types of nerve cells in the human body. Find out how nerve cells form the nervous system and process information from the environment.
Nerve Cells. Despite the specific molecular, morphological, and functional features of any particular nerve cell type, the basic structure of neurons resembles that of other cells. Thus, each nerve cell has a cell body containing a nucleus, endoplasmic reticulum, ribosomes, Golgi apparatus, mitochondria, and other organelles that are essential ...
Learn about the structure and function of neurons, the specialized cells that transmit and receive electrical signals in the body. Watch a video and read a transcript, and explore questions and answers from other learners.
Anatomy of a nerve cell. Structural features of a motor neuron include the cell body, nerve fibres, and dendrites. With few exceptions, most neurons consist of three distinct regions, as shown in the diagram: (1) the cell body, or soma; (2) the nerve fibre, or axon; and (3) the receiving processes, or dendrites.
Neurons are the structural and functional units of the nervous system. They consist of a cell body, dendrites, and axon. Neurons transmit nerve impulses to other cells. Types of neurons include sensory neurons, motor neurons, and interneurons.
