Neuron
A nerve cell which acts as the central building blocks of the nervous system. Pass signals between each other
A neuron, also known as a nerve cell, is the basic unit of the nervous system. It is responsible for transmitting information within the brain, spinal cord, and throughout the body.
The structure of a neuron includes a cell body, dendrites, axons, and terminal buttons. The cell body, also known as the soma, contains the nucleus and most of the cell’s organelles. Dendrites are short, branch-like structures that receive signals from other neurons and transmit them towards the cell body. Axons are long, thin fibers that transmit signals away from the cell body and towards other neurons or muscles. Terminal buttons, or axon terminals, are bulb-shaped structures that release neurotransmitters into the synapse, which is the gap between two neurons.
There are three main types of neurons: sensory neurons, motor neurons, and interneurons. Sensory neurons transmit information from sensory organs (such as the eyes or ears) to the central nervous system, while motor neurons transmit information from the central nervous system to the muscles. Interneurons integrate information from sensory and motor neurons and transmit it to other neurons.
Overall, neurons play a crucial role in allowing us to move, think, and feel. They are essential to the functioning of the nervous system and the body as a whole.
