What is a "neuron"?
A neuron, also known as a nerve cell, is a specialized cell that is the fundamental unit of the nervous system. Neurons are responsible for transmitting information throughout the body, allowing us to think, feel, and move. They have a unique structure that includes dendrites, a cell body, and an axon. Dendrites receive signals from other neurons, while the cell body processes this information. The axon, which can be very long, carries electrical impulses away from the cell body and towards other neurons, muscles, or glands. Communication between neurons occurs through synapses, small gaps between the axon of one neuron and the dendrites of another.
Exemple
The dendroid neurons in the brain resemble trees, with axons and dendrites branching out from the cell body.
The synaptic cleft is the small gap between adjacent neurons across which neurotransmitters are released.
Synapses play a crucial role in information processing in the nervous system, allowing communication between neurons.
Multipolar neurons are the most common type of neuron found in the brain and spinal cord.
Synaptic transmission is the process by which nerve impulses are passed from one neuron to another.
