The major part of a neuron where the nucleus is located and metabolic activities occur.

Dendrites

Branching extensions from a neuron's cell body that receive signals from other neurons.

Schwann Cell

A type of glial cell located in the peripheral nervous system that wraps around axons, providing them with insulation and speeding up the transmission of nerve impulses.

Neuronal Processes

Neuronal processes refer to the various protrusions from a neuron's cell body, including axons and dendrites, which are essential for neural communication and signal transmission.
