Key Concepts

Axon Terminal (Synaptic Terminal)

The axon terminal is the specialized end of the axon where the neuron communicates with its target cells. It releases neurotransmitters into the synapse, a gap between the axon terminal and the receiving cell, allowing the transmission of the signal to the next cell in the neural network.

Axon

The axon is a long, slender projection that conducts electrical impulses away from the cell body. It serves as the main conduit for transmitting the integrated signal towards other neurons, muscles, or glands, often supported by a myelin sheath to speed up the signal propagation.

Neuron

A neuron is a specialized cell in the nervous system that transmits and processes information through electrical and chemical signals. It consists of distinct structural parts that work together to receive, integrate, and send impulses across long distances.

Dendrites

Dendrites are branched extensions at the beginning of a neuron that receive incoming signals from other nerve cells. They act as the primary input sites for information, gathering chemical signals and transmitting them toward the cell body for processing.

Soma (Cell Body)

The soma, or cell body, is the central part of the neuron that contains the nucleus and other organelles. It integrates the incoming signals from the dendrites, determining whether to generate an outgoing electrical impulse, and maintains the cell’s overall health and metabolic functions.
