Axon
A threadlike extension of a neuron that carries nerve impulses away from the cell body.
An axon is a long, slender projection of a neuron that typically conducts electrical impulses away from the neuron’s cell body. It is the main transmitting unit of nerve cells, and it carries information to other neurons, muscles, and glands. The axon is classified into two types: myelinated and unmyelinated. Myelinated axons are surrounded by a fatty layer called myelin which acts as an insulator and helps in the faster transmission of electrical signals. In contrast, unmyelinated axons do not have a myelin sheath, resulting in slower transmission of electrical signals. The length of axons varies, from a few micrometers to up to a meter in some cases. The end of an axon, called the axon terminal, forms synapses with other neurons or with muscles or glands, allowing for the transmission of signals between cells.
