ANATOMY

Detailed explanation-1: -An axon is a long single fiber that transmits messages from the cell body to the dendrites of other neurons or to other body tissues, such as muscles. A protective covering called the myelin sheath, covers most neurons. Myelin insulates the axon and helps nerve signals travel faster and farther.

Detailed explanation-2: -The parts of neurons that send messages are the axons, and the parts of neurons that receive messages are the dendrites. 3. The space between the dendrites of one neuron and the axon of another neuron is called the synapse.

Detailed explanation-3: -The synapse is the terminal region of the axon and it is here where one neuron forms a connection with another and conveys information through the process of synaptic transmission.

Detailed explanation-4: -The axon is a long slender fibre that carries nerve impulses, in the form of an electrical signal known as action potential, away from the cell body towards the axon terminals, where the neuron ends.

Detailed explanation-5: -Relay interneurons have long axons and connect circuits of neurons in one region of the brain with those in other regions.
