Detailed explanation-1: -Synapse – The junction between the axon of one neuron and the dendrite of another, through which the two neurons communicate.
Detailed explanation-2: -Neurotransmitters pass through the synapse, the gap between two nerve cells, and attach to receptors on the receiving cell. This process repeats from neuron to neuron, as the impulse travels to its destination-a web of communication that allows you to move, think, feel and communicate.
Detailed explanation-3: -Axons pass the nerve impulses on to other cells. A single neuron may have thousands of dendrites, so it can communicate with thousands of other cells but only one axon. The axon is covered with a myelin sheath, a fatty layer that insulates the axon and allows the electrical signal to travel much more quickly.
Detailed explanation-4: -Axon. The axon is the elongated fiber that extends from the cell body to the terminal endings and transmits the neural signal.
Detailed explanation-5: -A neuron has three main parts: dendrites, an axon, and a cell body or soma (see image below), which can be represented as the branches, roots and trunk of a tree, respectively. A dendrite (tree branch) is where a neuron receives input from other cells.
