Detailed explanation-1: -Neurons, also known as nerve cells, send and receive signals from your brain. While neurons have a lot in common with other types of cells, they’re structurally and functionally unique. Specialized projections called axons allow neurons to transmit electrical and chemical signals to other cells.
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: -A nerve cell (neuron) consists of a large cell body and nerve fibers-one elongated extension (axon) for sending impulses and usually many branches (dendrites) for receiving impulses. The impulses from the axon cross a synapse (the junction between two nerve cells) to the dendrite of another cell.
