PATHOLOGY

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.

Detailed explanation-2: -The dendrites receive messages from other cells or the environment. The cell body contains the nucleus and other important organelles. The axon is a long projection from the cell body that carries the signal in the neuron to the terminal.

Detailed explanation-3: -Dendrites are extensions, or processes, of the cytoplasm that carry impulses to the cell body. An extension or process called an axon carries impulses away from the cell body. Nervous tissue also includes cells that do not transmit impulses, but instead support the activities of the neurons.

Detailed explanation-4: -Transmission of a signal between neurons is generally carried by a chemical called a neurotransmitter. Transmission of a signal within a neuron (from dendrite to axon terminal) is carried by a brief reversal of the resting membrane potential called an action potential.

Detailed explanation-5: -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.
