MICROANATOMY

Detailed explanation-1: -Neurons send and receive electrical signals to communicate with each other in the nervous system and with other types of cells in the body, particularly muscles. At one end, neurons have branch-like projections called dendrites that allow them to receive signals.

Detailed explanation-2: -The spinal cord runs from the brain down through the back. It contains threadlike nerves that branch out to every organ and body part. This network of nerves relays messages back and forth from the brain to different parts of the body.

Detailed explanation-3: -Motor or efferent neurons transmit impulses from the central nervous system towards the effectors (muscle or glands), while sensory neurons transmit impulses from the sense organs towards the central nervous system (brain and spinal cord).
