What type of cells are responsible for communication within the body?

Neurons are the specialized cells responsible for communication within the body. They transmit information throughout the nervous system by sending electrical impulses and releasing neurotransmitters. This communication is crucial for various functions, including sensory perception, motor control, and cognitive processes.

While glial cells play supportive roles, such as protecting and nourishing neurons, they do not directly facilitate communication. Muscle cells are involved in movement and contraction, whereas epithelial cells form protective barriers and are involved in absorption and secretion but do not serve the purpose of communication within the body.
