Function: Neurons carry electrical signals called impulses. They receive information through dendrites, process it in the cell body (Soma), and send it out through the axon to other neurons, muscles, or glands. Function: It contains the nucleus and controls the neuron's activities, keeping it alive and processing information. EX: In response to a message from dendrites, the soma decides whether to pass the signal along the axon. 3. Dendrites Dendrites are branch-like extensions of a neuron Function: They receive messages from other neurons and pass them to the soma. EX: Dendrites receive signals when you hear your name and send them to your brain to process. 4. Axon An axon is a long fiber that extends from a neuron. Function: It carries electrical signals away from the soma to other neurons, muscles, or glands. EX: An axon sends the signal that makes your hand move when you catch a ball. 5. Action Potential An action potential is an electrical signal that a neuron sends. Function: It travels down the axon to tr...
