Cerebellum Located at the back of the brain under the cerebrum. It helps you stay balanced and coordinates your movements so they’re smooth and controlled.

Brainstem Connects the brain to the spinal cord. It controls automatic functions that keep you alive, like breathing, heart rate, and blood pressure. It also helps control sleep and reflexes.

The largest part of the brain. It’s responsible for thinking, memory, learning, emotions, speech, and voluntary movements. It also processes information from your senses — sight, touch, hearing, taste, and smell.

• dendrite: receives messages from other neurons and sends them to the cell body.
• cell body (soma) Contains the nucleus; controls the cell and processes information.
• Axon: Carries signals away from the cell body to other neurons or muscles.
• Myelin Sheath fatty covering around the axon that makes signals travel faster.
• Nodes of Ranvier: Gaps in the myelin where the signal jumps to speed up transmission.
• Axon Terminals: End of the neuron; release neurotransmitters to send the message on. Synapse
• Tiny gap where messages pass from one neuron to another.

A neuron is a special nerve cell that sends and receives messages in the brain and nervous system. Neurons communicate through tiny electrical impulses and chemical messengers called neurotransmitters. Messages travel across small gaps between neurons called synapses.
