Learning Objective
I can describe the main functions of the nervous system.
- 1
The nervous system can be divided into two general regions: the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS), which includes all other components.
- 2
The hindbrain includes the medulla, pons, and cerebellum, which regulate functions like breathing, heart rate, balance, and movement coordination.
- 3
Neurons communicate with each other through a process called action potential, which involves a rapid change in electrical charge along the axon and the release of neurotransmitters at the synapse.
