Nervous System Basics
- The nervous system divides into the central nervous system (CNS) and the peripheral nervous system (PNS).
- The CNS processes and integrates information; the PNS carries sensory input to and motor output from the CNS.
Neuron Structure and Function
- Neurons are the functional units of the nervous system with dendrites, a cell body, and a long axon.
- Axons carry electrical impulses to axon terminals for chemical communication via neurotransmitters.
Resting Membrane Potential
- The sodium-potassium pump maintains the neuron's resting membrane potential by pumping 3 sodium ions out and 2 potassium ions in.
- This creates an electrical and chemical gradient with a resting potential near -70 millivolts inside the cell.
