Study Notes
Central Nervous System (CNS)
- Consists of the brain and spinal cord
Peripheral Nervous System (PNS)
- Consists of all nervous tissues outside the CNS, including nerves, ganglia, and sensory receptors
- Consists of nervous tissue outside the CNS
- Acts as a messenger, delivering CNS decisions to the rest of the body
Nerve Pairs
- Cranial nerves have 21 pairs
- Spinal nerves have 13 pairs
Control Systems
- Two major control systems: sensory and motor
Nerve Function
- Carries information to the CNS (sensory function)
- Carries information to the body from the CNS (motor function)
- Processes information within the CNS (integration function)
Neuron Structure
- Typical neuron structure: many dendrites, 1 axon
- Another type of neuron structure: 1 dendrite, 1 axon
