Unit III
Module 10

2. The Nervous System Nervous System: Nerves:
The body’s speedy, electrochemical communication network
Consists of central and peripheral nervous system
Nerves:
Bundled axons that form neural “cables” connecting the central nervous system with muscles, glands, and sense organs

The brain and spinal cord
Interneurons communicate in the spinal cord (reflexes)
Peripheral Nervous System (PNS):
