5. Unit 3: Integration Station: The Nervous System
The Spinal Cord
Part of the Central Nervous System (CNS) that conducts nerve impulses to and from the brain.
Unit 3: Integration Station: The Nervous System
Slide 7.11

6. The Spinal Cord FUNCTIONS
1. Conduction of nerve impulses.
Two way communication system between the brain and the body – PATHWAYS or TRACTS.
ASCENDING TRACTS – Carry sensory info TO the brain
DESCENDING TRACTS – Send MOTOR impulses from the brain to MUSCLES & GLANDS.

7. Unit 3: Integration Station: The Nervous System
The Spinal Cord
Structure
The spinal cord is a slender nerve column that passes downward from the brain into the vertebral canal.
Consists of 31 segments, each of which gives rise to a pair of spinal nerves.
