• AKA connection between brain and peripheral nervous system

• Can independently control some basic reflexes

How do you think the spinal cord is protected?

Guess 1 Guess 2

How is the spinal cord protected?

1. 33 bones called vertebrae, stacked on top of each other and separated by discs2. 3 layers of tissue called meninges

How is the spinal cord protected?

3. Surrounded by Cerebrospinal Spinal Fluid (CSF), which provides support and nutrients

What can go wrong with the spinal cord?

• Tetraplegia or quadriplegia is paralysis of the arms and legs– This involves both sensory

and motor deficits– Caused by damage to

spinal cord at a high level (C1 – C7)

• Paraplegia is paralysis of the legs– Damage to any vertebrae

below c7

Go Back to the Spinal Cord Diagram:What do the different sections of the

spinal cord do?

• Cervical-• Thoracic-• Lumbar-• Sacral-

• Cervical- sustains vitals (breathing, heart rate) and upper body movement

• Thoracic- movement of the trunk

• Lumbar- movement of legs

• Sacral- genital functioning, bowel and bladder activity

Check for Understanding: What’s wrong?

Directions: Label the section of the spinal cord.

1.Cervical

2.Thoracic

3.Sacral4.Lumbar

Check for Understanding: What’s wrong?

A young man has suffered a spinal cord injury and is having difficulty breathing. He cannot feel or move his legs, meaning he may be quadriplegic. Where is he most likely injured?

A.C4B.T11C.L2D.S1

Because the lumbar section of the spinal cord has to do with legs

Check for Understanding: What’s wrong?

(Level 4) What does it mean to be quadriplegic?

Quadriplegic means that you are paralyzed (can’t feel or move) from the waist down. Both legs don’t work.

Check for Understanding: What’s wrong?

(Level 4) How is the spinal cord protected?

The spinal cord is protected only by the vertebrae, or the muscles.
