Quiz Answer Key and Fun Facts

1. What is the connective tissue around an individual axon called?

Answer: Endoneurium

Perineurium is the covering around a group of axons. Epineurium is the covering around the entire nerve.

2. What is the superficial connective tissue around the ENTIRE nerve called?

Answer: Epineurium

Carpal tunnel syndrome is a condition caused by a nerve within the wrist that is pinched. The most serious case of carpal tunnel syndrome is when the epineurium and endoneurium have been impaired. It is considered serious because the endoneurium protects the axon and the epineurium protects the nerve.

3. If Jane Doe is in an automobile accident and has complete spinal cord damage ABOVE the phrenic nerve, would that cause her to go into respiratory arrest?

Answer: Yes

The phrenic nerve supplies the diaphragm and the diaphragm is a very important muscle for breathing.

4. Ulnar nerve injury could cause a(an) _____________ .

Answer: All of these

The ulnar nerve is located within the forearm and when it is injured, it affects the elbow, arm, and the ring and small fingers. It causes a limp wrist and makes it difficult to move the ring and small fingers.

5. What is the largest lumbar nerve that also supplies the anterior part of the thigh?

Answer: Femoral

The obturator nerve provides motor nerve stimulus to the thigh. The axillary nerve provides nerve stimulus to the arm and the sciatic nerve provides nerve stimulus to the legs.

6. The body has membranous coverings called meninges that surround what?

Answer: Brain and Spinal Cord

There are three meninges: dura mater, arachnoid, and pia mater. Dura mater means "tough mother" and is the closest to the bone and pia mater means "tender or kind mother" and is closest to the brain or spinal cord.

7. The sequence of layers of meninges in the human body is:

Answer: Bone, Dura Mater, Arachnoid, Pia Mater, Brain or Spinal Cord

The longer version of the sequence is bone (skull or vertebrae), epidural space, dura mater, subdural space, arachnoid, subarachnoid space, pia mater, brain or spinal cord.

8. When a doctor strokes the sole of the foot, causing the big toe to fan with or without the other toes, the procedure is called Babinski's Sign.

Answer: True

Babinski's sign is an indication of spinal tract damage. The normal response is curling of all of the toes.

9. Which one of these is NOT an ascending spinal tract?

Answer: Extrapyramidal

Fasciculus Gracilis tract deals with fine touch, spinothalamic tract deals with pain, temperature, touch and pressure, and spinocerebellar tract deals with unconscious body movement. Extrapyramidal tract is a descending tract that deals with the motor response to unconscious movement of the body.

10. Which of these is a major motor tract of the body that is also a descending tract?

Answer: Pyramidal

The spinothalamic tract and spinocerebellar tract are both ascending tracts. The extrapyramidal is a descending tract but is not the major tract of the body. The pyramidal tract is also known as the corticospinal tract.
