Using the Figure, match the following:
1) Innervates the superior oblique muscle.
2) Longest cranial nerve.
3) Damage to this nerve would cause dizziness, nausea, and loss of balance.
4) Involved in movement of the digestive tract.
5) Damage to this nerve would cause difficulty in speech and swallowing, but no effect on visceral organs.
6) Damage to this nerve would keep the eye from rotating inferolaterally.
Using the Figure, identify the following components of the reflex arc:
7) Integration center.
8) Sensory neuron.
9) Effector.
10) Motor neuron.
11) Receptor.
Match the following:
A) Abducens
B) Vestibulocochlear
C) Olfactory
D) Vagus
E) Accessory
12) Formed by the union of a cranial and a spinal root.
13) Receptors located in epithelium of the nasal cavity.
14) Serves the senses of hearing and equilibrium.
15) Helps to regulate blood pressure and digestion.
16) Turns the eyeball laterally.
Match the following reflexes to their function:
A) Tendon
B) Stretch
C) Crossed-extensor
D) Flexor
E) Plantar
17) Tests both upper and lower motor pathways. The sole of the foot is stimulated with a dull instrument.
18) Consists of an ipsilateral withdrawal reflex and a contralateral extensor reflex; important in maintaining balance.
19) Produces a rapid withdrawal of the body part from a painful stimulus; ipsilateral.
20) Prevents muscle overstretching and maintains muscle tone.
21) Produces muscle relaxation and lengthening in response to tension; the contracting muscle relaxes as its antagonist is activated.
Match the following:
A) Brachial plexus
B) Cervical plexus
C) Lumbar plexus
D) Sacral plexus
22) The obturator and femoral nerves branch from this plexus.
23) Striking the "funny bone" (ulnar nerve) may cause injury to a nerve of this plexus.
24) Trauma to a nerve of this plexus may cause wrist drop.
25) A fall or improper administration of an injection to the buttocks may injure a nerve of this
