MULTIPLE CHOICE

1. ANS: A
The extraocular muscles control eye movements. They include the medial and lateral rectus muscles, the
superior and inferior rectus muscles, and the superior and inferior oblique muscles.

PTS: 1
2. ANS: C
The masseter muscles are primarily used in chewing. Extraocular and facial muscles are used to squint and
sniff. Grasping is performed by the intrinsic muscles of the hands.

PTS: 1
3. ANS: C
Drooping of the eyelids is a condition known as ptosis. It is a common finding in several diseases, including,
for example, myasthenia gravis.

PTS: 1
4. ANS: D
The lingual muscle (also known as the tongue) is used to speak, chew, and swallow.

PTS: 1
5. ANS: D
Weakness of facial muscles often results in loss of facial definition, such as effacement of the nasolabial fold.
This is a common finding in Bell’s palsy, a peripheral nerve palsy that paralyzes one half of the face.

PTS: 1
6. ANS: B
The elbow flexes when the biceps muscle of the arm contracts. The triceps muscle extends the elbow. The
pectoralis major and minor muscles are muscles of the chest wall.

PTS: 1
7. ANS: B
The voluntary elevation of the toes off the floor (or “toward the nose”) is called dorsiflexion. Plantar flexion
of the toes is performed by curling or flexing the toes toward the floor.

PTS: 1
8. ANS: A
External rotation of the hip is any movement in which the hip joint turns away from the body’s midline.
Internal hip rotation involves movement of the joint toward the midline. Flexion of the hip is performed by
bringing the knee toward the chest. The hip extends when the leg is drawn backward (away from the body’s
anterior surface).

PTS: 1
9. ANS: B

, The soleus, one of the deep muscles of the calf, is used during jumping. The trapezius is a muscle that links
the upper back, neck and shoulders. The serratus muscles are found on the trunk. The pectoralis minor muscle
is a muscle of the chest.

PTS: 1
10. ANS: A
The flexor carpi radialis, as the name implies is a muscle on the radial side of the wrist (in Latin, the
“carpus”). The other listed muscles are found in the leg.

PTS: 1
