support for weight-bearing activities.
2. What is the primary function of the acetabulofemoral joint in cats?
,A) Flexion of the hindlimb
B) Extension of the forelimb
C) Weight bearing and locomotion of the hindlimb — CORRECT
ANSWER
D) Rotation of the head
Rationale: The acetabulofemoral (hip) joint is a ball-and-socket joint
that allows the hindlimb to bear weight and move during
locomotion.
3. Which muscle is the most powerful extensor of the canine carpus?
A) Flexor carpi radialis
B) Extensor carpi radialis — CORRECT ANSWER
C) Brachialis
,D) Supraspinatus
Rationale: The extensor carpi radialis provides strong extension of
the carpal joint in dogs, enabling them to bear weight on their
forelimbs.
4. In the equine heart, the interventricular septum is composed
primarily of which tissue?
A) Skeletal muscle
B) Fibrous connective tissue
C) Cardiac muscle — CORRECT ANSWER
D) Adipose tissue
Rationale: The septum separating the left and right ventricles is made
of cardiac (myocardial) muscle, which is responsible for the
coordinated contraction of the heart.
5. Which chamber of the canine heart receives oxygenated blood
from the lungs?
, A) Right atrium
B) Left atrium — CORRECT ANSWER
C) Right ventricle
D) Left ventricle
Rationale: Pulmonary veins deliver oxygen-rich blood from the lungs
to the left atrium, which then passes it to the left ventricle for
systemic circulation.
6. What structure in the bovine lung is responsible for gas exchange?
A) Bronchioles
B) Alveoli — CORRECT ANSWER
C) Trachea
D) Pleura
