CCAT Anatomy & Physiology 5

Question 1

Which anatomical feature of the feline thoracic limb allows cats to supinate their forepaws more effectively than dogs?

Accepted Answer

Separate radius and ulna with greater rotational mobility

Answer

Cats have a separate radius and ulna that rotate more freely relative to each other, enabling the supination needed for grasping prey.

Question 2

The 'stay apparatus' in the horse has a feline equivalent concept — in dogs, which passive mechanism assists in maintaining the extended elbow during weight bearing?

Accepted Answer

Locking of the olecranon in the trochlear notch

Answer

The olecranon process locking into the humeral trochlear notch provides passive bony stability of the extended elbow during stance in dogs.

Question 3

In rehabilitation of companion animals, understanding that the gastrocnemius muscle crosses which two joints is critical for treatment planning?

Accepted Answer

Stifle and hock (tarsocrural)

Answer

The gastrocnemius is a biarticular muscle crossing both the stifle (origin on femoral condyles) and the hock (insertion on calcaneus), so tightness affects both joints.

Question 4

Which lymph nodes are most clinically relevant when assessing lymphatic drainage from the canine pelvic limb during a physical examination?

Accepted Answer

Popliteal and inguinal nodes

Answer

The popliteal node (caudal to the stifle) and inguinal nodes drain the hindlimb and are routinely palpated in hindlimb assessment.

Question 5

In canine anatomy, the 'common calcanean tendon' (Achilles tendon equivalent) is formed by contributions from which muscles?

Accepted Answer

Gastrocnemius, superficial digital flexor, biceps femoris, gracilis, and semitendinosus

Answer

The canine common calcanean tendon receives contributions from the gastrocnemius, superficial digital flexor, biceps femoris, gracilis, and semitendinosus muscles.
