CCAT Anatomy & Physiology 2

Question 1

Which type of cartilage covers the articular surfaces of bones in synovial joints of companion animals?

Accepted Answer

Hyaline cartilage

Answer

Hyaline cartilage covers articular surfaces, providing a smooth, low-friction interface for joint movement.

Question 2

In dogs, the caudal cruciate ligament primarily prevents which movement of the tibia relative to the femur?

Accepted Answer

Caudal tibial displacement

Answer

The caudal cruciate ligament resists caudal displacement of the tibia relative to the femur.

Question 3

Which muscle group is primarily responsible for extension of the canine stifle joint?

Accepted Answer

Quadriceps femoris group

Answer

The quadriceps femoris group, including the rectus femoris and three vasti, extends the stifle joint.

Question 4

What is the primary function of the supraspinatus muscle in the canine forelimb?

Accepted Answer

Extension and stabilization of the shoulder

Answer

The supraspinatus extends and stabilizes the shoulder joint, preventing excessive flexion during weight bearing.

Question 5

In companion animal anatomy, the term 'volar' refers to which surface of the distal limb?

Accepted Answer

Caudal/palmar or plantar surface

Answer

Volar refers to the caudal surface of the distal limb, equivalent to the palmar (forelimb) or plantar (hindlimb) surface.
