Which type of cartilage covers the articular surfaces of bones in synovial joints of companion animals?
Answer: Hyaline cartilage
Hyaline cartilage covers articular surfaces, providing a smooth, low-friction interface for joint movement.
In dogs, the caudal cruciate ligament primarily prevents which movement of the tibia relative to the femur?
Answer: Caudal tibial displacement
The caudal cruciate ligament resists caudal displacement of the tibia relative to the femur.
Which muscle group is primarily responsible for extension of the canine stifle joint?
Answer: Quadriceps femoris group
The quadriceps femoris group, including the rectus femoris and three vasti, extends the stifle joint.
What is the primary function of the supraspinatus muscle in the canine forelimb?
Answer: Extension and stabilization of the shoulder
The supraspinatus extends and stabilizes the shoulder joint, preventing excessive flexion during weight bearing.
In companion animal anatomy, the term 'volar' refers to which surface of the distal limb?
Answer: Caudal/palmar or plantar surface
Volar refers to the caudal surface of the distal limb, equivalent to the palmar (forelimb) or plantar (hindlimb) surface.
Which nerve innervates the biceps brachii muscle in dogs and is commonly tested in neurological examinations?
Answer: Musculocutaneous nerve
The musculocutaneous nerve innervates the biceps brachii, and the biceps reflex tests spinal segments C6-C8.
The sacroiliac joint in dogs is classified as which type of joint?
Answer: Syndesmosis (fibrous joint)
The sacroiliac joint is a syndesmosis, a fibrous joint held together by interosseous ligaments with minimal mobility.
