Which type of cartilage covers the articular surfaces of synovial joints?
Answer: Hyaline cartilage
Hyaline cartilage covers articular surfaces, providing a smooth, low-friction surface for joint movement.
The anterior cruciate ligament (ACL) primarily prevents which motion at the knee?
Answer: Anterior tibial translation
The ACL primarily resists anterior translation of the tibia on the femur and also limits internal rotation.
Which muscle is responsible for depression and protraction of the scapula?
Answer: Serratus anterior
Serratus anterior protracts and upwardly rotates the scapula while also holding it flat against the thorax.
In osteoarthritis, the primary pathological change occurs in which tissue?
Answer: Articular cartilage
Osteoarthritis is characterized by progressive degradation of articular cartilage, leading to joint space narrowing and pain.
The rotator cuff muscle that initiates shoulder abduction by depressing the humeral head is the:
Answer: Supraspinatus
Supraspinatus initiates the first 15–30 degrees of abduction and works to depress the humeral head in the glenoid.
Which nerve passes through the carpal tunnel and is commonly compressed in carpal tunnel syndrome?
Answer: Median nerve
The median nerve travels through the carpal tunnel and innervates the thenar muscles and lateral three-and-a-half digits.
A Grade II ligament sprain is defined by:
Answer: Partial tearing with some functional loss and laxity
A Grade II sprain involves partial tearing of ligament fibers, resulting in some functional loss, pain, swelling, and measurable but not gross laxity.
