Question 1

The rotator cuff consists of which four muscles?

Accepted Answer

Supraspinatus, infraspinatus, teres minor, and subscapularis

Answer

The SITS muscles (Supraspinatus, Infraspinatus, Teres minor, Subscapularis) form the rotator cuff and stabilize the glenohumeral joint.

Question 2

Which bone landmark serves as the primary insertion site for the quadriceps femoris muscle group?

Accepted Answer

Tibial tuberosity

Answer

The quadriceps tendons merge into the patellar tendon, which inserts onto the tibial tuberosity, enabling knee extension.

Question 3

Which joint classification describes the hip joint?

Accepted Answer

Ball and socket (spheroidal)

Answer

The hip is a ball-and-socket (spheroidal) joint between the femoral head and acetabulum, allowing movement in all three planes.

Question 4

The primary action of the gluteus medius muscle is:

Accepted Answer

Hip abduction and internal rotation

Answer

The gluteus medius is the primary hip abductor and also assists with internal rotation of the hip, critical for pelvic stability during gait.

Question 5

The anterior cruciate ligament (ACL) of the knee primarily resists:

Accepted Answer

Anterior tibial translation relative to the femur and rotational forces

Answer

The ACL prevents the tibia from sliding anteriorly on the femur and controls rotational stability, making it vulnerable in pivoting and cutting movements.
