OTP-502 Practical 1 ACTUAL UPDATED QUESTIONS AND CORRECT ANSWERS
SC joint articulation of the medial end of clavicle with sternum. Acts as pivot for shoulder
motion (elevation, depression, rotation)
AC joint articulation of acromion and distal end of clavicle. Contributes to stability, force
transmission, and overhead motion.
Spine of Scapula Divides supra- and infraspinatus
, Medial border of scapula Attachment point for stabilizing muscles like rhomboids and serratus anterior
Inferior Angle of scapula -It serves as an attachment for the serratus anterior
-Is important for scapular upward rotation
-Helps with tracking during shoulder elevation
Greater Tubercle of Humerus Insertion point for three rotator cuff muscles: supraspinatus, infraspinatus, and
teres minor
Lesser tubercle of humerus Attachment for subscapularis; involved in internal rotation of the shoulder.
Bicipital/Intertubercular Groove Holds the tendon of long head of biceps (anterior part of shoulder)
Olecranon Process of Ulna -Insertion for Tricep muscles
-Crucial for elbow extension
-Stabilizer against joint displacement
Lateral epicondyle of humerus Attachment point for wrist extensor-supinator muscles and the lateral collateral
ligament (LCL)
