Humerus Bone Markings Quiz #3

Study Notes

Humerus Bone Markings

Head of Humerus: Rounded proximal end that articulates with the glenoid cavity of the scapula, forming the shoulder joint.
Greater Tubercle: Large, lateral projection located below the head; serves as an attachment point for the rotator cuff muscles, specifically the supraspinatus, infraspinatus, and teres minor.
Lesser Tubercle: Smaller, anterior projection situated below the head; primarily serves as an attachment point for the subscapularis muscle.
Deltoid Tuberosity: Rough, raised area on the lateral surface of the humerus; provides an attachment site for the deltoid muscle which is crucial for shoulder abduction.
Capitulum: Rounded knob-like structure on the distal end of the humerus; articulates with the head of the radius, allowing for elbow joint movement.
Trochlea: spool-shaped structure located medial to the capitulum; articulates with the ulna, forming a hinge joint crucial for flexion and extension of the elbow.
Olecranon Fossa: Deep triangular depression on the posterior aspect of the distal humerus; accommodates the olecranon process of the ulna during elbow extension.
Coronoid Fossa: Smaller depression located anteriorly above the trochlea; receives the coronoid process of the ulna during elbow flexion.
