At what site on the scapula does the humerus articulate?Multiple choice question.coracoid processspineacromionglenoid cavity

Break Down the Problem

1. We need to identify the specific site on the scapula where the humerus articulates.
2. The options provided are:
   • Coracoid process
   • Spine
   • Acromion
   • Glenoid cavity

Relevant Concepts

• The articulation between the humerus and scapula involves a specific cavity where the head of the humerus fits.

Analysis and Detail

1. Coracoid Process: This is a small hook-like structure on the scapula, primarily for muscle and ligament attachment rather than articulation.
2. Spine: The spine of the scapula is a prominent ridge but does not serve as a point of articulation with the humerus.
3. Acromion: This is the outermost part of the spine of the scapula, also not the site for humeral articulation.
4. Glenoid Cavity: This is a shallow cavity on the scapula that is specifically designed to articulate with the head of the humerus, forming the shoulder joint.

Verify and Summarize

The correct site where the humerus articulates with the scapula is the glenoid cavity. The other options are anatomical structures that do not directly articulate with the humerus.

Final Answer

The humerus articulates with the scapula at the glenoid cavity.
