Glenoid cavity articulates :

Options

A. Clavicle with scapula
B. Humerus with scapula
C. Clavicle with acromion
D. Scapula with acromion

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks what the glenoid cavity articulates with. This requires knowledge of the anatomy of the shoulder joint.

2. **Identifying the Glenoid Cavity**: The glenoid cavity is a part of the scapula (shoulder blade). It is a shallow socket that plays a crucial role in the shoulder joint.

3. **Recognizing the Function of the Glenoid Cavity**: The primary function of the glenoid cavity is to articulate with the head of the humerus, which is the bone of the upper arm.

4. **Analyzing the Options**:
- Option A: Clavicle with scapula - This is incorrect as the clavicle connects to the scapula at the acromion, not the glenoid cavity.
- Option B: Humerus with scapula - This is correct because the head of the humerus fits into the glenoid cavity.
- Option C: Clavicle with acromion - This is also incorrect as it does not involve the glenoid cavity.
- Option D: Scapula with acromion - This is incorrect as the acromion is part of the scapula and does not articulate with the glenoid cavity.

5. **Conclusion**: Based on the analysis, the correct answer is that the glenoid cavity articulates with the head of the humerus.

### Final Answer:
The glenoid cavity articulates with the head of the humerus.
