Stenoid cavity articulates `:-`

Options

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

Answer

**Step-by-Step Solution:**

1. **Understand the Question**: The question asks about the articulation of the glenoid cavity. The glenoid cavity is a part of the scapula (shoulder blade) that articulates with the humerus (the upper arm bone).

2. **Analyze the Options**: We need to evaluate the given options to determine which one correctly describes what the glenoid cavity articulates with.

3. **Evaluate Option 1**: The first option states that the glenoid cavity articulates with the scapula at the acromion. This option is incorrect because the acromion is a part of the scapula itself and does not articulate with the glenoid cavity.

4. **Evaluate Option 2**: The second option suggests that the glenoid cavity articulates with the clavicle. This is also incorrect because the clavicle does not directly articulate with the glenoid cavity; rather, it articulates with the acromion of the scapula.

5. **Evaluate Option 3**: The third option states that the glenoid cavity articulates with the humerus. This is the correct answer because the glenoid cavity is specifically designed to articulate with the head of the humerus, forming the shoulder joint.

6. **Evaluate Option 4**: The last option mentions the clavicle with the acromion. This option is incorrect as it does not pertain to the glenoid cavity.

7. **Conclusion**: After evaluating all options, the correct answer is that the glenoid cavity articulates with the humerus.

**Final Answer**: The glenoid cavity articulates with the humerus.
