Besides lungs, the term alveolus is associated with

Options

A. Bony cranium
B. Bony thoracic basket
C. Bony auditory capsule
D. Bony socket for tooth

Answer

**Step-by-Step Solution:**

1. **Understanding the Term "Alveolus":**
- The term "alveolus" primarily refers to the small air sacs in the lungs where gas exchange occurs. However, it can also refer to other structures in the body.

2. **Identifying the Role of Alveoli in the Lungs:**
- In the lungs, alveoli are crucial for respiration. They are thin-walled, irregularly shaped, and highly vascularized structures that facilitate the exchange of oxygen and carbon dioxide between the air and the bloodstream.

3. **Exploring Other Associations of Alveolus:**
- Apart from the lungs, the term "alveolus" is also associated with the bony sockets in which teeth are anchored. These sockets are known as the alveolar sockets or alveoli of the jawbone.

4. **Understanding the Structure of Alveolar Sockets:**
- The alveolar process is a ridge in the maxilla (upper jaw) and mandible (lower jaw) that contains the alveoli. Each alveolus is a cavity that holds the root of a tooth, secured by periodontal ligaments.

5. **Conclusion:**
- Therefore, besides the lungs, the term "alveolus" is also associated with the bony sockets of teeth, which are part of the skeletal system.

**Final Answer:**
The term "alveolus" is associated with the bony sockets of teeth in addition to the lungs.
