2. **Number of Bones**: The adult human skeleton typically consists of 206 bones. These bones are categorized into two main groups: the axial skeleton (which includes the skull, vertebral column, and rib cage) and the appendicular skeleton (which includes the limbs and pelvic girdle).

3. **Role of Cartilage**: In addition to bones, cartilage is also an important component of the skeleton. It provides flexibility and support in certain areas, such as joints and the rib cage.

4. **Shape of the Skeleton**: The overall shape of the human skeleton is described as S-shaped. This shape is crucial for maintaining balance and supporting the weight of the body.

5. **Evaluating the Options**: Given the options provided (J-shaped, M-shaped, L-shaped, S-shaped), we can analyze each:
- J-shaped: Incorrect
- M-shaped: Incorrect
- L-shaped: Incorrect
- S-shaped: Correct

6. **Conclusion**: Therefore, the correct answer regarding the shape of the human skeleton is S-shaped.
