Question

Which of the following may cause skeletal variations?

a. inadequate supply of calcium and vitamin D
b. mechanical stress
c. age
d. all the above may cause skeletal variations

Answer 1

Skeletal variations can be caused by inadequate supply of calcium and vitamin D, mechanical stress, and aging.

Step-by-step explanation:

Skeletal variations may be caused by a combination of factors, including:

1. Inadequate supply of calcium and vitamin D: This can lead to abnormally weak bones that are prone to breakage and fractures, possibly resulting in a shorter stature.
2. Mechanical stress: It stimulates the deposition of mineral salts and collagen fibers within bones.
3. Age: As individuals age, they may experience abnormal bone formation, such as thinner and/or shorter bones.
