Question 1:

Which of the following functions is NOT associated with the skeletal system?

Explanation: The regulation of body temperature is primarily associated with the muscular and nervous systems, not the skeletal system. The skeletal system provides structural support, protects internal organs, and facilitates movement. Therefore, option D is correct.

Question 2:

Which of the following types of bones is responsible for the production of red and white blood cells?

Explanation: Flat bones, such as the bones of the skull and sternum, are responsible for the production of red and white blood cells. These bones contain bone marrow, which is the site of hematopoiesis. Therefore, option B is correct.

Question 3:

Which of the following is the primary function of ligaments?

Explanation: Ligaments are fibrous connective tissues that connect bone to bone. They provide stability and support to joints, limiting excessive movement and preventing dislocation. Therefore, option B is correct.

Question 4:

Which of the following is the correct order of bone cells from the initial formation of bone to its remodeling?

Explanation: The correct order of bone cells from the initial formation of bone to its remodeling is: Osteoblasts - Osteocytes - Osteoclasts. Osteoblasts are responsible for bone formation, osteocytes are mature bone cells that maintain bone tissue, and osteoclasts are involved in bone resorption and remodeling. Therefore, option C is correct.

Question 5:

Which of the following is a function of the muscular system?

Explanation: The primary function of the muscular system is the facilitation of movement. Muscles work together with bones and joints to produce both voluntary and involuntary movements. Therefore, option C is correct.
