Summary Introduction

Introduction:

The skeletal system is the organ system that has bones, joints, and supporting tissue. They play a considerable role in the movement of a vertebrate organism. The skeletal system plays a pivotal role in the variousmechanisms of the body.

Answer to Problem 1CYR

Correct answer:

Primary storage site in the body for minerals such as sodium (Na) and potassium (K).

Explanation of Solution

Justification/explanationfor the correct answer:

Option (a) is primary storage site in the body for minerals sodium (Na) and potassium (K). This option is not a function of the skeletal system. Sodium in the body is found mostly in blood and other tissue fluids, whereas the potassium is found in the skeletal system. The skeletal system is considered as the storehouse of potassium. Hence, option (a) is correct.

Explanation for the incorrect answers:

Option (b) is location of red bone marrow, which produces a red cell. This is a correct option. The formation of red blood cells is called hematopoiesis. This process takes place in the red bone marrow, which is seen in the bone. So, it is an incorrect option.

Option (c) is storage of triglycerides in the yellow bone marrow. The yellow bone marrow present in the bone has adipocytes. These adipocytes have the capacity to store fat in the form of triglycerides. This is a function of the skeletal muscle. So, it is an incorrect option.

Option (d) is support and protection of the body and vital organs. The bone, which is a part of the skeletal system, is considered as the hardest component in the body of vertebrates. They can protect organs from external damage. They act as a shield around organs such as the brain and the heart. They also provide support to the body by handling the weight of the body. So, it is an incorrect option.

Option (e) is functions in movements as the site of attachment for skeletal muscle. There are skeletal muscles in our body, which have voluntary functions. They attach to the bones and enable movement by contraction. So, it is an incorrect option.

Hence, options (b), (c), (d), and (e) are incorrect.

Conclusion

Hence, it can be concluded that option (a) is incorrect because the primary storage of sodium is in the blood and tissue fluid. The other option is clearly the function of the skeletal muscles. The skeletal system has various functions such as protection, support, storage of fat, formation of blood cells, and movement.
