Which of the following is NOT a role of the skeletal system?

The role of producing hormones is indeed not a primary function of the skeletal system. While the skeletal system is critical for supporting the body, providing structure, and protecting vital organs, it does not directly participate in hormone production. Instead, the primary functions of the skeletal system include supporting body weight, serving as a reservoir for mineral storage, facilitating movement through the attachment of muscles, and protecting organs such as the heart and lungs.

Bone marrow, located within certain bones, primarily functions in the production of blood cells (hematopoiesis) and acts as a storage site for fat, further emphasizing the critical physiological roles the skeletal system plays. In contrast, hormone production is largely the responsibility of the endocrine system, involving glands such as the thyroid, pituitary, and adrenal glands. Thus, the assertion that the skeletal system produces hormones does not align with the established physiological roles of this system.
