Which of the following is NOT a function of the muscular system?

• A. Movement
• B. Joint stability
• C. Hormone production
• D. Posture maintenance

Answer: (C)

The muscular system is primarily responsible for several key functions that are crucial for the body's operation. Movement is a fundamental role, as muscles contract to facilitate various movements of the body and its parts, ranging from gross motions like walking to fine motor skills like typing. Maintaining posture is another critical function, as muscles engage to keep the body upright and stable against gravity. Additionally, muscles contribute to joint stability, supporting the joints to prevent excessive movements that could lead to injury. Hormone production, however, is not a function of the muscular system. While some muscle types, like skeletal muscle, can release certain signaling molecules (often referred to as myokines), the primary hormone-producing tissues are found in glands such as the endocrine system. This indicates that the muscular system's primary roles do not include generating hormones as a primary function, distinguishing it from the other listed capabilities. Thus, option C correctly identifies a function that is outside the scope of the muscular system.
