Question

Which student statement regarding the function of the skeletal system requires clarification from the instructor?

Answers

  1. “The brain is protected by the skull.”
    • Rationale:

      This student statement is true as the brain is protected by the bones of the skull; therefore, no clarification from the instructor is required.

  2. “The lungs are protected by the bony rib cage.”
    • Rationale:

      This student statement is true as the lungs are protected by the bony rib cage; therefore, no clarification from the instructor is required.

  3. “The bone marrow is responsible for collagen formation.”
    • Rationale:

      This student statement requires clarification from the instructor. The bone marrow is responsible for the formation of RBCs, not collagen.

  4. “The bones, at the joints, must have full range of motion for bodily movements.”
    • Rationale:

      This student statement is true as the bones, at the joints, must have full range of movement for bodily movements to occur; therefore, no clarification from the instructor is required.

Overview

The skeletal system has several different functions within the human body.

Explanation

Learning Outcomes

The primary function of the skeletal system is protection. The bones of the skull protect the brain while the bony rib cage protects the lungs. In addition, the bones also provide range of movement when working in conjunction with the joints of the body. The bone marrow is responsible for red blood cells (RBCS), not collagen formation; therefore, this student statement requires clarification from the instructor as this is not a function of the skeletal system.

Test Taking Tip

The terminology, “requires clarification” indicates that the correct choice for this question is a false student statement regarding the skeletal system.
