BIOD 151 – Module 4: Bone Function &
Skeletal System Questions and Answers
Bone Functions (1–7)
1. What is the primary function of bones?
✅ SUPPORT
Rationale: Bones provide the structural framework that supports the body.
2. Which function of bone protects vital organs?
✅ PROTECTION
Rationale: The skull protects the brain; ribs protect heart and lungs.
3. Bones act as levers for which system?
✅ MUSCULAR SYSTEM
Rationale: Muscles pull on bones to create movement.
4. Which mineral is stored in bone tissue?
✅ CALCIUM
Rationale: Bones store calcium and release it to maintain blood levels.
5. Which process occurs in red bone marrow?
✅ HEMATOPOIESIS
Rationale: Red marrow produces blood cells.
6. Yellow bone marrow primarily stores:
✅ FAT (ADIPOSE TISSUE)
Rationale: Yellow marrow serves as an energy reserve.
7. Which bone function helps regulate blood calcium levels?
✅ MINERAL STORAGE AND RELEASE
Rationale: Bones release calcium when blood levels drop.
Bone Classification (8–13)
, 8. Which type of bone is the femur?
✅ LONG BONE
Rationale: Long bones are longer than they are wide.
9. Which bones protect the brain?
✅ FLAT BONES
Rationale: Cranial bones are flat and protective.
10. Vertebrae are classified as:
✅ IRREGULAR BONES
Rationale: They have complex shapes.
11. Carpals are examples of:
✅ SHORT BONES
Rationale: Short bones are cube-shaped.
12. The patella is a:
✅ SESAMOID BONE
Rationale: It forms within a tendon.
13. Which bone type provides strength with minimal weight?
