Comprehensive 110-Question Original Actual Exam Set | 2026/2027
Introduction
This 2026/2027 comprehensive 110-question actual exam set provides original questions covering Bone Tissue
and Histology, the Axial Skeleton including skull, vertebral column, and thoracic cage, the Appendicular Skeleton
including pectoral girdle, upper limbs, pelvic girdle, and lower limbs, and Joints and Articulations with structural
and functional classifications. The content is designed to reinforce official Anatomy and Physiology course
objectives for actual exam readiness and academic success by strengthening histological recognition, bone
landmark identification, skeletal relationships, joint classification, and evidence-based anatomical nomenclature.
Each item includes Verified Questions with concise rationales grounded in anatomy and physiology sources such
as Marieb, Saladin, Tortora, current histological standards, and accepted anatomical terminology.
Domain: Bone Tissue and Histology
1. Which microscopic unit is the basic structural unit of compact bone?
A. Osteon
B. A structure from a different skeletal region
C. A soft tissue feature not made of bone
D. A name that does not match accepted anatomical terminology
Correct Answer: A
Rationale: Compact bone is organized into osteons, or Haversian systems, built around central canals.
2. Which canal carries blood vessels and nerves through the center of an osteon?
A. A structure from a different skeletal region
B. Central canal
C. A soft tissue feature not made of bone
D. A name that does not match accepted anatomical terminology
Correct Answer: B
Rationale: The central canal contains vessels and nerves that support osteocytes in surrounding lamellae.
3. Which small spaces house mature bone cells within the matrix?
A. A structure from a different skeletal region
B. A soft tissue feature not made of bone
C. Lacunae
D. A name that does not match accepted anatomical terminology
Correct Answer: C
Rationale: Osteocytes reside in lacunae between concentric lamellae.
4. Which tiny channels connect lacunae and permit nutrient exchange between osteocytes?
A. A structure from a different skeletal region
B. A soft tissue feature not made of bone

, C. A name that does not match accepted anatomical terminology
D. Canaliculi
Correct Answer: D
Rationale: Canaliculi allow cell processes to communicate and exchange materials through mineralized
matrix.
5. Which bone cell is primarily responsible for forming new bone matrix?
A. Osteoblast
B. A structure from a different skeletal region
C. A soft tissue feature not made of bone
D. A name that does not match accepted anatomical terminology
Correct Answer: A
Rationale: Osteoblasts secrete osteoid and participate in mineralization.
6. Which bone cell is responsible for resorbing mineralized bone?
A. A structure from a different skeletal region
B. Osteoclast
C. A soft tissue feature not made of bone
D. A name that does not match accepted anatomical terminology
Correct Answer: B
Rationale: Osteoclasts are large multinucleated cells that dissolve mineral and degrade matrix.
7. Which mature bone cell maintains bone matrix after becoming trapped in lacunae?
A. A structure from a different skeletal region
B. A soft tissue feature not made of bone
C. Osteocyte
D. A name that does not match accepted anatomical terminology
Correct Answer: C
Rationale: Osteocytes monitor and maintain bone tissue after osteoblasts become embedded.
8. Which unmineralized organic material is secreted before bone hardens?
A. A structure from a different skeletal region
B. A soft tissue feature not made of bone
C. A name that does not match accepted anatomical terminology
D. Osteoid
Correct Answer: D
Rationale: Osteoid is the collagen-rich organic matrix that later mineralizes.
9. Which mineral crystals give bone much of its hardness?
A. Hydroxyapatite
B. A structure from a different skeletal region
C. A soft tissue feature not made of bone
D. A name that does not match accepted anatomical terminology
Correct Answer: A
Rationale: Hydroxyapatite calcium phosphate crystals provide compressive strength.
10. Which protein fiber gives bone tensile strength and flexibility?
A. A structure from a different skeletal region
B. Collagen
C. A soft tissue feature not made of bone
D. A name that does not match accepted anatomical terminology
Correct Answer: B
Rationale: Collagen resists pulling forces and contributes flexibility to bone.
11. Which membrane covers the outer surface of bone except at articular cartilage?
A. A structure from a different skeletal region
B. A soft tissue feature not made of bone

, C. Periosteum
D. A name that does not match accepted anatomical terminology
Correct Answer: C
Rationale: The periosteum contains osteogenic cells, vessels, nerves, and anchoring fibers.
12. Which membrane lines medullary cavities and internal bone surfaces?
A. A structure from a different skeletal region
B. A soft tissue feature not made of bone
C. A name that does not match accepted anatomical terminology
D. Endosteum
Correct Answer: D
Rationale: The endosteum lines internal spaces and contains cells involved in remodeling.
13. Which bone tissue is arranged as trabeculae with marrow-filled spaces?
A. Spongy bone
B. A structure from a different skeletal region
C. A soft tissue feature not made of bone
D. A name that does not match accepted anatomical terminology
Correct Answer: A
Rationale: Spongy bone has trabeculae that align with stress while reducing weight.
14. Which region of a long bone is the shaft?
A. A structure from a different skeletal region
B. Diaphysis
C. A soft tissue feature not made of bone
D. A name that does not match accepted anatomical terminology
Correct Answer: B
Rationale: The diaphysis is the elongated shaft surrounding the medullary cavity.
15. Which region of a long bone is located at each expanded end?
A. A structure from a different skeletal region
B. A soft tissue feature not made of bone
C. Epiphysis
D. A name that does not match accepted anatomical terminology
Correct Answer: C
Rationale: Epiphyses form the proximal and distal ends of long bones.
16. Which layer covers the end of a long bone at a synovial joint?
A. A structure from a different skeletal region
B. A soft tissue feature not made of bone
C. A name that does not match accepted anatomical terminology
D. Articular cartilage
Correct Answer: D
Rationale: Hyaline articular cartilage reduces friction and absorbs compression.
17. Which process describes bone formation within a hyaline cartilage model?
A. Endochondral ossification
B. A structure from a different skeletal region
C. A soft tissue feature not made of bone
D. A name that does not match accepted anatomical terminology
