,Introduction
This comprehensive assessment is designed to evaluate mastery of fundamental and applied anatomy and
physiology concepts essential for clinical practice and academic success. The exam assesses critical knowledge
in skeletal identification, muscular function, nervous system organization, cardiovascular dynamics, and
multiple other body systems through a structured multiple-choice format. Questions incorporate scenario-
based clinical applications that emphasize real-world decision-making and professional reasoning.
Candidates will demonstrate their ability to integrate theoretical understanding with practical application,
ensuring readiness for advanced healthcare coursework and patient care environments where accurate
anatomical knowledge directly impacts diagnostic and therapeutic outcomes.
SECTION ONE: QUESTIONS 1–100
Question 1
Which bone is part of the appendicular skeleton rather than the axial skeleton?
A. Sternum
B. Femur
C. Vertebra
D. Occipital bone
🟢 B. Femur
,🔴 RATIONALE: The appendicular skeleton includes bones of the limbs and appendages (pectoral and pelvic
girdles), while the axial skeleton includes the skull, vertebral column, and thoracic cage. The femur is the thigh
bone and part of the leg, making it appendicular.
Question 2
A patient presents with weakness in extending the knee. Which muscle is most likely impaired?
A. Biceps brachii
B. Rectus abdominis
C. Quadriceps femoris
D. Gluteus maximus
🟢 C. Quadriceps femoris
🔴 RATIONALE: The quadriceps femoris is the primary muscle group responsible for knee extension. The
biceps brachii flexes the elbow, rectus abdominis flexes the trunk, and gluteus maximus extends the hip.
Question 3
Which part of the brain is primarily responsible for coordination and balance?
A. Cerebrum
B. Brainstem
C. Cerebellum
D. Thalamus
🟢 C. Cerebellum
, 🔴 RATIONALE: The cerebellum coordinates voluntary movements, maintains balance, and ensures muscle
coordination. The cerebrum handles higher cognitive functions, the brainstem manages vital functions, and the
thalamus relays sensory information.
Question 4
What is the functional unit of the kidney where blood filtration occurs?
A. Ureter
B. Nephron
C. Glomerulus
D. Renal pelvis
🟢 B. Nephron
🔴 RATIONALE: The nephron is the complete functional unit of the kidney that includes the glomerulus (for
filtration) and tubules (for reabsorption and secretion). While the glomerulus is part of filtration, the nephron is
the entire functional unit.
Question 5
Which muscle is responsible for smiling by elevating the corners of the mouth?
A. Orbicularis oculi
B. Zygomaticus
C. Diaphragm
D. Pectoralis major
