Question 1: Which of the following best describes the anatomical position?
A. The body is prone with arms crossed over the chest.
B. The body is supine with arms extended laterally.
C. The body is erect with feet slightly apart and palms facing forward.
D. The body is seated with hands resting on the knees.
CORRECT ANSWER: C. The body is erect with feet slightly apart and palms
facing forward.
Rationale: The standard anatomical position is a reference posture in which the body is
upright, facing forward, feet parallel and slightly apart, and arms at the sides with palms
facing anteriorly. This position ensures consistent directional terminology.


Question 2: Which plane divides the body into equal right and left halves?
A. Sagittal plane
B. Parasagittal plane
C. Midsagittal plane
D. Transverse plane
CORRECT ANSWER: C. Midsagittal plane
Rationale: The midsagittal (median) plane runs vertically through the midline, dividing
the body into equal right and left halves. A sagittal plane is any vertical plane parallel to
the midline, while a parasagittal plane is off-center.


Question 3: Which directional term means "toward the front of the body"?
A. Posterior
B. Ventral
C. Dorsal
D. Superior

,CORRECT ANSWER: B. Ventral
Rationale: Ventral refers to the anterior or front side of the body. In human anatomy,
ventral and anterior are synonymous, while dorsal refers to the back.


Question 4: The heart is located in which cavity?
A. Cranial cavity
B. Abdominal cavity
C. Thoracic cavity
D. Pelvic cavity
CORRECT ANSWER: C. Thoracic cavity
Rationale: The thoracic cavity, enclosed by the rib cage, houses the heart, lungs,
esophagus, and major blood vessels. It is superior to the abdominal cavity and separated
from it by the diaphragm.


Question 5: What is the basic structural and functional unit of life?
A. Tissue
B. Organ
C. Cell
D. Molecule
CORRECT ANSWER: C. Cell
Rationale: The cell is the smallest unit that can carry out all processes of life, including
metabolism, growth, and reproduction. Tissues and organs are higher levels of
organization composed of many cells.


Question 6: Which organelle is responsible for ATP production?
A. Ribosome
B. Lysosome
C. Mitochondrion
D. Golgi apparatus
CORRECT ANSWER: C. Mitochondrion
Rationale: Mitochondria are the sites of aerobic cellular respiration, generating ATP
through oxidative phosphorylation. They are often called the "powerhouses" of the cell.


Question 7: Which type of tissue covers body surfaces and lines cavities?

,A. Nervous tissue
B. Muscular tissue
C. Connective tissue
D. Epithelial tissue
CORRECT ANSWER: D. Epithelial tissue
Rationale: Epithelial tissue forms continuous sheets that cover external surfaces and
line internal cavities and organs. It also forms glands and functions in protection,
absorption, and secretion.


Question 8: Which muscle type is under voluntary control?
A. Cardiac muscle
B. Smooth muscle
C. Skeletal muscle
D. Visceral muscle
CORRECT ANSWER: C. Skeletal muscle
Rationale: Skeletal muscle is striated and under conscious (voluntary) control, allowing
movement of the skeleton. Cardiac and smooth muscles are involuntary.


Question 9: What is the primary function of the integumentary system?
A. Movement
B. Protection
C. Digestion
D. Circulation
CORRECT ANSWER: B. Protection
Rationale: The integumentary system (skin, hair, nails, glands) provides a physical
barrier against pathogens, UV radiation, and dehydration. It also has roles in
temperature regulation and sensation.


Question 10: Which layer of skin contains stem cells for epidermal renewal?
A. Stratum corneum
B. Stratum basale
C. Stratum granulosum
D. Stratum lucidum
CORRECT ANSWER: B. Stratum basale
Rationale: The stratum basale is the deepest epidermal layer, composed of mitotically
active stem cells that produce keratinocytes, which migrate upward to replace shed cells.

, Question 11: Which bone type is the patella classified as?
A. Long bone
B. Short bone
C. Flat bone
D. Sesamoid bone
CORRECT ANSWER: D. Sesamoid bone
Rationale: The patella is a sesamoid bone, which develops within a tendon (the
quadriceps tendon) to protect it from excessive wear and increase mechanical leverage.


Question 12: What is the functional unit of compact bone?
A. Osteon
B. Trabecula
C. Lamella
D. Canaliculus
CORRECT ANSWER: A. Osteon
Rationale: The osteon (Haversian system) is the structural unit of compact bone,
consisting of concentric lamellae around a central Haversian canal containing blood
vessels and nerves.


Question 13: Which joint type allows for the greatest range of motion?
A. Fibrous joint
B. Cartilaginous joint
C. Synovial joint
D. Symphysis joint
CORRECT ANSWER: C. Synovial joint
Rationale: Synovial joints are freely movable (diarthroses) and contain synovial fluid
within a joint cavity. Examples include the shoulder, knee, and hip joints.


Question 14: Which type of muscle contraction occurs when the muscle length
changes while tension remains constant?
A. Isometric
B. Isotonic
C. Isokinetic
D. Concentric
