Question 1: Which of the following levels of structural organization is the most
complex?
A) Tissue level
B) Cellular level
C) Chemical level
D) Organ system level
Rationale: The hierarchy goes from chemical to cellular, tissue, organ, organ system,
and finally the organism level. Organ systems are composed of multiple organs
working together.
Question 2: What type of feedback loop amplifies a stimulus to push a physiological
variable away from its baseline?
A) Negative feedback
B) Positive feedback
C) Neutral feedback
D) Inhibitory feedback
Rationale: Positive feedback mechanisms enhance or accelerate the original
stimulus, pushing the variable further from its normal value until a specific event or
outcome occurs, such as childbirth or blood clotting.
Question 3: Which anatomical plane divides the body into equal or unequal left and
right sides?
A) Sagittal plane
B) Frontal plane
C) Coronal plane
D) Transverse plane
,2|Page
Rationale: A sagittal plane runs vertically and divides the body into left and right
sides. If it is exactly in the middle, it is called a midsagittal or median plane.
Question 4: The patellar region is located on which surface of the body?
A) Posterior
B) Lateral
C) Anterior
D) Superior
Rationale: The patellar region refers to the kneecap, which is located on the anterior
(front) aspect of the lower limb.
Question 5: Which cavity contains the lungs and heart?
A) Abdominal cavity
B) Pelvic cavity
C) Thoracic cavity
D) Cranial cavity
Rationale: The thoracic cavity is located above the diaphragm and houses the
pleural cavities (lungs) and the mediastinum/pericardial cavity (heart).
Question 6: Which organelle is known as the powerhouse of the cell because it
generates most of the cell's ATP?
A) Lysosome
B) Mitochondrion
C) Golgi apparatus
D) Ribosome
Rationale: Mitochondria perform aerobic cellular respiration, which converts nutrients
into adenosine triphosphate (ATP), the primary energy currency of the cell.
Question 7: What type of transport requires ATP to move a substance against its
concentration gradient?
A) Facilitated diffusion
B) Simple diffusion
C) Osmosis
D) Primary active transport
Rationale: Active transport uses cellular energy (ATP) to pump molecules or ions
uphill from an area of lower concentration to an area of higher concentration.
Question 8: Which tissue type is specialized to cover body surfaces, line internal
cavities, and form glands?
A) Epithelial tissue
B) Connective tissue
C) Muscle tissue
D) Nervous tissue
Rationale: Epithelial tissue is tightly packed with cells and acts as a protective
barrier, absorption surface, or secretory structure covering the outside of the body
and lining organs.
Question 9: What type of epithelium is found lining the urinary bladder, allowing it to
stretch and distend?
A) Simple squamous epithelium
B) Stratified columnar epithelium
C) Transitional epithelium
D) Pseudostratified epithelium
,3|Page
Rationale: Transitional epithelium is a specialized stratified tissue where cells
change shape from round to flat as the organ fills with fluid and stretches.
Question 10: Which type of connective tissue contains a fluid extracellular matrix
called plasma?
A) Cartilage
B) Blood
C) Adipose
D) Dense regular tissue
Rationale: Blood is a fluid connective tissue. Its extracellular matrix is plasma, which
suspends formed elements like red blood cells, white blood cells, and platelets.
Question 11: What is the primary pigment responsible for skin, hair, and eye color?
A) Carotene
B) Hemoglobin
C) Melanin
D) Keratin
Rationale: Melanin is produced by melanocytes in the stratum basale of the
epidermis and protects keratinocyte DNA from ultraviolet (UV) radiation.
Question 12: Which layer of the epidermis is found only in thick skin, such as the
palms of the hands and soles of the feet?
A) Stratum basale
B) Stratum spinosum
C) Stratum lucidum
D) Stratum corneum
Rationale: The stratum lucidum is a thin, clear layer of dead keratinocytes found
exclusively in thick skin to provide extra protection against friction.
Question 13: What structural unit of compact bone consists of concentric rings of
bone matrix surrounding a central canal?
A) Trabecula
B) Canaliculus
C) Osteon
D) Lacuna
Rationale: An osteon (or Haversian system) is the fundamental functional and
structural unit of mature compact bone.
Question 14: Which type of bone cell is responsible for breaking down bone matrix to
release calcium into the blood?
A) Osteoblast
B) Osteocyte
C) Osteoclast
D) Osteogenic cell
Rationale: Osteoclasts are large, multinucleated cells derived from white blood cell
lineages that resorb (dissolve) bone matrix during remodeling and calcium
homeostasis.
Question 15: Which bone is classified as part of the axial skeleton?
A) Sternum
B) Femur
C) Scapula
D) Clavicle
, 4|Page
Rationale: The axial skeleton forms the central axis of the body and includes the
skull, vertebral column, ribs, and sternum. The limb bones belong to the
appendicular skeleton.
Question 16: What type of joint is freely movable and contains a fluid-filled cavity?
A) Fibrous joint
B) Cartilaginous joint
C) Synovial joint
D) Synarthrosis joint
Rationale: Synovial joints are characterized by a joint cavity containing synovial fluid,
allowing a wide range of movements (diarthroses).
Question 17: Which specialized plasma membrane of a muscle fiber propagates
action potentials?
A) Sarcoplasm
B) Sarcolemma
C) Sarcoplasmic reticulum
D) T-tubule
Rationale: The sarcolemma is the specific name given to the excitable cell
membrane of a skeletal or cardiac muscle cell.
Question 18: During skeletal muscle contraction, calcium ions bind to which
regulatory protein?
A) Troponin
B) Tropomyosin
C) Myosin
D) Actin
Rationale: Calcium binds to troponin, causing a conformational change that pulls
tropomyosin away from the active binding sites on actin filaments.
Question 19: What thin filament protein physically covers the myosin-binding sites on
actin when a muscle is at rest?
A) Titin
B) Troponin
C) Tropomyosin
D) Dystrophin
Rationale: Tropomyosin blocks the active sites on actin in a resting muscle fiber,
preventing cross-bridge formation until calcium is present.
Question 20: Which division of the nervous system consists exclusively of the brain
and spinal cord?
A) Peripheral nervous system
B) Central nervous system
C) Autonomic nervous system
D) Somatic nervous system
Rationale: The central nervous system (CNS) is the integration and command
center, composed solely of the brain and the spinal cord.
Question 21: Which part of a neuron typically receives incoming signals from other
neurons?
A) Axon
B) Axon hillock
C) Dendrite
