ANSWERS /GRADE A+ ASSURED
Question 1
Which of the following is the most superior body region?
A) Plantar
B) Cranial
C) Caudal
D) Lumbar
E) Pedal
Correct Answer: B) Cranial
Rationale: Cranial refers to the skull or head end of the body, which is the most superior
(uppermost) region.
Question 2
What is the primary function of the mitochondria in a cell?
A) Protein synthesis
B) Lipid storage
C) ATP production
D) Waste disposal
E) Genetic information storage
Correct Answer: C) ATP production
Rationale: Mitochondria are known as the "powerhouses of the cell" because they are the
primary sites of ATP (adenosine triphosphate) synthesis through cellular respiration.
Question 3
Which type of tissue is characterized by an extracellular matrix and provides support, binds
tissues together, and protects organs?
A) Epithelial tissue
B) Connective tissue
C) Muscle tissue
D) Nervous tissue
E) Adipose tissue
Correct Answer: B) Connective tissue
Rationale: Connective tissue is diverse but commonly features a prominent extracellular
matrix that supports, binds, and protects other tissues and organs.
Question 4
Which of the following is the correct anatomical term for the "shin bone"?
,A) Femur
B) Fibula
C) Tibia
D) Patella
E) Humerus
Correct Answer: C) Tibia
Rationale: The tibia is the larger of the two bones in the lower leg, commonly known as the
shin bone.
Question 5
What is the primary function of melanocytes in the epidermis?
A) To produce keratin.
B) To provide touch sensation.
C) To produce melanin, protecting against UV radiation.
D) To initiate immune responses.
E) To store fat.
Correct Answer: C) To produce melanin, protecting against UV radiation.
Rationale: Melanocytes produce melanin, a pigment that gives skin its color and absorbs
harmful ultraviolet (UV) radiation, protecting the skin.
Question 6
Which muscle action decreases the angle between two bones?
A) Extension
B) Abduction
C) Adduction
D) Flexion
E) Rotation
Correct Answer: D) Flexion
Rationale: Flexion is a movement that decreases the angle between articulating bones (e.g.,
bending the elbow).
Question 7
The central nervous system (CNS) consists of the:
A) Brain and spinal cord.
B) Spinal cord and peripheral nerves.
C) Brain and cranial nerves.
,D) Peripheral nerves and ganglia.
E) Autonomic and somatic nervous systems.
Correct Answer: A) Brain and spinal cord.
Rationale: The central nervous system (CNS) is composed of the brain and the spinal cord.
Question 8
Which body cavity contains the heart and lungs?
A) Abdominal cavity
B) Pelvic cavity
C) Cranial cavity
D) Thoracic cavity
E) Spinal cavity
Correct Answer: D) Thoracic cavity
Rationale: The thoracic cavity is superior to the diaphragm and contains the heart (within the
pericardial cavity) and lungs (within the pleural cavities).
Question 9
What is the primary function of osteoblasts?
A) To break down bone tissue.
B) To maintain bone tissue.
C) To build new bone tissue.
D) To produce red blood cells.
E) To store fat in bone marrow.
Correct Answer: C) To build new bone tissue.
Rationale: Osteoblasts are bone-forming cells responsible for synthesizing and secreting the
organic matrix and minerals that form new bone.
Question 10
Which of the following is a major function of the integumentary system?
A) Blood cell production
B) Hormone synthesis
C) Protection from environmental hazards
D) Vitamin K synthesis
E) Regulation of blood glucose
Correct Answer: C) Protection from environmental hazards
, Rationale: The integumentary system (skin, hair, nails) serves as a primary barrier against
pathogens, UV radiation, and physical trauma.
Question 11
The anatomical plane that divides the body into anterior and posterior portions is the:
A) Sagittal plane
B) Transverse plane
C) Frontal (coronal) plane
D) Midsagittal plane
E) Oblique plane
Correct Answer: C) Frontal (coronal) plane
Rationale: The frontal (coronal) plane divides the body or an organ into anterior (front) and
posterior (back) sections.
Question 12
What type of muscle tissue is striated, voluntary, and responsible for body movement?
A) Cardiac muscle
B) Smooth muscle
C) Skeletal muscle
D) Visceral muscle
E) Involuntary muscle
Correct Answer: C) Skeletal muscle
Rationale: Skeletal muscle tissue is characterized by its striations, its voluntary control, and its
role in moving bones and producing locomotion.
Question 13
Which part of a neuron typically receives incoming signals from other neurons?
A) Axon
B) Axon terminal
C) Myelin sheath
D) Dendrite
E) Cell body (soma)
Correct Answer: D) Dendrite
Rationale: Dendrites are specialized extensions of the neuron that receive synaptic input from
other neurons.
