ANATOMY & PHYSIOLOGY | 75 VERIFIED Q&A | DETAILED
RATIONALES | PASS GUARANTEED – A+ GRADED
SECTION 1: INTRODUCTION TO ANATOMY & PHYSIOLOGY - Questions 1-10
Q1: Definition of Homeostasis
The student is reviewing homeostasis. Which statement best describes homeostasis?
A. The complete absence of change in the internal environment
B. The maintenance of relatively stable internal conditions despite external changes
C. The process of cell division and growth
D. The body's response to external stimuli only
Correct Answer: B
Rationale: Homeostasis is the body's ability to maintain relatively stable internal conditions within
narrow limits, even as external conditions change. It is a dynamic equilibrium, not a static state.
[100% CORRECT]
Q2: Negative Feedback Mechanism
The student is reviewing feedback mechanisms. Which of the following is an example of a negative
feedback mechanism?
A. Uterine contractions during childbirth
B. Blood clotting cascade
C. Regulation of blood glucose by insulin
D. Lactation in response to infant suckling
Correct Answer: C
Rationale: Negative feedback reverses a deviation from the set point. Insulin secretion in response
to elevated blood glucose lowers glucose back to normal. The other options are positive feedback.
[100% CORRECT]
Q3: Positive Feedback Mechanism
The student is reviewing feedback mechanisms. Positive feedback mechanisms:
A. Reverse the initial stimulus
B. Amplify the initial stimulus
C. Maintain a constant internal environment
D. Are the most common type of feedback
Correct Answer: B
,2
Rationale: Positive feedback amplifies the initial stimulus until a specific end point is reached. It is
less common than negative feedback. [100% CORRECT]
Q4: Anatomical Position
The student is reviewing anatomical position. In the standard anatomical position, the body is:
A. Lying face down
B. Standing erect with feet flat, arms at sides, palms facing forward
C. Sitting upright
D. Lying face up
Correct Answer: B
Rationale: The anatomical position is standing erect, feet flat on the floor, arms at the sides, and
palms facing forward (anteriorly). This is the reference for all anatomical descriptions. [100%
CORRECT]
Q5: Directional Terms – Superior
The student is reviewing directional terms. The nose is _____ to the mouth.
A. Inferior
B. Posterior
C. Superior
D. Lateral
Correct Answer: C
Rationale: Superior (cranial) means toward the head or upper part of the body. The nose is above
the mouth, so it is superior. [100% CORRECT]
Q6: Directional Terms – Proximal
The student is reviewing directional terms. The elbow is _____ to the wrist.
A. Distal
B. Proximal
C. Lateral
D. Medial
Correct Answer: B
Rationale: Proximal means closer to the point of attachment of a limb to the trunk. The elbow is
closer to the shoulder than the wrist, so it is proximal. [100% CORRECT]
Q7: Body Planes – Sagittal
, 3
The student is reviewing body planes. A plane that divides the body into equal right and left halves is
called a:
A. Frontal plane
B. Transverse plane
C. Midsagittal plane
D. Oblique plane
Correct Answer: C
Rationale: The midsagittal (median) plane passes vertically through the midline, dividing the body
into equal right and left halves. [100% CORRECT]
Q8: Body Planes – Transverse
The student is reviewing body planes. A transverse plane divides the body into:
A. Right and left portions
B. Anterior and posterior portions
C. Superior and inferior portions
D. Medial and lateral portions
Correct Answer: C
Rationale: A transverse (horizontal) plane divides the body into superior (upper) and inferior (lower)
portions. [100% CORRECT]
Q9: Body Cavities – Dorsal
The student is reviewing body cavities. The dorsal body cavity contains the:
A. Heart and lungs
B. Brain and spinal cord
C. Digestive organs
D. Reproductive organs
Correct Answer: B
Rationale: The dorsal body cavity contains the cranial cavity (brain) and the vertebral (spinal) cavity
(spinal cord). [100% CORRECT]
Q10: Serous Membranes
The student is reviewing serous membranes. The serous membrane that covers the lungs is the:
A. Parietal pleura
B. Visceral pleura
C. Parietal pericardium
D. Visceral peritoneum
Correct Answer: B
