Section 1: Exam 1 – Introduction, Chemistry, Cells & Membrane Transport
Q1: The study of the structure of body parts and their relationships is called:
A. Physiology
B. Anatomy [CORRECT]
C. Histology only
D. Pathology only
Correct Answer: B
Rationale: Anatomy is the study of structure; physiology is the study of function.
Q2: Which level of organization is immediately above the tissue level?
A. Cellular
B. Organ [CORRECT]
C. Chemical
D. Organism
Correct Answer: B
Rationale: Tissues form organs; organs form organ systems.

Q3: Homeostasis is best defined as:
A. A static, unchanging internal environment
B. Maintenance of relatively stable internal conditions despite external changes
[CORRECT]
C. Only the regulation of body temperature
D. The complete absence of feedback mechanisms
Correct Answer: B
Rationale: Homeostasis is dynamic equilibrium of the internal environment.
Q4: In a negative feedback loop, the response:
A. Amplifies the original stimulus
B. Opposes or reduces the original stimulus [CORRECT]
C. Has no effect on the stimulus
D. Only occurs during disease
Correct Answer: B
Rationale: Negative feedback reverses the direction of the change to restore set point.
Q5: Which anatomical plane divides the body into left and right portions?
A. Frontal (coronal)
B. Transverse
C. Sagittal [CORRECT]
D. Oblique only
Correct Answer: C
Rationale: Sagittal planes divide left from right; midsagittal is exactly midline.

Q6: The term 'proximal' means:
A. Farther from the point of attachment
B. Closer to the point of attachment of a limb [CORRECT]
C. Toward the midline
D. Toward the surface
Correct Answer: B
Rationale: Proximal = nearer the trunk or point of origin; distal = farther away.
Q7: Which body cavity contains the heart and lungs?
A. Abdominopelvic only
B. Thoracic [CORRECT]
C. Cranial
D. Vertebral only
Correct Answer: B
Rationale: The thoracic cavity houses the lungs and heart (within the mediastinum).
Q8: An atom that has gained or lost electrons and carries a charge is a(n):
A. Isotope
B. Ion [CORRECT]
C. Molecule only
D. Compound only
Correct Answer: B
Rationale: Ions are charged atoms or groups of atoms.
