Section 1: General Anatomy & Physiology Terminology (15 Questions)
**Question 1.**
Which term describes the body's ability to maintain a stable internal
environment despite external changes?
A) Metabolism
B) Homeostasis
C) Anabolism
D) Catabolism
**Answer:** B
**Rationale:** Homeostasis is the maintenance of a relatively stable
internal environment. Metabolism (A) includes all chemical reactions.
Anabolism (C) is building molecules; catabolism (D) is breaking down
molecules.

**Question 2.**
The plane that divides the body into equal left and right halves is called:
A) Coronal plane
B) Transverse plane
C) Sagittal plane
,3|Page
D) Midsagittal plane
**Answer:** D
**Rationale:** The midsagittal (median) plane divides the body into
equal left and right halves. Sagittal plane (C) divides into left and right
but not necessarily equal halves.

**Question 3.**
Which directional term means "toward the back of the body"?
A) Anterior
B) Ventral
C) Posterior
D) Superior
**Answer:** C
**Rationale:** Posterior (dorsal) means toward the back of the body.
Anterior/ventral (A,B) means toward the front. Superior (D) means
above.

**Question 4.**
The term "proximal" means:
A) Away from the point of attachment
B) Closer to the point of attachment
C) Toward the midline
D) Away from the midline
**Answer:** B
**Rationale:** Proximal means closer to the point of attachment to the
trunk. Distal (A) means farther away. Medial (C) means toward midline;
lateral (D) means away from midline.
