(100% CORRECT ANSWERS A+ GRADED
1. Which level of structural organization is the smallest and most
fundamental unit of matter?
A) Cellular
B) Tissue
C) Chemical
D) Organ
Answer: C) Chemical
Explanation: The chemical level, which includes atoms and molecules, is
the most basic level of structural organization. Cells are composed of
molecules, tissues are composed of cells, and organs are composed of
tissues, making the chemical level the foundational unit.
2. The sum of all chemical processes that occur in the body is known as:
A) Homeostasis
B) Anabolism
,2|Page
C) Catabolism
D) Metabolism
Answer: D) Metabolism
Explanation: Metabolism is the broad term that encompasses all
chemical reactions within the body. Anabolism refers specifically to
synthesis reactions, and catabolism refers to decomposition reactions.
Homeostasis is the maintenance of stable internal conditions.
3. Which feedback system reinforces a change in a controlled condition,
often leading to a cascading effect?
A) Negative feedback
B) Positive feedback
C) Feed-forward control
D) Inhibitory feedback
Answer: B) Positive feedback
Explanation: Positive feedback mechanisms amplify the initial stimulus,
moving the variable further away from its set point. A classic example is
the release of oxytocin during childbirth to increase uterine
contractions. Negative feedback reverses a change to maintain stability.
4. The anatomical term "crural" refers to which body region?
A) Arm
B) Head
C) Leg
,3|Page
D) Neck
Answer: C) Leg
Explanation: "Crural" specifically describes the anterior aspect of the
leg, particularly the shin. "Brachial" refers to the arm, "cephalic" to the
head, and "cervical" to the neck.
5. The heart is located within which body cavity?
A) Cranial
B) Abdominopelvic
C) Pleural
D) Pericardial
Answer: D) Pericardial
Explanation: The heart is enclosed by a protective membrane called the
pericardium, and the space it occupies is the pericardial cavity. The
pleural cavities house the lungs, and the abdominopelvic cavity
contains the digestive and reproductive organs.
6. A plane that divides the body into anterior and posterior portions is
called a:
A) Transverse plane
B) Midsagittal plane
C) Coronal plane
D) Oblique plane
Answer: C) Coronal plane
, 4|Page
Explanation: A coronal, or frontal, plane divides the body or an organ
into front (anterior) and back (posterior) sections. A transverse plane
divides into superior and inferior parts, while a midsagittal plane
divides into equal left and right halves.
7. Which directional term means "farther from the midline of the
body"?
A) Medial
B) Proximal
C) Lateral
D) Superior
Answer: C) Lateral
Explanation: Lateral describes a position that is farther from the body's
midline. Medial means nearer to the midline. Proximal and distal
describe limb position relative to the trunk, and superior means toward
the head.
8. The serous membrane that lines the walls of the abdominopelvic
cavity is the:
A) Visceral peritoneum
B) Parietal pleura
C) Parietal peritoneum
D) Visceral pleura
Answer: C) Parietal peritoneum
