ANAT 260 WCU Final Exam with answers in
bold and rationale graded A+
Section I: Anatomical Terminology & Body Organization (Questions 1–12)
1. Which anatomical plane divides the body into equal right and left halves?
A) Parasagittal plane
B) Transverse plane
C) Midsagittal (median) plane
D) Frontal (coronal) plane
Answer: C
Rationale: The midsagittal (median) plane is a vertical plane that divides the body into equal right
and left halves. A parasagittal plane divides the body into unequal right and left portions. -17
2. The ventral body cavity is divided into which two major subdivisions by the diaphragm?
A) Cranial and spinal cavities
B) Thoracic and abdominopelvic cavities
C) Pleural and pericardial cavities
D) Abdominal and pelvic cavities
Answer: B
Rationale: The ventral cavity is partitioned by the diaphragm into the thoracic cavity (superior) and
the abdominopelvic cavity (inferior). -17
3. Which directional term describes a structure located closer to the midline of the body?
A) Lateral
B) Proximal
C) Medial
D) Distal
Answer: C
Rationale: Medial refers to a position closer to the vertical midline. For example, the heart is medial
to the lungs. -17
4. Which serous membrane covers the external surface of the organs within a body cavity?
A) Parietal membrane
B) Visceral membrane
C) Peritoneal membrane
D) Pleural membrane
,Answer: B
Rationale: The visceral serous membrane covers the external surface of organs within the cavity,
while the parietal membrane lines the internal surface of body walls. -17
5. What is the basic structural and functional unit of all living organisms?
A) Tissue
B) Organ
C) Cell
D) Molecule
Answer: C
Rationale: The cell is the basic structural and functional unit of all living organisms. Tissues are
groups of similar cells working together. -17
6. Which level of structural organization consists of groups of similar cells that perform a common
function?
A) Chemical level
B) Cellular level
C) Tissue level
D) Organ level
Answer: C
Rationale: The tissue level consists of groups of similar cells and their extracellular matrix that work
together to perform a specific function. -6
7. Which body cavity contains the heart and lungs?
A) Abdominal cavity
B) Pelvic cavity
C) Thoracic cavity
D) Cranial cavity
Answer: C
Rationale: The thoracic cavity is the superior subdivision of the ventral cavity and contains the heart
and lungs (within the pericardial and pleural cavities). -17
8. Which directional term means "toward the feet" or "below"?
A) Superior
B) Inferior
C) Anterior
D) Posterior
Answer: B
Rationale: Inferior (caudal) means toward the feet or below a structure. Superior (cranial) means
toward the head. -17
,9. A cut made along the long axis of the body that divides it into anterior and posterior portions is
called a:
A) Sagittal section
B) Transverse section
C) Frontal (coronal) section
D) Oblique section
Answer: C
Rationale: A frontal (coronal) section divides the body into anterior (front) and posterior (back)
portions. -17
10. Which of the following is NOT a characteristic of epithelial tissue?
A) Cellularity
B) Avascularity
C) High regenerative capacity
D) Abundant extracellular matrix
Answer: D
Rationale: Epithelial tissue is characterized by high cellularity with minimal extracellular matrix,
avascularity, and high regenerative capacity. Abundant extracellular matrix is characteristic of
connective tissue. -6
11. The study of tissues is called:
A) Cytology
B) Histology
C) Embryology
D) Gross anatomy
Answer: B
Rationale: Histology is the microscopic study of tissue structure and function. -6
12. Which body cavity is lined by the peritoneum?
A) Thoracic cavity
B) Cranial cavity
C) Abdominopelvic cavity
D) Spinal cavity
Answer: C
Rationale: The abdominopelvic cavity is lined by the peritoneum, a serous membrane. The thoracic
cavity is lined by pleura and pericardium. -17
Section II: Histology & Cell Biology (Questions 13–30)
13. Which type of epithelium is best suited for diffusion and filtration?
A) Simple cuboidal
B) Simple squamous
, C) Stratified squamous
D) Simple columnar
Answer: B
Rationale: Simple squamous epithelium consists of a single layer of flattened cells, providing the
thinnest barrier for rapid diffusion and filtration. It is found in alveoli and glomerular capsules. -6
14. Which epithelial type is found lining the urinary bladder and allows for stretching?
A) Simple columnar
B) Stratified squamous
C) Transitional epithelium
D) Pseudostratified columnar
Answer: C
Rationale: Transitional epithelium is unique to the urinary system and can stretch as the bladder
fills. When relaxed, it appears stratified; when stretched, it appears as fewer layers. -19
15. The primary function of goblet cells in columnar epithelium is to:
A) Absorb nutrients
B) Secrete mucus
C) Provide structural support
D) Conduct electrical impulses
Answer: B
Rationale: Goblet cells are unicellular glands that secrete mucin, which hydrates to form mucus,
providing lubrication and protection. -6
16. Which connective tissue type is characterized by a gel-like matrix with all three fiber types and
is found in the dermis?
A) Adipose tissue
B) Areolar tissue
C) Dense regular connective tissue
D) Hyaline cartilage
Answer: B
Rationale: Areolar connective tissue contains fibroblasts, all three fiber types (collagen, elastic,
reticular), and a gel-like ground substance. It is found in the dermis and subcutaneous layer. -6
17. The most abundant type of cartilage in the body, found at the ends of long bones and in the
trachea, is:
A) Elastic cartilage
B) Fibrocartilage
C) Hyaline cartilage
D) Ossified cartilage
