ORIGINAL PRACTICE & REVIEW ASSESSMENT · NOT AN OFFICIAL OR SECURED EXAM
2026 BIOL 251 Module 3 Exam Review
Human Anatomy & Physiology I with Lab
68 Questions with Correct Answers, Rationales & High-Yield Review
This original, independently written practice assessment covers Module 3 of a BIOL 251–style Human Anatomy &
Physiology I course: the four primary tissue types (epithelial, connective, muscle, and nervous) and the stages of tissue
repair. It includes 68 questions in multiple formats — multiple choice, true/false, matching, and image-based
identification using all 10 supplied histology and diagram images — followed by a complete answer key, rationale for
every question, and a high-yield final review. This resource is an independent study aid created for exam preparation; it
is not an actual Portage Learning examination, proprietary question bank, or secured assessment, and no content has
been copied or reproduced from any copyrighted course material.
Questions: 68 · Image-Based Items: 14 · Figures: 10 (all 10 supplied images) · Modules: Epithelial (20) · Connective (18) · Muscle (13) ·
Nervous (8) · Repair (9)
Section I — Questions 1–68
Figures are placed immediately before the questions that reference them. Original labels (A, B, C, etc.) shown on each figure are
preserved exactly as supplied.
MODULE 3 — EPITHELIAL TISSUE
Question 1 [Multiple Choice]
Which of the following is a primary function shared by all epithelial tissues?
A. Contraction to generate movement
B. Storing long-term energy reserves
C. Producing antibodies
D. Covering body surfaces and lining cavities
Question 2 [Multiple Choice]
Epithelial polarity refers to the fact that epithelial cells have structurally and functionally distinct:
A. Left and right surfaces
B. Anterior and posterior surfaces
C. Apical and basal surfaces
D. Superior and inferior nuclei
Question 3 [Multiple Choice]
The basement membrane underlying epithelial tissue primarily functions to:
A. Generate new epithelial cells directly
B. Contract to move the epithelial layer
C. Produce mucus for lubrication
D. Anchor the epithelium to underlying connective tissue and filter materials passing between the layers

Question 4 [True / False]
True or False: Epithelial tissue has a strong capacity for regeneration because it often contains actively dividing
stem cells.
A. True
B. False
C. Only glandular epithelium can regenerate
D. Only stratified epithelium can regenerate
Question 5 [Multiple Choice]
Epithelial tissues are classified according to which two characteristics?
A. Vascularity and fiber type
B. Voluntary vs. involuntary control
C. Number of cell layers and cell shape
D. Presence of a nucleus and cell size
Figure 1 — Simple Epithelial Tissues (Panels A–C)
Question 6 [Diagram / Image-Based]
In Figure 1, panel B shows a single layer of roughly square-shaped cells. This tissue is best identified as:
A. Simple cuboidal epithelium
B. Simple squamous epithelium
C. Simple columnar epithelium
D. Stratified cuboidal epithelium
Question 7 [Multiple Choice]
, 3|Page
Simple squamous epithelium, shown as the thinnest, flattened cell layer, is best suited anatomically for which
location and function?
A. Stomach lining, for enzyme secretion
B. Skin surface, for protection against abrasion
C. Alveoli and capillary walls, for rapid diffusion and filtration
D. Bladder lining, for stretch accommodation
Figure 2 — Stratified and Pseudostratified Epithelia (Panels A–D)
Question 8 [Diagram / Image-Based]
In Figure 2, panel D shows tall cells with cilia at the apical surface and nuclei staggered at different heights,
giving a false impression of multiple layers. This tissue is:
A. Pseudostratified ciliated columnar epithelium
B. Stratified columnar epithelium
C. Transitional epithelium
D. Simple columnar epithelium
Question 9 [Multiple Choice]
The key structural difference between the keratinized and nonkeratinized forms of stratified squamous epithelium
shown in Figure 2 (panels A and B) is that the keratinized form has:
A. More layers of cells overall
B. Cilia at the apical surface
C. A surface layer of dead cells packed with keratin, while the nonkeratinized form retains living cells at the
surface
D. A secretory function absent in the nonkeratinized form
