Epithelial Tissue MCQs: practice questions

Sample Epithelial Tissue multiple-choice questions from General Histology & Microscopy.

Which statement about simple epithelia is correct?
- A. Only superficial cells contact the basal lamina
- B. All cells contact the basal lamina
- C. They always contain multiple layers
- D. They are always keratinized
- E. They lack cell junctions
Which epithelial structure is most directly associated with E-cadherin and actin filaments?
- A. Hemidesmosome
- B. Gap junction
- C. Zonula adherens
- D. Tight junction only
- E. Desmosome
A tracheal biopsy shows nuclei at different levels, goblet cells, and cilia, but every cell contacts the basal lamina. Which diagnosis is most appropriate?
- A. Simple cuboidal epithelium
- B. Stratified squamous epithelium
- C. Transitional epithelium
- D. Pseudostratified ciliated columnar epithelium
- E. Stratified cuboidal epithelium
Which epithelial specialization provides direct electrical and metabolic communication between adjacent cells?
- A. Gap junction
- B. Tight junction
- C. Desmosome
- D. Hemidesmosome
- E. Focal adhesion
Which epithelial arrangement is most appropriate for rapid diffusion across a thin barrier?
- A. Stratified cuboidal
- B. Stratified columnar
- C. Transitional
- D. Pseudostratified
- E. Simple squamous
Which epithelial specialization has a typical 9+2 axoneme and is capable of active movement?
The superficial cells of relaxed transitional epithelium are characteristically:
A biopsy shows one layer of cells in which every cell contacts the basal lamina, but not every cell reaches the lumen. What is this epithelium?
A mutation affects connexin proteins. Which epithelial function is most directly impaired?
Which component is part of the basal lamina?
Which junction anchors an epithelial cell to the underlying basal lamina through intermediate filaments?
A renal epithelial cell has extensive basal membrane infoldings and many mitochondria. This arrangement most strongly suggests specialization for:
Which epithelium lines most blood vessels?
A defect in epithelial tight junctions would most directly impair:
Which junction most directly prevents paracellular movement between adjacent epithelial cells?
Which feature is characteristic of epithelial tissue?
A patient has an inherited disorder causing fragile skin because epithelial cells detach from the basement membrane. Which structure is most directly implicated?
What is the major structural role of the basement membrane beneath epithelium?
Which epithelial specialization is composed primarily of actin filaments and increases apical surface area?
Stereocilia are best described as:
Which structure helps maintain the distinct apical and basolateral membrane domains of epithelial cells?
Which structure is primarily responsible for strong cell-to-cell adhesion against mechanical stress?
Which cytoskeletal element is associated with desmosomes?
Which epithelial type is specialized to accommodate stretching of the urinary tract?
Which epithelial type is best adapted for protection against abrasion while retaining a moist surface?
