Q: Which of the following equations best represents the relationship between the number of cell layers ($$n) $$and the type of epithelial tissue?

$$n = 1$$ \implies \text{Simple epithelium}$

Question 1

A tissue sample from a patient's trachea shows a single layer of cells with varying heights, all attached to the basement membrane, and nuclei at different levels. Which type of epithelium is most likely present in this sample?

Accepted Answer

Pseudostratified columnar epithelium

Question 2

Which of the following best describes the main structural difference between simple columnar and stratified columnar epithelium?

Accepted Answer

Simple columnar has a single layer of tall cells, while stratified columnar has multiple layers with only the top layer being columnar

Question 3

A biopsy from the urinary bladder reveals an epithelium with dome-shaped surface cells that can change shape when stretched. What is the most likely type of epithelium?

Accepted Answer

Transitional epithelium

Question 4

Which connective tissue type is characterized by a large amount of extracellular matrix with visible collagen fibers running in parallel bundles, providing great tensile strength in one direction?

Accepted Answer

Dense regular connective tissue

Question 5

A histological slide shows large, round cells with nuclei pushed to the periphery and very little visible cytoplasm. Which tissue is most likely being observed?

Accepted Answer

Adipose tissue

Question 6

Which of the following best explains why simple squamous epithelium is found lining the alveoli of the lungs?

Accepted Answer

It allows for rapid diffusion of gases due to its thin, single layer of flat cells

Question 7

A tissue sample contains cells with visible striations, multiple nuclei per cell, and the cells are long and cylindrical. Which tissue type is this?

Accepted Answer

Skeletal muscle tissue

Question 8

Which of the following is a distinguishing feature of cardiac muscle tissue compared to skeletal muscle tissue?

Accepted Answer

Cardiac muscle cells are branched and connected by intercalated discs

Question 9

A patient presents with a torn tendon. Which type of connective tissue is most likely damaged?

Accepted Answer

Dense regular connective tissue

Question 10

Which of the following equations best represents the relationship between the number of cell layers ($$n) $$and the type of epithelial tissue?

Accepted Answer

$$n = 1$$ \implies 	ext{Simple epithelium}$

Question 11

Which tissue type would you expect to find in the walls of arteries, providing both strength and elasticity?

Accepted Answer

Elastic connective tissue

Question 12

A histological section shows a matrix with chondrocytes in lacunae and a glassy, smooth appearance. Which tissue is this?

Accepted Answer

Hyaline cartilage

Question 13

Which of the following best describes the function of areolar connective tissue?

Accepted Answer

Supports and binds other tissues, holds body fluids, and defends against infection

Question 14

A tissue sample from the dermis of the skin shows collagen fibers running in many different directions. Which type of connective tissue is this?

Accepted Answer

Dense irregular connective tissue

Question 15

Which of the following best explains why stratified squamous epithelium is found in the esophagus?

Accepted Answer

It provides protection against abrasion from food particles

Question 16

A tissue sample shows fibers forming a mesh-like network that supports cells in lymph nodes and the spleen. Which tissue is this?

Accepted Answer

Reticular connective tissue

Question 17

Which of the following is a key difference between smooth muscle tissue and skeletal muscle tissue?

Accepted Answer

Smooth muscle tissue is involuntary and lacks striations

Question 18

A patient with a genetic defect in collagen synthesis is most likely to have problems with which tissue type?

Accepted Answer

Connective tissue

Question 19

Which of the following best describes the function of pseudostratified ciliated columnar epithelium in the respiratory tract?

Accepted Answer

Secretes mucus and moves particles out of the airways via cilia

Question 20

A tissue sample from the heart shows branching cells with striations and intercalated discs. Which tissue is this?

Accepted Answer

Cardiac muscle tissue
