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

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

Question 1

Which of the following is a key structural characteristic of epithelial tissue that distinguishes it from connective tissue?

Accepted Answer

It is composed almost entirely of cells with minimal extracellular material.

Question 2

A patient presents with a wound on the skin. Which type of epithelial tissue is most likely to be involved in the initial protection and why?

Accepted Answer

Stratified squamous epithelium, because it provides multiple layers for protection.

Question 3

Which of the following best describes the difference between exocrine and endocrine glands?

Accepted Answer

Exocrine glands use ducts to carry products to epithelial surfaces, while endocrine glands secrete directly into surrounding tissue fluid.

Question 4

Which apical surface feature of epithelial cells is responsible for moving mucus and other substances across the cell surface?

Accepted Answer

Cilia

Question 5

A researcher is studying the basement membrane of epithelial tissue. Which component is produced by epithelial cells and acts as a selective filter?

Accepted Answer

Basal lamina

Question 6

Which connective tissue cell type is primarily responsible for secreting the extracellular matrix in cartilage?

Accepted Answer

Chondroblasts

Question 7

Which type of connective tissue is best suited for resisting tension due to its abundance of collagen fibers?

Accepted Answer

Dense regular connective tissue

Question 8

A newborn is found to have a high amount of brown adipose tissue. What is the primary function of this tissue in infants?

Accepted Answer

Producing heat to aid thermoregulation

Question 9

Which of the following is unique about blood compared to other connective tissue classes?

Accepted Answer

Its extracellular matrix is not produced by the cells within the tissue.

Question 10

Which muscle tissue type contains intercalated discs and is responsible for involuntary contractions of the heart?

Accepted Answer

Cardiac muscle tissue

Question 11

Which cell type in nervous tissue is responsible for generating and conducting nerve impulses?

Accepted Answer

Neurons

Question 12

During the inflammatory response to injury, which chemical increases the permeability of capillaries, leading to edema?

Accepted Answer

Histamine

Question 13

Arrange the following steps in the correct order for tissue repair after injury: organization, regeneration, inflammation, edema, fibrosis.

Accepted Answer

Inflammation, edema, organization, fibrosis, regeneration

Question 14

Which type of epithelial tissue is best adapted for rapid diffusion and is commonly found lining blood vessels and alveoli?

Accepted Answer

Simple squamous epithelium

Question 15

A gland is classified as 'compound tubuloalveolar.' What does this mean about its structure?

Accepted Answer

It has branched ducts and both tubular and spherical secretory units.

Question 16

Which protein fiber in connective tissue is most responsible for allowing tissues to recoil after being stretched?

Accepted Answer

Elastic fibers

Question 17

Which of the following formulas best represents the relationship between the number of cell layers ($$n) $$and the type of epithelium?

Accepted Answer

$$n = 1$$ ightarrow 	ext{Simple epithelium}$

Question 18

A tissue sample contains cells with fingerlike extensions on their apical surface, maximizing surface area for absorption. Which structure is most likely present?

Accepted Answer

Microvilli

Question 19

Which connective tissue subtype is most likely to be found surrounding small nerves and blood vessels, supporting and binding other tissues?

Accepted Answer

Areolar connective tissue

Question 20

A patient with chronic inflammation is found to have excessive scar tissue formation. Which process is responsible for this proliferation of scar tissue?

Accepted Answer

Fibrosis
