Question 1

Which of the following best describes the main difference between epithelial and connective tissues in terms of their structure?

Accepted Answer

Epithelial tissues have closely packed cells with little extracellular matrix, while connective tissues have cells separated by abundant extracellular matrix.

Question 2

A patient presents with a tumor that originated from glandular epithelial cells. What is the most accurate term for this type of tumor?

Accepted Answer

Adenocarcinoma

Question 3

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-layered structure.

Question 4

Which of the following is a function of microvilli on the apical surface of epithelial cells?

Accepted Answer

Increasing surface area for absorption

Question 5

A tissue sample from the esophagus shows multiple layers of cells with flattened cells at the surface. Which type of epithelium is this?

Accepted Answer

Stratified squamous epithelium

Question 6

Which of the following best describes the role of mast cells in tissue injury?

Accepted Answer

They release histamine and other chemicals to stimulate inflammation.

Question 7

Which connective tissue cell type is responsible for breaking down the extracellular matrix?

Accepted Answer

Osteoclast

Question 8

A histology slide shows a tissue with parallel bundles of collagen fibers and fibroblasts. This tissue is most likely:

Accepted Answer

Dense regular connective tissue

Question 9

Which of the following best explains why cartilage heals poorly after injury?

Accepted Answer

Cartilage is avascular, so nutrients and cells required for repair are limited.

Question 10

Which type of membrane lines the inside of the digestive tract and secretes mucus?

Accepted Answer

Mucous membrane

Question 11

A patient has a genetic defect affecting the production of collagen fibers. Which tissue function would be most directly impaired?

Accepted Answer

Structural support and resistance to stretching in tendons and ligaments

Question 12

Which of the following is a characteristic unique to cardiac muscle tissue?

Accepted Answer

Intercalated discs with gap junctions

Question 13

Which of the following best describes the function of neuroglia in nervous tissue?

Accepted Answer

Support, nourish, and protect neurons

Question 14

A tissue sample from the urinary bladder shows cells that change shape from cuboidal to squamous when stretched. This tissue is:

Accepted Answer

Transitional epithelium

Question 15

Which of the following equations best represents the composition of a tissue?

Accepted Answer

$$ Tissue = Similar\ Cells + Extracellular\ Matrix $$

Question 16

Which of the following is a function of areolar (loose) connective tissue?

Accepted Answer

Packing material that fills spaces between organs

Question 17

A patient with a severe burn loses the outermost layer of skin. Which type of epithelium is primarily damaged?

Accepted Answer

Keratinized stratified squamous epithelium

Question 18

Which of the following best explains why scar tissue forms after a deep injury to skeletal muscle?

Accepted Answer

Skeletal muscle regenerates poorly, so fibroblasts produce dense collagenous tissue (scar tissue) instead.

Question 19

Which of the following best describes the function of cilia on epithelial cells lining the respiratory tract?

Accepted Answer

Propelling mucus and trapped particles out of the airways

Question 20

Which of the following is a correct sequence of events during the inflammatory response to tissue injury?

Accepted Answer

Mast cell activation, histamine release, vasodilation, increased permeability, swelling
