Question 1

Which of the following best describes the primary function of epithelial tissue in the human body?

Accepted Answer

Covering surfaces and lining passageways

Question 2

A biopsy reveals a tissue sample with cells tightly packed together, forming a continuous sheet with an apical and basal surface, and no visible blood vessels. Which tissue type is most likely being observed?

Accepted Answer

Epithelial tissue

Question 3

Which of the following is NOT a characteristic of epithelial tissue?

Accepted Answer

Contains abundant protein fibers in a ground substance

Question 4

A gland that releases its secretions into the bloodstream rather than through a duct is classified as:

Accepted Answer

Endocrine

Question 5

Which of the following best explains why epithelial tissues are highly regenerative?

Accepted Answer

They are exposed to frequent damage and must replace lost or damaged cells quickly.

Question 6

Which type of epithelial tissue would be best suited for rapid diffusion of gases in the lungs?

Accepted Answer

Simple squamous epithelium

Question 7

A patient suffers a burn that destroys the cutaneous membrane. Which of the following is a direct consequence of this injury?

Accepted Answer

Increased risk of dehydration and infection

Question 8

Which of the following best describes the difference between serous and mucous membranes?

Accepted Answer

Serous membranes are double-walled and secrete a watery fluid, while mucous membranes line passageways that open to the exterior and secrete mucus.

Question 9

Which of the following cell junctions would be most important in preventing leakage of digestive enzymes between cells lining the stomach?

Accepted Answer

Tight junctions

Question 10

A tissue sample contains cells embedded in a matrix with abundant collagen fibers and a gel-like ground substance. Which type of tissue is this most likely to be?

Accepted Answer

Connective tissue

Question 11

Which of the following best explains the function of adipose tissue in the body?

Accepted Answer

Providing insulation and energy storage

Question 12

A patient with a genetic defect in collagen production would most likely have problems with which tissue type?

Accepted Answer

Connective tissue

Question 13

Which of the following is a function of reticular connective tissue?

Accepted Answer

Providing a framework for soft organs such as the spleen and lymph nodes

Question 14

Which of the following best describes the role of Schwann cells in nervous tissue?

Accepted Answer

They create myelin to insulate axons.

Question 15

During wound healing, which cell type is primarily responsible for laying down new collagen fibers in the damaged area?

Accepted Answer

Fibroblasts

Question 16

Which of the following best explains why cartilage heals more slowly than other tissues?

Accepted Answer

Cartilage is avascular and relies on diffusion for nutrient delivery.

Question 17

A patient presents with a disorder affecting the synovial membranes. Which of the following symptoms would most likely be observed?

Accepted Answer

Pain and reduced mobility in joints

Question 18

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 19

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

Accepted Answer

They form the blood-brain barrier for protection.

Question 20

A tissue sample is observed to have cells that are excitable, capable of generating action potentials, and are supported by smaller cells that do not conduct impulses. Which tissue is being described?

Accepted Answer

Nervous tissue
