Question 1

Which of the following best describes the main function and location of simple squamous epithelium?

Accepted Answer

Diffusion and filtration; found in air sacs of lungs and lining blood vessels

Question 2

A patient suffers a severe burn that destroys the epidermis and underlying connective tissue. Which tissue types are primarily affected?

Accepted Answer

Epithelial and connective tissue

Question 3

Which of the following statements about connective tissue is CORRECT?

Accepted Answer

It arises from mesenchyme and contains an abundant extracellular matrix.

Question 4

Which type of gland releases its product by cell rupture, and what is a classic example?

Accepted Answer

Holocrine; sebaceous (oil) glands

Question 5

A biopsy reveals tissue with closely packed bundles of collagen fibers running parallel to each other. Which tissue is this, and what is its primary function?

Accepted Answer

Dense regular connective tissue; resists tension in one direction

Question 6

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

Accepted Answer

Cartilage is avascular and nutrients must diffuse through the matrix.

Question 7

Which of the following is a key difference between endocrine and exocrine glands?

Accepted Answer

Endocrine glands are ductless and secrete hormones into the blood; exocrine glands secrete products onto body surfaces or into cavities.

Question 8

A tissue sample shows cells with a single layer of tall, closely packed cells with oval nuclei, many of which have microvilli and goblet cells. What is the most likely tissue type and its main function?

Accepted Answer

Simple columnar epithelium; absorption and secretion

Question 9

Which connective tissue type forms the internal framework that supports free blood cells in lymph nodes, the spleen, and bone marrow?

Accepted Answer

Reticular connective tissue

Question 10

Which of the following best describes the structure and function of intercalated discs in cardiac muscle?

Accepted Answer

They are specialized junctions in cardiac muscle that allow rapid transmission of electrical impulses.

Question 11

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

Accepted Answer

Connective tissue

Question 12

Which membrane lines body cavities that open to the outside and is typically moist due to mucus secretion?

Accepted Answer

Mucous membrane

Question 13

Which of the following is TRUE regarding the basement membrane in epithelial tissue?

Accepted Answer

It separates epithelial tissue from underlying connective tissue and consists of the basal and reticular lamina.

Question 14

Which of the following best describes the difference between simple and stratified epithelia?

Accepted Answer

Simple epithelia consist of a single layer of cells; stratified epithelia have two or more layers.

Question 15

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

Accepted Answer

$$n = 1$$ \Rightarrow$$ Simple epithelium; n$$ \geq 2$$ \Rightarrow$$ Stratified epithelium

Question 16

Which of the following best explains why adipose tissue is an efficient energy storage tissue?

Accepted Answer

Its cells (adipocytes) store triglycerides, which are energy-rich molecules.

Question 17

A tissue sample from the urinary bladder shows dome-shaped cells on the apical surface that flatten when stretched. What is this tissue, and what is its function?

Accepted Answer

Transitional epithelium; allows stretching as the bladder fills

Question 18

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

Accepted Answer

Support, protect, and insulate neurons

Question 19

Which of the following is a characteristic of serous membranes?

Accepted Answer

They always occur in pairs and secrete serous fluid to reduce friction.

Question 20

A patient presents with a torn tendon. Which connective tissue type is most likely damaged, and what is its main structural protein?

Accepted Answer

Dense regular connective tissue; collagen
