Question 1

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

Accepted Answer

Covering body surfaces and lining internal cavities to provide protection, absorption, and secretion

Question 2

A biopsy reveals a tissue sample with tightly packed cells, little extracellular matrix, and the presence of cilia on the apical surface. Which type of tissue is most likely being observed?

Accepted Answer

Epithelial tissue

Question 3

Which of the following is NOT a characteristic common to all types of epithelial tissue?

Accepted Answer

Presence of abundant collagen fibers in the extracellular matrix

Question 4

A patient presents with a disorder affecting the absorption of nutrients in the small intestine. Which epithelial tissue type is most likely involved?

Accepted Answer

Simple columnar epithelium

Question 5

Which of the following best distinguishes endocrine glands from exocrine glands?

Accepted Answer

Endocrine glands secrete hormones directly into the bloodstream, while exocrine glands release their products onto epithelial surfaces via ducts.

Question 6

Which of the following connective tissue types is primarily responsible for storing energy in the form of triglycerides?

Accepted Answer

Adipose tissue

Question 7

A tendon is composed mainly of which type of connective tissue, and what is its primary function?

Accepted Answer

Dense regular connective tissue; connects muscle to bone and resists tensile forces

Question 8

Which of the following best describes the role of mesenchyme in connective tissue development?

Accepted Answer

It is the embryonic tissue from which all connective tissues are derived.

Question 9

A patient suffers a deep cut that damages both the epidermis and the underlying connective tissue. Which two major tissue types are primarily involved in the healing process?

Accepted Answer

Epithelial and connective tissue

Question 10

Which of the following muscle tissue types is under voluntary control and is characterized by striations?

Accepted Answer

Skeletal muscle

Question 11

A histology slide shows branching cells with intercalated discs and striations. Which tissue type is being observed, and where is it found?

Accepted Answer

Cardiac muscle; heart wall

Question 12

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

Accepted Answer

Initiation and transmission of electrical impulses for communication and control

Question 13

A patient has a disease that destroys the myelin sheath of neurons. Which function is most likely to be impaired?

Accepted Answer

Rapid transmission of electrical impulses along axons

Question 14

Which of the following equations correctly represents the relationship between force ($$F$$), cross-sectional area ($$A$$), and stress ($$\sigma) in $$connective tissue?

Accepted Answer

$$F = \sigma 	imes A$$

Question 15

A gland is classified as a compound tubuloalveolar exocrine gland. Which of the following best describes its structure?

Accepted Answer

It has branched ducts with both tubular and alveolar (sac-like) secretory portions.

Question 16

Which of the following scenarios best illustrates the function of transitional epithelium?

Accepted Answer

Lining the urinary bladder, allowing it to stretch and recoil as it fills and empties

Question 17

A researcher is studying the difference between endocrine and exocrine glands. Which of the following statements is correct?

Accepted Answer

Endocrine glands lack ducts and secrete hormones into the blood, while exocrine glands use ducts to secrete onto surfaces.

Question 18

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

Accepted Answer

Cartilage is avascular, so nutrients and cells required for repair must diffuse from surrounding tissues.

Question 19

A patient is diagnosed with Marfan syndrome, a genetic disorder affecting connective tissue. Which of the following symptoms is most likely related to the function of connective tissue?

Accepted Answer

Abnormal flexibility and weakness in ligaments and blood vessel walls

Question 20

Which of the following best describes the main difference between simple and stratified epithelial tissues?

Accepted Answer

Simple epithelium consists of a single layer of cells, while stratified epithelium consists of multiple layers of cells.
