Question 1

Which of the following is a primary function of epithelial tissue in the human body?

Accepted Answer

Covering body surfaces and lining body cavities for protection and absorption

Question 2

A patient presents with severe dehydration due to extensive burns. Which property of keratinized stratified squamous epithelium is most compromised in this scenario?

Accepted Answer

Its waterproof barrier function

Question 3

Which type of epithelial tissue is best suited for rapid exchange of gases in the alveoli of the lungs, and why?

Accepted Answer

Simple squamous epithelium, because its thin, single layer allows efficient diffusion

Question 4

Which of the following cell junctions is primarily responsible for preventing leakage of extracellular fluid between epithelial cells?

Accepted Answer

Tight junctions

Question 5

A biopsy of the urinary bladder reveals an epithelium with dome-shaped superficial cells when relaxed and squamous cells when distended. What type of epithelium is this?

Accepted Answer

Transitional epithelium

Question 6

Which connective tissue type is most abundant and serves as a model for support, binding, and holding body fluids?

Accepted Answer

Areolar connective tissue

Question 7

A patient with chronic knee pain and exposed bone on imaging is most likely suffering from damage to which tissue, and what is the clinical implication?

Accepted Answer

Cartilage; loss of cushioning and increased friction in the joint

Question 8

Which of the following best describes the extracellular matrix of connective tissue?

Accepted Answer

It is abundant and composed of ground substance and fibers

Question 9

Which formula correctly represents the relationship between edema and capillary permeability during inflammation?

Accepted Answer

$$Edema \propto Capillary\ Permeability$$

Question 10

Which of the following is a unique feature of nervous tissue compared to other tissue types?

Accepted Answer

Generates and conducts electrical impulses

Question 11

Which type of gland releases its products directly into the surrounding tissue fluid and produces hormones?

Accepted Answer

Endocrine gland

Question 12

Which surface feature of epithelial cells maximizes the surface area for absorption in the small intestine?

Accepted Answer

Microvilli

Question 13

A patient with a second-degree burn has lost the protective function of the epidermis. Which type of epithelium is primarily affected?

Accepted Answer

Keratinized stratified squamous epithelium

Question 14

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

Accepted Answer

Cartilage contains no blood vessels to deliver nutrients for repair

Question 15

Which equation best represents the relationship between the number of cell layers ($$n) in $$stratified epithelia and its protective function ($$P$$)?

Accepted Answer

$$P \propto n$$

Question 16

Which connective tissue type is specialized for storing nutrients as fat and aiding in thermoregulation, especially in infants?

Accepted Answer

Brown adipose tissue

Question 17

Which of the following is a function of the basal lamina in epithelial tissue?

Accepted Answer

Acts as a selective filter for molecules entering the epithelium

Question 18

Which type of cell junction allows ions and small molecules to pass directly from one cell to another, facilitating communication?

Accepted Answer

Gap junctions

Question 19

Which tissue type is responsible for movement and contains myofilaments composed of actin and myosin?

Accepted Answer

Muscle tissue

Question 20

During tissue repair, which process involves the replacement of destroyed tissue with the same type of tissue?

Accepted Answer

Regeneration
