Question 2

A biopsy reveals epithelial cells with cube-like shapes and large, central nuclei lining the kidney tubules. Which type of epithelium is this, and what is its main function?

Accepted Answer

Simple cuboidal epithelium; secretion and absorption

Question 3

Which microscopy technique would be most appropriate for visualizing the detailed structure of the basement membrane in epithelial tissue?

Accepted Answer

Transmission electron microscopy

Question 4

Which of the following correctly matches the cell shape and function of columnar epithelial cells in the small intestine?

Accepted Answer

Tall, rectangular cells; absorption and secretion

Question 5

A patient with a genetic defect in desmosomes is likely to experience which of the following symptoms?

Accepted Answer

Fragile skin prone to blistering due to weak cell-cell adhesion

Question 6

Which connective tissue type is primarily responsible for storing energy and providing insulation?

Accepted Answer

Adipose tissue

Question 7

Which of the following best describes the structure and function of reticular tissue?

Accepted Answer

Loose network of reticular fibers; supports lymphoid organs

Question 8

A histological slide shows a tissue with chondrocytes embedded in a firm, gel-like matrix. Which tissue is this, and what is its primary function?

Accepted Answer

Cartilage; flexible support and shock absorption

Question 9

Which equation best represents the relationship between tissue regeneration rate ($$R$$), inflammation ($$I$$), and available stem cells ($$S) in $$response to injury?

Accepted Answer

$$R = \frac{S}{I}$$

Question 10

Which connective tissue type contains the greatest proportion of ground substance and is found beneath most epithelial layers?

Accepted Answer

Areolar tissue

Question 11

Which of the following is a function of neural tissue?

Accepted Answer

Transmission of electrical impulses

Question 12

Which type of membrane lines body cavities that do NOT open to the exterior and consists of simple squamous epithelium over areolar tissue?

Accepted Answer

Serous membrane

Question 13

A patient presents with chronic inflammation and poor tissue regeneration after injury. Which of the following is most likely impaired?

Accepted Answer

Availability of stem cells

Question 14

Which of the following best describes the arrangement of epithelial and connective tissues in the skin?

Accepted Answer

Stratified squamous epithelium over dense irregular connective tissue

Question 15

Which formula correctly expresses the tensile strength ($$T) of $$dense regular connective tissue as a function of collagen fiber density ($$C) $$and fiber alignment ($$A$$)?

Accepted Answer

$$T = C 	imes A$$

Question 16

Which tissue type is most likely to be damaged in a patient with osteogenesis imperfecta, and what is its primary function?

Accepted Answer

Bone; structural support and protection

Question 17

Which of the following best explains why transitional epithelium is found in the urinary bladder?

Accepted Answer

It permits stretching and recoiling as the bladder fills and empties

Question 18

Which of the following is a key function of muscle tissue in response to injury?

Accepted Answer

Contracting to limit blood loss

Question 19

Which equation best represents the relationship between the rate of inflammation ($$I$$), tissue damage ($$D$$), and immune cell concentration ($$M$$)?

Accepted Answer

$$I = D 	imes M$$

Question 20

Which of the following best describes the role of intercellular connections such as tight junctions in epithelial tissue?

Accepted Answer

They prevent leakage of substances between cells, maintaining tissue integrity
