Question 1

Which of the following best describes the primary function of tight junctions in epithelial tissue?

Accepted Answer

They prevent the passage of solutes between cells, maintaining selective permeability.

Question 2

A patient presents with a skin wound that heals with a raised, shiny scar. Which process is most responsible for this outcome?

Accepted Answer

Excessive fibrosis resulting in keloid formation

Question 3

Which type of connective tissue fiber is most abundant and provides resistance to force in one direction, such as in tendons?

Accepted Answer

Collagen fibers

Question 4

Which of the following equations best represents the relationship between tissue growth and cell number in hyperplasia?

Accepted Answer

$$N_{final} = N_{initial} + \Delta N_{cells}$$

Question 5

Which type of epithelial tissue is best suited for areas subject to abrasion, such as the skin and oral cavity?

Accepted Answer

Stratified squamous epithelium

Question 6

A gland that releases its product by shedding the apical portion of its cytoplasm is classified as which type of gland?

Accepted Answer

Apocrine gland

Question 7

Which of the following is NOT a characteristic of all epithelial tissues?

Accepted Answer

Vascularity

Question 8

Which connective tissue cell type is primarily responsible for producing the matrix (fibers and ground substance)?

Accepted Answer

Fibroblasts

Question 9

Which membrane lines body cavities that are not open to the outside and reduces friction between organs?

Accepted Answer

Serous membrane

Question 10

A patient with liver cirrhosis shows excessive scar tissue formation. Which process is most likely impaired?

Accepted Answer

Regeneration of hepatocytes

Question 11

Which type of muscle tissue is striated, involuntary, and contains intercalated discs for cell-to-cell communication?

Accepted Answer

Cardiac muscle

Question 12

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

Accepted Answer

Chondrocytes produce antiangiogenesis factor, making cartilage avascular.

Question 13

Which equation best represents the process of atrophy in tissue due to disuse?

Accepted Answer

$$S_{final} = S_{initial} - \Delta S_{cell}$$

Question 14

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

Accepted Answer

Serves as a passageway for nerves and blood vessels under epithelia

Question 15

Which type of cell junction is most important for coordinating contraction in cardiac muscle?

Accepted Answer

Gap junctions

Question 16

Which of the following best describes the difference between endocrine and exocrine glands?

Accepted Answer

Endocrine glands release products directly into interstitial fluid; exocrine glands release products onto epithelial surfaces via ducts.

Question 17

Which type of connective tissue is found in the walls of arteries and allows them to stretch and recoil?

Accepted Answer

Elastic connective tissue

Question 18

Which of the following is a real-life example of apoptosis in human development?

Accepted Answer

Webbing of fingers and toes in the fetus disappearing before birth

Question 19

Which membrane is thick, water-resistant, and forms the outer covering of the body?

Accepted Answer

Cutaneous membrane

Question 20

Which of the following best explains why aging leads to increased bruising and bone brittleness?

Accepted Answer

Thinning of epithelial and connective tissues, and reduced tissue repair efficiency
