Question 1

Which of the following best describes the main function of simple squamous epithelium in the human body?

Accepted Answer

Rapid diffusion and filtration across thin barriers

Question 2

A biopsy sample is stained and observed under a microscope. The tissue appears as a single layer of tall, rectangular cells with nuclei aligned near the base. Which tissue type is most likely being observed?

Accepted Answer

Simple columnar epithelium

Question 3

Which of the following statements about connective tissue is CORRECT?

Accepted Answer

Connective tissue consists of cells scattered in an abundant extracellular matrix.

Question 4

A patient suffers a tendon injury. Which type of connective tissue is primarily affected, and what is its main structural protein?

Accepted Answer

Dense regular connective tissue; collagen

Question 5

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

Accepted Answer

Cartilage is avascular, while bone is highly vascularized.

Question 6

Which secretion method involves the entire cell rupturing to release its product, and what is a classic example of this gland type?

Accepted Answer

Holocrine secretion; sebaceous (oil) glands

Question 7

A tissue sample from the urinary bladder shows cells that change shape from cuboidal to squamous as the bladder fills. What type of epithelium is this?

Accepted Answer

Transitional epithelium

Question 8

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

Accepted Answer

Endocrine glands are ductless and release hormones into the bloodstream; exocrine glands secrete products onto epithelial surfaces via ducts.

Question 9

Which of the following best describes the role of astrocytes in nervous tissue?

Accepted Answer

They maintain homeostasis of the central nervous system environment.

Question 10

A patient has a wound that heals with scar tissue rather than the original tissue type. Which process is primarily responsible for this outcome?

Accepted Answer

Fibrosis

Question 11

Which of the following best describes the sequence of events in tissue repair after injury?

Accepted Answer

Inflammation → Organization → Permanent repair

Question 12

Which membrane lines body cavities that open to the exterior and is adapted for absorption and secretion?

Accepted Answer

Mucous membrane

Question 13

Which of the following is a characteristic feature of pseudostratified columnar epithelium?

Accepted Answer

Cells appear layered due to nuclei at different heights, but all cells touch the basal lamina

Question 14

Which connective tissue type is specialized for fat storage and insulation?

Accepted Answer

Adipose tissue

Question 15

Which of the following best explains why bone is able to heal more rapidly than cartilage?

Accepted Answer

Bone is highly vascularized, providing nutrients and cells for repair.

Question 16

Which of the following is NOT a function of epithelial tissue?

Accepted Answer

Support

Question 17

Which cell type is responsible for producing the myelin sheath in the peripheral nervous system?

Accepted Answer

Schwann cells

Question 18

A gland that releases its product by exocytosis without losing any part of the cell is classified as which type of gland?

Accepted Answer

Merocrine

Question 19

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

Accepted Answer

It consists of ground substance and protein fibers such as collagen, elastic, and reticular fibers.

Question 20

Which of the following is a real-life example of a tissue that is highly regenerative due to its exposure to frequent abrasion?

Accepted Answer

Stratified squamous epithelium of the skin
