Question 1

Which of the following best describes the primary function of epithelial tissue?

Accepted Answer

Covering surfaces and lining cavities to protect and regulate exchange

Question 2

A patient presents with a burn that affects the epidermis and part of the dermis, causing blistering and pain. How would you classify this burn?

Accepted Answer

Second-degree burn

Question 3

Which connective tissue type is characterized by a matrix rich in collagen fibers and is found in tendons and ligaments?

Accepted Answer

Dense regular connective tissue

Question 4

Which cell type is primarily responsible for producing the extracellular matrix in connective tissue?

Accepted Answer

Fibroblast

Question 5

A patient has a genetic disorder affecting the elastic fibers in their skin and blood vessels. Which protein is most likely defective?

Accepted Answer

Elastin

Question 6

Which of the following best explains the difference between merocrine and apocrine sweat glands?

Accepted Answer

Merocrine glands secrete by exocytosis, while apocrine glands release part of the cell cytoplasm with their secretion.

Question 7

Which layer of the epidermis is responsible for the production of keratin?

Accepted Answer

Stratum spinosum

Question 8

A patient with a third-degree burn will experience which of the following symptoms?

Accepted Answer

Destruction of both epidermis and dermis, often with numbness due to nerve damage

Question 9

Which of the following is NOT a function of the integumentary system?

Accepted Answer

Production of red blood cells

Question 10

Which type of cartilage is found in the intervertebral discs and is characterized by its ability to resist compression?

Accepted Answer

Fibrocartilage

Question 11

A patient is diagnosed with melanoma. Which layer of the skin does this cancer originate from?

Accepted Answer

Epidermis

Question 12

Which of the following best describes the function of desmosomes in epithelial tissue?

Accepted Answer

Anchor cells together to resist mechanical stress

Question 13

Which of the following equations correctly represents the relationship between surface area ($A$) and volume ($V$) for a cube-shaped cell, and why is this important for tissue function?

Accepted Answer

$A = 6s^2$, $V = s^3$; a higher surface area to volume ratio allows for more efficient exchange of materials.

Question 14

Which of the following best describes the process of aging in the integumentary system?

Accepted Answer

Decreased melanocyte activity, reduced collagen, and slower wound healing

Question 15

A patient presents with hair loss (alopecia). Which of the following is a possible cause related to the integumentary system?

Accepted Answer

Autoimmune destruction of hair follicles

Question 16

Which of the following statements about the basement membrane is correct?

Accepted Answer

It separates epithelial tissue from underlying connective tissue and provides structural support.

Question 17

Which gland type is responsible for producing earwax (cerumen)?

Accepted Answer

Ceruminous gland

Question 18

A patient with a genetic mutation affecting collagen synthesis would most likely have problems with which tissue type?

Accepted Answer

Connective tissue

Question 19

Which of the following is a correct comparison between hyaline cartilage and elastic cartilage?

Accepted Answer

Elastic cartilage contains more elastic fibers, making it more flexible than hyaline cartilage.

Question 20

Which of the following best describes the role of melanocytes in the skin?

Accepted Answer

Producing melanin to protect against UV radiation
