Question 1

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

Accepted Answer

Endocrine glands secrete hormones directly into the bloodstream, while exocrine glands release their products onto epithelial surfaces via ducts.

Question 2

A patient presents with a burn affecting the entire right arm and the anterior trunk. Using the Rule of Nines, what percentage of the patient's body surface area is burned?

Accepted Answer

$ 9\% + 18\% = 27\% $

Question 3

Which connective tissue fiber type provides the greatest tensile strength to tissues such as tendons and ligaments?

Accepted Answer

Collagen fibers

Question 4

Which layer of the epidermis is primarily responsible for the generation of new skin cells and contains melanocytes?

Accepted Answer

Stratum basale

Question 5

A patient has a keloid formation after a skin injury. What is the underlying cause of a keloid?

Accepted Answer

Excessive collagen deposition during the healing process

Question 6

Which of the following is a unicellular exocrine gland found in epithelial tissue?

Accepted Answer

Goblet cell

Question 7

Which type of epithelial tissue is best suited for diffusion and is found lining the alveoli of the lungs?

Accepted Answer

Simple squamous epithelium

Question 8

Which connective tissue type contains all three fiber types (collagen, elastic, and reticular) and is found beneath epithelial membranes?

Accepted Answer

Areolar connective tissue

Question 9

Which sweat gland type is primarily responsible for thermoregulation and is widely distributed across the body?

Accepted Answer

Merocrine (eccrine) gland

Question 10

A patient is diagnosed with basal cell carcinoma. Where is this cancer most likely to originate?

Accepted Answer

Cells of the stratum basale in the epidermis

Question 11

Which of the following best describes the function of the arrector pili muscle?

Accepted Answer

Contracts to cause hair to stand upright, producing 'goosebumps'

Question 12

Which layer of the dermis contains papillary ridges and is responsible for fingerprints?

Accepted Answer

Papillary layer

Question 13

Which of the following is a function of the integumentary system?

Accepted Answer

Protection against mechanical injury and pathogens

Question 14

Which type of epithelial cell is specialized for secretion and is commonly found in glands?

Accepted Answer

Cuboidal cells

Question 15

A patient has a burn that affects the epidermis and the entire dermis but not underlying tissues. What type of burn is this?

Accepted Answer

Full-thickness (third-degree) burn

Question 16

Which connective tissue type is found in tendons and ligaments and is characterized by parallel bundles of collagen fibers?

Accepted Answer

Dense regular connective tissue

Question 17

Which of the following is a multicellular exocrine gland with a branched duct system?

Accepted Answer

Compound gland

Question 18

Which of the following is a major difference between apocrine and merocrine sweat glands?

Accepted Answer

Apocrine glands secrete into hair follicles and are activated at puberty, while merocrine glands secrete directly onto the skin surface and function in thermoregulation.

Question 19

Which connective tissue fiber type forms a supportive network in soft organs such as the spleen and lymph nodes?

Accepted Answer

Reticular fibers

Question 20

A patient in Washington state is diagnosed with melanoma. Compared to basal cell carcinoma, which statement is most accurate regarding melanoma?

Accepted Answer

Melanoma has a lower incidence but a higher mortality rate than basal cell carcinoma.
