Question 1

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

Accepted Answer

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

Question 2

A patient presents with a burn that has destroyed both the epidermis and the entire dermis. Which of the following best describes the type of burn and its likely consequences?

Accepted Answer

Third-degree burn; loss of sensation due to destruction of nerve endings and high risk of fluid loss.

Question 3

Which of the following equations correctly represents the calculation of the total surface area affected by burns using the Rule of Nines for an adult?

Accepted Answer

$$Total\ Surface\ Area = (Head\ and\ Neck) + (Each\ Arm) + (Each\ Leg) + (Anterior\ Trunk) + (Posterior\ Trunk) + (Perineum)$$

Question 4

Which connective tissue type is characterized by a solid, mineralized extracellular matrix and is responsible for supporting and protecting organs?

Accepted Answer

Bone tissue

Question 5

A biopsy reveals a tissue with multiple layers of flat cells. Which type of epithelial tissue is this, and where is it most likely found?

Accepted Answer

Stratified squamous epithelium; found in the epidermis of the skin

Question 6

Which of the following best explains the process of intramembranous ossification?

Accepted Answer

Bone develops directly from mesenchymal tissue without a cartilage precursor.

Question 7

A 10-year-old child is experiencing rapid growth in height. Which region of the long bone is primarily responsible for this growth, and what is the process called?

Accepted Answer

Epiphyseal plate; interstitial growth

Question 8

Which of the following is a function of the integumentary system that directly contributes to homeostasis?

Accepted Answer

Regulation of body temperature through sweat production

Question 9

A patient with a genetic defect in collagen synthesis is most likely to have problems with which tissue type?

Accepted Answer

Connective tissue

Question 10

Which of the following best describes the difference between compact and spongy bone?

Accepted Answer

Compact bone is dense and forms the outer layer of bones, while spongy bone is porous and found mainly at the ends of long bones.

Question 11

Which of the following equations correctly represents the calculation of bone mass density (BMD)?

Accepted Answer

$$BMD = \frac{Bone\ Mass}{Bone\ Volume}$$

Question 12

Which of the following is NOT a function of the skin?

Accepted Answer

Production of insulin

Question 13

A patient has a tumor in the pituitary gland that is causing excessive hormone release. Which type of gland is the pituitary, and what is the likely route of hormone delivery?

Accepted Answer

Endocrine gland; hormones are released directly into the bloodstream

Question 14

Which of the following best describes the function of osteoclasts in bone tissue?

Accepted Answer

They break down bone matrix, releasing calcium into the blood.

Question 15

A patient with a blocked sweat gland is likely to experience which of the following symptoms?

Accepted Answer

Impaired thermoregulation and possible overheating

Question 16

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

Accepted Answer

Cartilage is avascular, so it lacks a direct blood supply for nutrient delivery and waste removal.

Question 17

Which of the following is a correct sequence of layers in the epidermis from deepest to most superficial?

Accepted Answer

Stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, stratum corneum

Question 18

A patient with osteoporosis is at increased risk for fractures. Which of the following best explains the underlying cause?

Accepted Answer

Decreased bone mass and density due to increased bone resorption by osteoclasts

Question 19

Which of the following best describes the function of the periosteum in bone?

Accepted Answer

It serves as a site for attachment of tendons and ligaments and contains cells for bone growth and repair.

Question 20

Which of the following best explains the difference between interstitial and appositional bone growth?

Accepted Answer

Interstitial growth increases bone length, while appositional growth increases bone width.
