Question 1

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

Accepted Answer

They break down and resorb bone tissue during bone remodeling.

Question 2

A patient presents with a suspicious mole on their skin. Which layer of the epidermis is most likely to be involved in the development of melanoma?

Accepted Answer

Stratum basale

Question 3

Which of the following is a correct match between a type of epithelial tissue and its primary function?

Accepted Answer

Stratified squamous epithelium – protection against abrasion

Question 4

Which of the following glands is classified as an exocrine gland and what is its primary mode of secretion?

Accepted Answer

Sebaceous gland; secretes sebum through ducts to the skin surface

Question 5

A child is diagnosed with a growth hormone deficiency. Which structure in the bone is most directly affected, and what is the likely result?

Accepted Answer

Epiphyseal plate; reduced longitudinal bone growth

Question 6

Which of the following best explains why the epidermis is avascular?

Accepted Answer

It allows for rapid diffusion of nutrients from the dermis.

Question 7

A biopsy reveals hyaline cartilage in a patient's trachea. Which cell type is primarily responsible for producing the extracellular matrix in this tissue?

Accepted Answer

Chondroblasts

Question 8

Which of the following scenarios best illustrates the function of the stratum corneum in the epidermis?

Accepted Answer

A person’s skin forms a callus after repeated friction.

Question 9

Which hormone is primarily responsible for stimulating bone growth at the epiphyseal plate during childhood?

Accepted Answer

Growth hormone

Question 10

A patient with a pituitary tumor has excessive growth hormone secretion after the epiphyseal plates have closed. What condition is most likely to develop?

Accepted Answer

Acromegaly

Question 11

Which of the following best describes the difference between merocrine and holocrine glands?

Accepted Answer

Merocrine glands release their products by exocytosis, while holocrine glands release their products by rupturing the entire cell.

Question 12

A patient has a mutation that prevents the formation of keratin in the epidermis. Which of the following consequences is most likely?

Accepted Answer

Increased susceptibility to mechanical injury

Question 13

Which of the following equations correctly represents the process of bone resorption by osteoclasts?

Accepted Answer

$$\mathrm{Ca}_{10}(\mathrm{PO}_4)_6(\mathrm{OH})_2 \rightarrow 10\ \mathrm{Ca}^{2+} + 6\ \mathrm{PO}_4$$^{3-}$$ + 2\ \mathrm{OH}^-$$

Question 14

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

Accepted Answer

Cartilage is avascular, so nutrients and cells required for repair must diffuse from surrounding tissues.

Question 15

A patient with a burn that destroys the entire epidermis and part of the dermis will have difficulty with which of the following functions?

Accepted Answer

Regulation of body temperature and prevention of water loss

Question 16

Which of the following is a correct statement about the organization of bone tissue?

Accepted Answer

Compact bone is organized into osteons, while spongy bone contains trabeculae.

Question 17

A 12-year-old child fractures their femur at the epiphyseal plate. What is the most likely long-term consequence if the injury is not properly treated?

Accepted Answer

The bone may stop growing in length, leading to limb length discrepancy.

Question 18

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

Accepted Answer

They synthesize melanin to protect against UV radiation.

Question 19

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

Accepted Answer

Endocrine glands secrete hormones directly into the bloodstream, while exocrine glands secrete their products through ducts to an epithelial surface.

Question 20

A patient is diagnosed with basal cell carcinoma. Which of the following statements best describes this type of cancer?

Accepted Answer

It originates in the stratum basale and is the most common type of skin cancer.
