Question 1

Which of the following best describes the main functional difference between epithelial and connective tissues?

Accepted Answer

Epithelial tissue forms protective barriers and is involved in absorption and secretion, while connective tissue supports, binds, and protects other tissues.

Question 2

A patient suffers a deep cut that damages both the epidermis and the dermis. Which process is most likely to occur during healing?

Accepted Answer

Both inflammation and organization will occur, followed by regeneration and possible fibrosis (scar formation).

Question 3

Which of the following is a characteristic unique to nervous tissue compared to the other primary tissue classes?

Accepted Answer

Has the ability to generate and conduct electrical impulses.

Question 4

Which of the following scenarios is most likely to result in chronic inflammation?

Accepted Answer

A persistent bacterial infection that is not cleared by the immune system.

Question 5

Which tissue type has the greatest regenerative capacity after injury?

Accepted Answer

Epithelial tissue

Question 6

A second-degree burn affects which layers of the skin, and what is a common complication?

Accepted Answer

Epidermis and upper dermis; blister formation.

Question 7

Which of the following best explains why elderly individuals are more prone to heat stroke?

Accepted Answer

Aging skin has reduced sweat gland activity and decreased blood flow, impairing thermoregulation.

Question 8

A patient presents with yellowish skin and sclera. Which underlying condition is most likely indicated by this skin color change?

Accepted Answer

Jaundice due to liver dysfunction

Question 9

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

Accepted Answer

Production of hormones

Question 10

Which bone cell type is primarily responsible for bone resorption, and what is the main chemical process involved?

Accepted Answer

Osteoclast; secretion of acids and enzymes to dissolve bone matrix

Question 11

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; spongy bone is porous and found at the ends of long bones.

Question 12

Hematopoiesis is the process of blood cell formation. Where does this process primarily occur in adults?

Accepted Answer

Red bone marrow in spongy bone of flat bones

Question 13

Which hormone increases blood calcium levels by stimulating osteoclast activity?

Accepted Answer

Parathyroid hormone (PTH)

Question 14

A patient with osteoporosis is at increased risk for fractures due to which underlying mechanism?

Accepted Answer

Increased bone resorption by osteoclasts leading to decreased bone mass

Question 15

Which of the following best describes the process of endochondral ossification?

Accepted Answer

Bone replaces a hyaline cartilage model during fetal development.

Question 16

A 30-year-old male fractures his femur. Which of the following correctly lists the sequence of events in bone repair?

Accepted Answer

Hematoma formation → fibrocartilaginous callus formation → bony callus formation → bone remodeling

Question 17

Which nutritional deficiency is most likely to impair bone maintenance and increase the risk of rickets in children?

Accepted Answer

Vitamin D deficiency

Question 18

A patient presents with a blister after wearing new shoes. Which best explains the formation of the blister?

Accepted Answer

Accepted Answer

$$9\%$$

Question 20

Which of the following is a function of sebaceous glands in the skin?

Accepted Answer
