Question 1

Which of the following best describes the main functional characteristic of epithelial tissue?

Accepted Answer

It covers body surfaces and lines cavities, providing protection, absorption, and secretion.

Question 2

A patient presents with a burn that has destroyed both the epidermis and the entire dermis. Which type of skin repair process will primarily occur?

Accepted Answer

Fibrosis, resulting in scar tissue formation.

Question 3

Which of the following best distinguishes between exocrine and endocrine glands?

Accepted Answer

Exocrine glands secrete their products onto body surfaces or into body cavities via ducts, while endocrine glands release hormones directly into the bloodstream.

Question 4

Which of the following is a correct pairing of connective tissue type and its function?

Accepted Answer

Hyaline cartilage – provides flexible support and reduces friction at joints.

Question 5

A 65-year-old patient is experiencing thinning skin, increased bruising, and slower wound healing. Which physiological changes of aging best explain these symptoms?

Accepted Answer

Decreased collagen and elastin fibers, reduced vascularity, and slower cell turnover.

Question 6

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

Accepted Answer

Cartilage is replaced by bone tissue, forming most of the long bones.

Question 7

A child has a fracture at the epiphyseal plate of the femur. What is the most likely consequence if the injury is not properly treated?

Accepted Answer

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

Question 8

Which hormone increases blood calcium levels by stimulating osteoclast activity?

Accepted Answer

Parathyroid hormone (PTH)

Question 9

A patient is diagnosed with osteoporosis. Which of the following best explains the pathophysiology of this disease?

Accepted Answer

Increased bone resorption relative to bone deposition, leading to decreased bone mass.

Question 10

Which of the following is a characteristic of synovial joints?

Accepted Answer

They are freely movable and contain a fluid-filled joint cavity.

Question 11

A patient with rheumatoid arthritis is experiencing joint pain and swelling. Which of the following best describes the underlying cause?

Accepted Answer

Autoimmune inflammation of the synovial membrane.

Question 12

Which of the following equations correctly represents the relationship between bone mass, bone deposition, and bone resorption?

Accepted Answer

$	ext{Bone Mass} = 	ext{Bone Deposition} - 	ext{Bone Resorption}$

Question 13

Which of the following best explains why elderly individuals are more prone to bone fractures?

Accepted Answer

Decreased bone density due to increased bone resorption and decreased bone formation.

Question 14

A patient is diagnosed with osteoarthritis. Which of the following is the primary pathological change in this condition?

Accepted Answer

Loss of articular cartilage and formation of bone spurs.

Question 15

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

Accepted Answer

They produce melanin, which protects against UV radiation.

Question 16

Which of the following is a correct sequence of events in bone fracture repair?

Accepted Answer

Hematoma formation → Fibrocartilaginous callus formation → Bony callus formation → Bone remodeling

Question 17

A patient with Lyme disease presents with joint pain and swelling. What is the most likely cause of these symptoms?

Accepted Answer

Bacterial infection transmitted by a tick bite leading to inflammation of the joints.

Question 18

Which of the following best describes the role of osteoblasts in bone tissue?

Accepted Answer

They produce new bone matrix, contributing to bone growth and repair.

Question 19

Which of the following is a function of the hypodermis (subcutaneous layer) of the skin?

Accepted Answer

Stores fat and anchors the skin to underlying structures.

Question 20

A patient is unable to sweat due to a genetic disorder affecting their sweat glands. Which of the following is a likely consequence?

Accepted Answer

Increased risk of dehydration and overheating due to impaired thermoregulation.
