Question 1

Which of the following best describes the main difference between simple squamous epithelium and stratified squamous epithelium?

Accepted Answer

Simple squamous epithelium is a single layer of flat cells allowing rapid diffusion, while stratified squamous epithelium has multiple layers providing protection against abrasion.

Question 2

Which connective tissue cell type is primarily responsible for producing collagen fibers and aiding in wound healing?

Accepted Answer

Fibroblast

Question 3

A patient presents with a third-degree burn. Which skin layers are affected, and what is a major health risk associated with this type of burn?

Accepted Answer

Epidermis and dermis are destroyed, and the major risk is dehydration and infection due to loss of barrier function.

Question 4

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

Accepted Answer

$$Bone\ Mass = Bone\ Formation - Bone\ Resorption$$

Question 5

Which type of cartilage is found in the intervertebral discs and is best suited to resist compression?

Accepted Answer

Fibrocartilage

Question 6

A patient with osteoporosis is at increased risk for fractures. Which of the following is NOT a common risk factor for osteoporosis?

Accepted Answer

High physical activity

Question 7

Which of the following best describes the function of pseudostratified ciliated columnar epithelium in the respiratory tract?

Accepted Answer

It secretes mucus and uses cilia to move particles out of the airways.

Question 8

During the process of bone repair, which of the following is the correct sequence of the four main steps?

Accepted Answer

Hematoma formation, fibrocartilaginous callus formation, bony callus formation, bone remodeling

Question 9

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

Accepted Answer

Ligaments have a poor blood supply compared to bone, limiting nutrient delivery and waste removal.

Question 10

Which layer of the epidermis is responsible for cell division and regeneration?

Accepted Answer

Stratum basale

Question 11

Which of the following is a function of macrophages in connective tissue?

Accepted Answer

Phagocytosing pathogens and cellular debris

Question 12

Which vitamin is essential for calcium absorption in the intestines and bone mineralization?

Accepted Answer

Vitamin D

Question 13

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

Accepted Answer

Exocrine glands secrete products onto epithelial surfaces via ducts, while endocrine glands release hormones directly into the bloodstream.

Question 14

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

Accepted Answer

Production of red blood cells

Question 15

Which of the following best describes the role of osteoclasts in bone remodeling?

Accepted Answer

Osteoclasts resorb bone tissue, breaking down the mineral matrix.

Question 16

A patient has a cutaneous melanoma. Which of the following factors is most important in determining the severity and prognosis?

Accepted Answer

The depth of invasion into the skin layers

Question 17

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

Accepted Answer

Interstitial growth increases bone length by expanding cartilage within the epiphyseal plate, while appositional growth increases bone diameter by adding new bone to the periosteum.

Question 18

Which of the following is a correct description of the function of chondrocytes in cartilage?

Accepted Answer

Chondrocytes produce and maintain the cartilaginous matrix, including collagen and proteoglycans.

Question 19

Which of the following best explains why edema occurs during inflammation?

Accepted Answer

Increased permeability of blood vessels allows plasma proteins and fluid to leak into the surrounding tissue.
