Question 2

A patient presents with a skin lesion that is unusually pale compared to surrounding tissue. Which pigment is most likely decreased, and what pathology might this indicate?

Accepted Answer

Decreased melanin; possible vitiligo.

Question 3

Which equation correctly represents the relationship between bone density ($D$), mass ($m$), and volume ($V$)?

Accepted Answer

$D = \frac{m}{V}$

Question 4

Which type of epithelial tissue is best suited for rapid diffusion and where is it commonly found?

Accepted Answer

Simple squamous; alveoli of the lungs.

Question 5

A long bone is fractured and the marrow is exposed. Which type of marrow is most likely to be found in the diaphysis of an adult femur, and what is its primary function?

Accepted Answer

Yellow marrow; fat storage.

Question 6

Which of the following best explains why compact bone is stronger than spongy bone?

Accepted Answer

Compact bone has a dense arrangement of osteons.

Question 7

A patient with a burn affecting only the epidermis is classified as having which type of burn, and what is the expected healing outcome?

Accepted Answer

First-degree burn; heals without scarring.

Question 8

Which connective tissue fiber type provides the greatest tensile strength, and what is its primary protein component?

Accepted Answer

Collagen fibers; collagen.

Question 9

Which of the following best describes the function of synovial fluid in a joint?

Accepted Answer

It lubricates the joint and nourishes articular cartilage.

Question 10

A patient is diagnosed with osteoporosis. Which change in the bone matrix is most likely responsible for this condition?

Accepted Answer

Decreased inorganic component, leading to reduced bone strength.

Question 11

Which of the following is a distinguishing feature of nervous tissue compared to other major tissue types?

Accepted Answer

Specialized for rapid communication via electrical impulses.

Question 12

Which equation correctly represents the calculation of surface area ($A$) of a rectangular skin patch with length ($l$) and width ($w$)?

Accepted Answer

$A = l 	imes w$

Question 13

Which of the following best describes the difference between fibrous and cartilaginous joints?

Accepted Answer

Fibrous joints are connected by dense connective tissue, while cartilaginous joints are connected by cartilage.

Question 14

A patient has a mutation affecting keratinocyte function. Which layer of the skin is most likely to be impacted?

Accepted Answer

Epidermis.

Question 15

Which of the following best explains why the skull of a newborn differs from that of an adult?

Accepted Answer

The newborn skull has more fibrous joints called fontanelles.

Question 16

Which of the following is a function of the skin’s accessory structures?

Accepted Answer

Regulation of body temperature through sweat glands.

Question 17

Which tissue type is most likely to be found lining the urinary bladder, and what is its key property?

Accepted Answer

Transitional epithelium; stretchability.

Question 18

A patient suffers a ligament injury in the knee. Which type of connective tissue is primarily affected, and what is its main function?

Accepted Answer

Dense regular connective tissue; connecting bone to bone.

Question 19

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

Accepted Answer

They maintain bone matrix and communicate with other bone cells.

Question 20

Which equation correctly represents the calculation of the volume ($V$) of a cylindrical long bone with radius ($r$) and height ($h$)?

Accepted Answer

$V = \pi r^2 h$
