Accepted Answer

Rapid diffusion of gases due to thin cell layers

Question 2

A patient suffers a sunburn, and the damaged skin peels off in sheets rather than as individual cells. Which type of cell junction is most responsible for this phenomenon?

Accepted Answer

Desmosomes

Question 3

Which connective tissue cell type is primarily responsible for producing collagen fibers and ground substance?

Accepted Answer

Fibroblasts

Question 4

Which type of membrane lines body cavities that open to the exterior, such as the digestive and respiratory tracts?

Accepted Answer

Mucous membrane

Question 5

A lack of vitamin C impairs the ability of fibroblasts to produce collagen. What is the most likely consequence for connective tissue?

Accepted Answer

Reduced strength and increased fragility

Question 6

Which type of muscle tissue is striated, multinucleated, and under voluntary control?

Accepted Answer

Skeletal muscle

Question 7

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

Accepted Answer

Cartilage is avascular, limiting nutrient delivery

Question 8

Which type of exocrine gland secretion involves the entire cell bursting to release its contents?

Accepted Answer

Holocrine secretion

Question 9

A tissue sample shows cells with many branching projections, including some several centimeters long. Which type of cell is most likely present?

Accepted Answer

Neuron

Question 10

Which of the following is a function of serous fluid produced by serous membranes?

Accepted Answer

Lubrication to reduce friction between organs

Question 11

Which connective tissue type is most likely to be found padding the kidneys and storing energy reserves?

Accepted Answer

Adipose connective tissue

Question 12

Which of the following best describes the difference between a plasma (cell) membrane and a tissue membrane?

Accepted Answer

Plasma membrane is a physical barrier made of proteins and lipids, while tissue membrane is a multicellular barrier composed of epithelial and connective tissues

Question 13

Which type of connective tissue fiber is most abundant and provides tensile strength to tissues such as tendons and ligaments?

Accepted Answer

Collagen fibers

Question 14

A patient presents with swelling, redness, heat, and pain after an injury. Which process is responsible for these symptoms?

Accepted Answer

Inflammation

Question 15

Which type of tissue membrane is found lining freely movable joints and produces a viscous fluid for lubrication?

Accepted Answer

Synovial membrane

Question 16

Which of the following is a major age-related change in tissue structure that increases the risk of osteoporosis in women?

Accepted Answer

Reduction in bone strength due to thinning and brittleness

Question 17

Which of the following best explains why cardiac muscle tissue has limited ability to repair after injury?

Accepted Answer

Most damaged cardiac muscle cells are replaced by fibrous connective tissue rather than new muscle cells

Question 18

Which type of epithelial tissue is best suited for areas exposed to severe mechanical stress, such as the skin and lining of the mouth?

Accepted Answer

Stratified squamous epithelium

Question 19

Which of the following equations best represents the relationship between tissue repair rate ($R$) and age ($A$), given that repair rate decreases with age?

Accepted Answer

$R = k - mA$,	ext{ where }k,m>0$

Question 20

Which of the following is a real-world example of a tissue membrane acting as a physical barrier to infection?

Accepted Answer

The cutaneous membrane (skin) preventing entry of pathogens into the body
