Question 7

A biopsy of a patient's tissue reveals cells with large fat droplets and a function in energy storage and insulation. Which tissue type is this?

Accepted Answer

Adipose tissue

Question 8

Which of the following is TRUE regarding cartilage and its ability to heal after injury?

Accepted Answer

Cartilage is avascular and heals slowly due to limited nutrient supply

Question 9

Which tissue membrane lines the body cavities that open to the exterior and is lubricated by mucus to facilitate absorption and secretion?

Accepted Answer

Question 10

A patient with chronic joint pain is found to have reduced production of synovial fluid. Which tissue membrane is directly responsible for this function?

Accepted Answer

Synovial membrane

Question 11

Which muscle tissue type is characterized by striations, voluntary control, and multinucleate cells?

Accepted Answer

Skeletal muscle

Question 12

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

Accepted Answer

Cardiac muscle cells are replaced by fibrous tissue rather than regenerating

Question 13

Which of the following is a function of neuroglia in nervous tissue?

Accepted Answer

Providing nutrients and structural support to neurons

Question 14

During inflammation, which cell type releases histamine and heparin to stimulate the inflammatory response?

Accepted Answer

Mast cells

Question 15

Which of the following equations correctly represents the relationship between tissue volume ($$V$$), matrix volume ($$M$$), and cell volume ($$C) in $$connective tissue, if the matrix makes up most of the tissue volume?

Accepted Answer

$$V = M + C$$

Question 16

A patient presents with a condition where the skin is thin, fragile, and bruises easily. Which process is most likely impaired due to aging?

Accepted Answer

Regeneration and repair of tissue

Question 17

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

Accepted Answer

Endocrine glands release hormones directly into the bloodstream; exocrine glands release secretions onto epithelial surfaces through ducts

Question 18

Which type of cartilage is found in the intervertebral discs and is most resistant to compression and bone-to-bone contact?

Accepted Answer

Fibrocartilage

Question 19

Which of the following is a correct sequence of events during tissue response to injury?

Accepted Answer

Inflammation followed by regeneration

Question 20

A patient is diagnosed with cancer caused by environmental factors. If 70-80% of cancers are due to chemical exposure and 40% of those are caused by cigarette smoke, what is the probability ($$P) $$that a randomly selected cancer case is due to cigarette smoke? Use $$P = 0.4 	imes 0.75$$ for your calculation.

Accepted Answer
