Q: Which equation best represents the relationship between tissue repair and blood supply?

$$\text{Tissue Repair Rate} \propto \text{Blood Supply}$$

Q: A patient with a vitamin C deficiency is likely to have impaired tissue repair. Which equation best explains the relationship between vitamin C and collagen synthesis?

$$\text{Collagen Synthesis Rate} \propto \text{Vitamin C Concentration}$$

Question 1

Which of the following best describes the extracellular matrix (ECM) in connective tissues?

Accepted Answer

It is composed of ground substance and protein fibers, providing structural and biochemical support to surrounding cells.

Question 2

A patient presents with a burn that has destroyed the epidermis and part of the dermis. Which tissue repair process is most likely to occur, and why?

Accepted Answer

Fibrosis, because the damage extends into connective tissue and the cells cannot fully regenerate.

Question 3

Which equation best represents the relationship between tissue repair and blood supply?

Accepted Answer

$$	ext{Tissue Repair Rate} \propto 	ext{Blood Supply}$$

Question 4

Which of the following cell junctions is most important for preventing substances from passing between cells in the lining of the stomach?

Accepted Answer

Tight junctions

Question 5

Which statement best describes the difference between endocrine and exocrine glands?

Accepted Answer

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

Question 6

Which of the following is the most common unicellular exocrine gland, and what is its primary function?

Accepted Answer

Goblet cell; secretes mucus to protect and lubricate epithelial surfaces.

Question 7

A multicellular exocrine gland with a branched duct and sac-like secretory portions is best described as:

Accepted Answer

Compound acinar (alveolar)

Question 8

Which secretion mechanism involves the entire cell rupturing to release its contents?

Accepted Answer

Holocrine secretion

Question 9

Which connective tissue cell is primarily responsible for producing collagen fibers?

Accepted Answer

Fibroblast

Question 10

Which specialized connective tissue is characterized by a rigid matrix containing calcium phosphate and collagen fibers?

Accepted Answer

Bone

Question 11

A patient with a vitamin C deficiency is likely to have impaired tissue repair. Which equation best explains the relationship between vitamin C and collagen synthesis?

Accepted Answer

$$	ext{Collagen Synthesis Rate} \propto 	ext{Vitamin C Concentration}$$

Question 12

Which membrane lines body cavities that do NOT open to the exterior and produces a watery fluid?

Accepted Answer

Serous membrane

Question 13

Which tissue type is specialized for rapid communication and control of body functions?

Accepted Answer

Nervous tissue

Question 14

Which of the following best describes the function of muscle tissue?

Accepted Answer

Contraction to produce movement

Question 15

Which of the following is NOT a true membrane?

Accepted Answer

Synovial membrane

Question 16

Which scenario best illustrates the application of tight junctions in a real-world context?

Accepted Answer

Preventing leakage of stomach acid into underlying tissues.

Question 17

Which tissue is most likely to repair by regeneration rather than fibrosis?

Accepted Answer

Epithelial tissue

Question 18

Which of the following best describes the function of the ground substance in the extracellular matrix?

Accepted Answer

It fills the space between cells and fibers, providing support and facilitating exchange of nutrients and waste.

Question 19

Which membrane-like structure is found lining joint cavities and produces a lubricating fluid?

Accepted Answer

Synovial membrane

Question 20

A patient with poor nutrition and low blood supply to a wound is most likely to experience which outcome?

Accepted Answer

Delayed healing and increased fibrosis
