Accepted Answer

Rapid diffusion of gases

Question 2

A patient presents with a wound that heals by fibrosis rather than regeneration. Which of the following is a likely consequence?

Accepted Answer

Scar tissue forms, potentially impairing organ function

Question 3

Which of the following statements about epithelial tissue is TRUE?

Accepted Answer

Epithelial tissue is supported by connective tissue

Question 4

Which type of connective tissue is most likely to be found in tendons and ligaments, and why?

Accepted Answer

Dense regular connective tissue, because its parallel collagen fibers provide high tensile strength

Question 5

Which of the following best explains why cartilage injuries heal slowly in adults?

Accepted Answer

Cartilage is avascular and chondrocytes divide slowly

Question 6

A biopsy reveals a single layer of tall, closely packed cells with microvilli and goblet cells. Which tissue is this most likely to be?

Accepted Answer

Simple columnar epithelium

Question 7

Which of the following is a function of areolar connective tissue?

Accepted Answer

Universal packing material between other tissues

Question 8

Which mode of secretion involves the entire secretory cell rupturing to release its product?

Accepted Answer

Holocrine

Question 9

A tissue sample shows cells with striations, multiple nuclei, and voluntary control. Which tissue is this?

Accepted Answer

Skeletal muscle

Question 10

Which of the following best describes the basement membrane?

Accepted Answer

A structure composed of basal and reticular lamina that reinforces the epithelial sheet

Question 11

Which of the following equations best represents the process of diffusion across a simple squamous epithelium?

Accepted Answer

$$ J = -D \frac{\Delta C}{\Delta x} $$

Question 12

Which of the following cell types is responsible for producing the matrix in bone tissue?

Accepted Answer

Osteoblasts

Question 13

A patient with a genetic defect in collagen synthesis would most likely have problems with which tissue function?

Accepted Answer

High tensile strength in connective tissues

Question 14

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

Accepted Answer

Endocrine glands are ductless and secrete hormones into blood; exocrine glands secrete products onto surfaces or into cavities

Question 15

Which of the following tissues has the poorest regenerative capacity?

Accepted Answer

Cardiac muscle

Question 16

A patient with severe burns loses the protective function of which membrane?

Accepted Answer

Cutaneous membrane

Question 17

Which of the following best explains why the urinary bladder can stretch and return to its original shape?

Accepted Answer

It is lined with transitional epithelium

Question 18

Which of the following is a characteristic of nervous tissue?

Accepted Answer

Transmits electrical impulses

Question 19

Which of the following best describes the role of mast cells in connective tissue?

Accepted Answer

They initiate local inflammatory responses by releasing histamine and heparin

Question 20

Which embryonic germ layer gives rise to muscle and connective tissues?

Accepted Answer

Mesoderm
