Accepted Answer

Rapid diffusion of gases

Question 2

A patient presents with 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 of the following equations correctly represents the relationship between tissue repair rate ($R$), metabolic rate ($M$), and age ($A$), assuming repair rate decreases linearly with age?

Accepted Answer

$R = M - kA$

Question 5

Which type of membrane lines body cavities that are open to the exterior and is supported by areolar connective tissue called the lamina propria?

Accepted Answer

Mucous membrane

Question 6

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

Accepted Answer

Decreased strength and increased fragility

Question 7

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

Accepted Answer

Holocrine secretion

Question 8

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

Accepted Answer

Collagen fibers

Question 9

A tissue sample shows cells with multiple nuclei, striations, and no ability to divide. Which type of muscle tissue is this?

Accepted Answer

Skeletal muscle

Question 10

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

Accepted Answer

Cartilage is avascular and relies on diffusion for nutrient delivery

Question 11

Which tissue membrane is composed of stratified squamous epithelium, areolar tissue, and underlying dense irregular connective tissue, and is relatively waterproof?

Accepted Answer

Cutaneous membrane

Question 12

Which of the following cell types is most likely to release histamine and heparin during the inflammatory response?

Accepted Answer

Mast cells

Question 13

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

Accepted Answer

Lubrication to reduce friction between organs

Question 14

Which type of connective tissue proper is found in the dermis and is characterized by collagen fibers arranged in an irregular pattern?

Accepted Answer

Dense irregular connective tissue

Question 15

Which of the following best describes the main structural difference between pseudostratified columnar epithelium and stratified columnar epithelium?

Accepted Answer

Pseudostratified appears layered due to nuclei at different heights, but all cells touch the basement membrane

Question 16

Which of the following equations best represents the relationship between the probability of cancer ($P$) and age ($A$), given that cancer rates increase with age?

Accepted Answer

$P = kA$

Question 17

Which type of muscle tissue is found in the walls of hollow organs, contains a single nucleus per cell, and is non-striated?

Accepted Answer

Smooth muscle

Question 18

Which supporting connective tissue contains chondrocytes in lacunae and is avascular?

Accepted Answer

Cartilage

Question 19

Which of the following is NOT a function of connective tissue?

Accepted Answer

Control of permeability

Question 20

A tissue sample contains irregularly shaped cells with many long projections, including some several centimeters long. Which type of cell is this most likely to be?

Accepted Answer

Neuron
