Q: Which of the following equations best represents the relationship between the components of the extracellular matrix (ECM) in connective tissue?

$$\text{ECM} = \text{Ground Substance} + \text{Protein Fibers}$$

Question 1

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

Accepted Answer

Endocrine glands secrete hormones into the bloodstream without ducts, while exocrine glands secrete their products onto body surfaces or into organ lumens using ducts.

Question 2

A tissue sample from the lining of blood vessels is most likely to be which type of epithelial tissue?

Accepted Answer

Simple squamous epithelium

Question 3

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

Accepted Answer

Cushioning organs and providing flexible support

Question 4

Which method of exocrine gland secretion involves the entire cell rupturing to release its product?

Accepted Answer

Holocrine

Question 5

A gland that consists of a single, mucus-secreting cell scattered among columnar epithelial cells is called a:

Accepted Answer

Goblet cell

Question 6

Which connective tissue type is specialized for energy storage, insulation, and shock absorption?

Accepted Answer

Adipose tissue

Question 7

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

Accepted Answer

It consists of ground substance and protein fibers, with more ECM than cells.

Question 8

Which of the following is a characteristic unique to transitional epithelium?

Accepted Answer

Ability to stretch and change shape

Question 9

A patient presents with a torn tendon. Which connective tissue is primarily affected?

Accepted Answer

Dense regular connective tissue

Question 10

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

Accepted Answer

Secreting digestive enzymes

Question 11

Which of the following equations best represents the relationship between the components of the extracellular matrix (ECM) in connective tissue?

Accepted Answer

$$	ext{ECM} = 	ext{Ground Substance} + 	ext{Protein Fibers}$$

Question 12

Which of the following best describes the secretion mechanism of mammary glands?

Accepted Answer

Apocrine secretion

Question 13

Which of the following tissues would you expect to find lining the urinary bladder, allowing it to stretch as it fills?

Accepted Answer

Transitional epithelium

Question 14

Which of the following is a key difference between epithelial and connective tissues?

Accepted Answer

Connective tissues have more ECM than cells, while epithelial tissues have closely packed cells with little ECM.

Question 15

Which of the following best describes the function of reticular connective tissue?

Accepted Answer

Forms a supporting framework for organs such as the spleen and lymph nodes

Question 16

Which of the following is a characteristic of simple columnar epithelium?

Accepted Answer

Single layer of tall, rectangular cells

Question 17

Which of the following is a correct pairing of gland type and secretion method?

Accepted Answer

Sebaceous gland – holocrine secretion

Question 18

Which of the following best explains why goblet cells are considered exocrine glands even though they lack ducts?

Accepted Answer

They secrete their product (mucin) onto epithelial surfaces, not into the blood.

Question 19

A tissue sample shows parallel bundles of collagen fibers with fibroblasts in between. Which tissue is this most likely to be?

Accepted Answer

Dense regular connective tissue

Question 20

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

Accepted Answer
