Question 1

Which of the following best describes the main function of simple squamous epithelium, and where is it most likely to be found?

Accepted Answer

Rapid exchange of substances; lining alveoli and blood vessels

Question 2

A patient suffers a severe burn that destroys the epidermis and underlying connective tissue. Which tissue type is LEAST likely to regenerate effectively, and why?

Accepted Answer

Cardiac muscle, because it is not regenerative

Question 3

Which of the following junctions allows for the direct passage of ions and small molecules between adjacent epithelial cells?

Accepted Answer

Gap junctions

Question 4

A gland that releases its product by the entire cell rupturing and disintegrating is classified as which type of exocrine gland?

Accepted Answer

Holocrine

Question 5

Which connective tissue fiber type is most responsible for providing high tensile strength to tissues such as tendons and ligaments?

Accepted Answer

Collagen fibers

Question 6

A biopsy of a patient’s esophagus reveals multiple layers of nonkeratinized cells. Which tissue type is this, and what is its primary function?

Accepted Answer

Stratified squamous epithelium; protection

Question 7

Which of the following best explains why cartilage heals poorly after injury?

Accepted Answer

It is avascular, so nutrients and cells for repair are limited

Question 8

Which of the following equations best represents the relationship between the number of cell layers ($$n) $$and the classification of epithelial tissue?

Accepted Answer

$$n = 1$$ for simple epithelium$

Question 9

A patient presents with swelling (edema) in the tissue between their muscles. Which connective tissue type is most likely involved, and what is its function?

Accepted Answer

Areolar connective tissue; universal packing and support

Question 10

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

Accepted Answer

Endocrine glands are ductless and secrete hormones into the blood; exocrine glands secrete products onto surfaces via ducts

Question 11

Which of the following is a characteristic unique to cardiac muscle tissue?

Accepted Answer

Intercalated discs and gap junctions

Question 12

A tissue sample from the urinary bladder shows cells that change shape when stretched. What is the name of this tissue, and what is its function?

Accepted Answer

Transitional epithelium; allows stretching and recoil

Question 13

Which of the following best describes the function of the basement membrane in epithelial tissue?

Accepted Answer

It anchors the epithelium to underlying connective tissue and acts as a selective filter

Question 14

Which of the following best explains why blood is classified as a connective tissue?

Accepted Answer

It consists of cells surrounded by a nonliving extracellular matrix (plasma)

Question 15

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

Accepted Answer

Tensile strength in connective tissues

Question 16

Which of the following best describes the process of tissue repair after injury?

Accepted Answer

Inflammation sets the stage, organization restores blood supply, and regeneration/fibrosis effect permanent repair

Question 17

Which of the following equations best represents the relationship between the number of nuclei ($$n) $$and the type of muscle tissue?

Accepted Answer

$$n \u003e 1$$ for skeletal muscle$

Question 18

Which of the following is a function of neuroglia (glial cells) in nervous tissue?

Accepted Answer

Support and protect neurons

Question 19

A patient with a mutation affecting the formation of tight junctions in their intestinal epithelium would most likely experience which of the following?

Accepted Answer

Uncontrolled passage of substances between cells

Question 20

Which of the following best describes the difference between mucous and serous membranes?

Accepted Answer

Mucous membranes line body cavities open to the exterior; serous membranes line closed body cavities
