Question 1

Which of the following best describes the primary function of epithelial tissue in the human body?

Accepted Answer

Covers and lines surfaces, providing protection and regulating permeability.

Question 2

A patient suffers a severe burn that destroys the epithelial tissue of the skin. Which key feature of epithelial tissue is most directly compromised, increasing the risk of infection?

Accepted Answer

Cellularity (tightly packed with junctions)

Question 3

Which type of epithelial tissue would you expect to find lining the urinary bladder, and what is its primary function?

Accepted Answer

Transitional; allows for stretching

Question 4

A biopsy reveals a tissue sample with multiple layers of flat cells. Which type of epithelial tissue is this, and where is it most likely found?

Accepted Answer

Stratified squamous; skin (epidermis)

Question 5

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

Accepted Answer

Cartilage lacks blood vessels, while bone is highly vascularized.

Question 6

A patient is diagnosed with a disorder affecting the matrix of connective tissue. Which of the following functions is most likely to be impaired?

Accepted Answer

Structural support and storage of energy

Question 7

Which type of muscle tissue is responsible for voluntary movement, and what is a distinguishing microscopic feature?

Accepted Answer

Skeletal muscle; long, striated, multinucleated fibers

Question 8

During a heart attack, cardiac muscle cells are damaged. Which unique feature of cardiac muscle helps coordinate the contraction of the heart?

Accepted Answer

Intercalated discs

Question 9

Which of the following best describes the function of neuroglial cells in nervous tissue?

Accepted Answer

Support, protect, and maintain the environment for neurons

Question 10

A patient has a genetic defect affecting the production of collagen fibers in connective tissue. Which of the following symptoms would most likely result?

Accepted Answer

Weakened structural support in skin, bones, and tendons

Question 11

Which of the following equations best represents the relationship between surface area ($A$), diffusion rate ($D$), and thickness ($T$) in simple squamous epithelium, assuming all other factors are constant?

Accepted Answer

$D = \frac{A}{T}$

Question 12

A patient with a damaged basement membrane in the lungs would most likely experience which of the following problems?

Accepted Answer

Impaired diffusion of gases due to loss of epithelial attachment

Question 13

Which of the following best explains why smooth muscle is found in the walls of blood vessels?

Accepted Answer

It contracts involuntarily to regulate vessel diameter and blood flow.

Question 14

A nerve cell (neuron) is damaged and cannot transmit signals away from the cell body. Which part of the neuron is most likely affected?

Accepted Answer

Axon

Question 15

Which of the following is a key difference between endocrine and exocrine glands, both derived from epithelial tissue?

Accepted Answer

Endocrine glands secrete hormones directly into the bloodstream, while exocrine glands secrete into ducts.

Question 16

A patient with a genetic disorder affecting the regeneration of epithelial tissue would most likely have difficulty with which of the following?

Accepted Answer

Healing after injury

Question 17

Which of the following best describes the function of adipose tissue, a type of connective tissue?

Accepted Answer

Stores energy and insulates the body

Question 18

A patient presents with muscle weakness and involuntary contractions in the digestive tract. Which type of muscle tissue is most likely affected?

Accepted Answer

Smooth muscle

Question 19

Which of the following scenarios best illustrates the function of stratified squamous epithelium?

Accepted Answer

Protection against abrasion on the surface of the skin

Question 20

A patient with a spinal cord injury loses the ability to transmit sensory information to the brain. Which type of nervous tissue cell is primarily responsible for this function?

Accepted Answer

Sensory neuron
