Accepted Answer

Glandular epithelium

Question 3

Which of the following is a key structural characteristic of connective tissue that distinguishes it from epithelial tissue?

Accepted Answer

Abundant extracellular matrix with scattered cells

Question 4

A histology slide shows tissue with elongated, multinucleated cells and obvious striations. Which type of muscle tissue is this?

Accepted Answer

Skeletal muscle

Question 5

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

Accepted Answer

Cartilage lacks a direct blood supply, limiting nutrient delivery

Question 6

Which equation best represents the relationship between the surface area ($$A) $$and volume ($$V) of a $$cube-shaped epithelial cell with side length $$l$$?

Accepted Answer

$$A = 6l^2$, V$$ = $$l^3$$

Question 7

A biopsy reveals a tissue type with the following features: cells are arranged in a single layer, are tall and column-shaped, and nuclei are located near the base. Which tissue is this?

Accepted Answer

Simple columnar epithelium

Question 8

Which of the following best describes the main function of nervous tissue?

Accepted Answer

Transmission of electrical signals for communication and control

Question 9

A patient has a genetic disorder affecting the production of collagen fibers. Which tissue type is most likely to be structurally compromised?

Accepted Answer

Connective tissue

Question 10

Which of the following is a correct comparison between endocrine and exocrine glands?

Accepted Answer

Endocrine glands secrete hormones directly into the bloodstream; exocrine glands secrete their products into ducts

Question 11

Which of the following best explains why stratified squamous epithelium is found in the skin?

Accepted Answer

It provides protection against abrasion and pathogens

Question 12

A tissue sample is observed to have intercalated discs and branching cells. Which tissue is this, and what is its primary function?

Accepted Answer

Cardiac muscle; pumping blood throughout the body

Question 13

Which of the following connective tissues is classified as a fluid connective tissue and what is its main function?

Accepted Answer

Blood; transport of gases, nutrients, and wastes

Question 14

Which of the following best describes the role of mesenchyme in connective tissue development?

Accepted Answer

It is the embryonic tissue from which all connective tissues are derived

Question 15

A patient suffers a spinal cord injury that disrupts the function of nervous tissue. Which of the following is most likely to be affected?

Accepted Answer

Ability to transmit sensory and motor signals

Question 16

Which of the following best explains why simple squamous epithelium is found lining the alveoli of the lungs?

Accepted Answer

It allows for rapid diffusion of gases due to its thinness

Question 17

Which of the following is a function shared by both connective and epithelial tissues?

Accepted Answer

Secretion of substances

Question 18

A tissue sample is composed of spindle-shaped cells with a single central nucleus and no visible striations. Which tissue is this, and where is it commonly found?

Accepted Answer

Smooth muscle; walls of hollow organs such as intestines and blood vessels

Question 19

Which of the following best describes the main difference between loose and dense connective tissue?

Accepted Answer

Loose connective tissue has more cells and fewer fibers, while dense connective tissue has more fibers and fewer cells

Question 20

A patient is diagnosed with a disease that destroys the myelin sheath of neurons. Which function is most likely to be impaired?

Accepted Answer

Rapid transmission of electrical impulses
