Question 1

Which type of epithelial tissue is best suited for rapid diffusion of gases in the lungs, and what structural feature enables this function?

Accepted Answer

Simple squamous epithelium; single layer of flat cells

Question 2

A patient suffers a deep cut that damages the tissue responsible for resisting tension in multiple directions. Which connective tissue is most likely affected?

Accepted Answer

Dense irregular connective tissue

Question 3

Which of the following best describes the main function and location of pseudostratified ciliated columnar epithelium?

Accepted Answer

Secretion and movement of mucus in the trachea

Question 4

A biopsy reveals tissue with multiple layers of flat cells at the surface and cuboidal cells at the base. Which tissue is this, and what is its primary function?

Accepted Answer

Stratified squamous epithelium; protection against abrasion

Question 5

Which muscle tissue type is striated, contains intercalated discs, and is involuntary?

Accepted Answer

Cardiac muscle

Question 6

A histology slide shows large cells with multiple peripheral nuclei and visible striations. Which muscle type is this, and is it voluntary or involuntary?

Accepted Answer

Skeletal muscle; voluntary

Question 7

Which connective tissue type stores energy, insulates against heat loss, and cushions organs?

Accepted Answer

Adipose tissue

Question 8

A patient with a torn tendon has damaged which type of connective tissue, and what is its main structural protein?

Accepted Answer

Dense regular connective tissue; collagen

Question 9

Which of the following best describes the function and location of transitional epithelium?

Accepted Answer

Stretching to accommodate fluctuation of volume in the urinary bladder

Question 10

A tissue sample contains neurons and glial cells. Which function is unique to neurons in this tissue?

Accepted Answer

Transmitting electrical impulses

Question 11

Which of the following equations best represents the relationship between force ($$F$$), cross-sectional area ($$A$$), and stress ($$\sigma) in $$tendons composed of dense regular connective tissue?

Accepted Answer

$$\sigma = \dfrac{F}{A}$$

Question 12

Which connective tissue type forms the stroma of lymphoid organs and what is its main fiber type?

Accepted Answer

Reticular connective tissue; reticular fibers

Question 13

A patient with a genetic defect in the production of cilia would most likely have impaired function in which tissue and organ?

Accepted Answer

Pseudostratified ciliated columnar epithelium in the trachea

Question 14

Which muscle tissue type is responsible for peristalsis in the digestive tract, and what is a key structural feature?

Accepted Answer

Smooth muscle; spindle-shaped cells without striations

Question 15

Which of the following best explains why stratified squamous epithelium is found in areas subject to abrasion, such as the skin and esophagus?

Accepted Answer

It provides a thick, protective barrier due to multiple cell layers

Question 16

A histological section of the spinal cord shows a central 'H' or butterfly-shaped zone. What type of cells are primarily found in this region, and what is their function?

Accepted Answer

Neurons; transmission of electrical signals

Question 17

Which of the following best describes the difference between simple columnar and stratified columnar epithelium?

Accepted Answer

Simple columnar consists of a single layer of tall cells; stratified columnar has several layers with columnar cells at the surface

Question 18

A patient with a connective tissue disorder has weak, easily damaged blood vessel walls. Which tissue and component are most likely deficient?

Accepted Answer

Elastic connective tissue; elastic fibers

Question 19

Which of the following best describes the arrangement and function of nuclei in cardiac muscle cells?

Accepted Answer

Single central nucleus; involuntary contraction

Question 20

Which tissue type is most likely to be involved in the rapid absorption of nutrients in the digestive tract, and what is a key structural adaptation?

Accepted Answer

Simple columnar epithelium; microvilli to increase surface area
