Question 2

Which of the following best describes the function of simple squamous epithelium and its typical location?

Accepted Answer

Question 3

A tissue sample shows cells with cilia and goblet cells arranged in a single layer that appears stratified. Which tissue is most likely being observed?

Accepted Answer

Pseudostratified ciliated columnar epithelium

Question 4

Which equation best represents the relationship between the number of cell layers ($$n) $$and the permeability ($$P) of an $$epithelial tissue, assuming permeability decreases exponentially with more layers?

Accepted Answer

$$P = P_0$ \cdot e$$^{-kn}$$

Question 5

Which connective tissue type is characterized by a matrix rich in collagen fibers, fibroblast cells, and is found in tendons and ligaments?

Accepted Answer

Dense regular connective tissue

Question 6

A patient with a deficiency in mast cells would most likely experience problems with which function?

Accepted Answer

Initiating immune responses and inflammation

Question 7

Which of the following best distinguishes microvilli from cilia in epithelial tissues?

Accepted Answer

Microvilli increase surface area for absorption, while cilia move substances across the cell surface.

Question 8

Which connective tissue subtype contains lacunae, chondrocytes, and a matrix with visible elastic fibers, and is found in the external ear?

Accepted Answer

Elastic cartilage

Question 9

Which equation describes the total number of nuclei ($$N) in a $$skeletal muscle fiber, given the fiber length ($$L) $$and average nuclei per unit length ($$n$$)?

Accepted Answer

$$N = n \cdot L$$

Question 10

Which of the following is a distinguishing feature of cardiac muscle tissue compared to skeletal muscle tissue?

Accepted Answer

Presence of intercalated discs

Question 11

Which cell type is responsible for producing the extracellular matrix in connective tissue proper?

Accepted Answer

Fibroblast

Question 12

A histological slide shows spindle-shaped, uni-nucleated, non-striated cells. Which muscle tissue is most likely present?

Accepted Answer

Smooth muscle

Question 13

Which of the following best describes the function of neuroglia in nervous tissue?

Accepted Answer

Support and protect neurons

Question 14

Which equation best represents the total volume ($$V) of $$ground substance in a connective tissue sample, given the tissue's total volume ($$T) $$and the proportion of ground substance ($$g$$)?

Accepted Answer

$$V = g \cdot T$$

Question 15

Which epithelial tissue is specialized for stretching and is found lining the urinary bladder?

Accepted Answer

Transitional epithelium

Question 16

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

Accepted Answer

Storing fat

Question 17

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

Accepted Answer

Exocrine glands secrete products onto epithelial surfaces via ducts; endocrine glands release hormones directly into the bloodstream.

Question 18

Which connective tissue subtype is responsible for hematopoiesis and is found within the trabeculae of spongy bone?

Accepted Answer

Hematopoietic tissue

Question 19

Which of the following structures is NOT typically found in a neuron?

Accepted Answer

Fibroblast

Question 20

A tissue sample from the skin shows multiple layers of cells, with the outermost layer composed of dead, flattened cells containing keratin. Which tissue is most likely present?

Accepted Answer

Keratinized stratified squamous epithelium
