Question 1

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

Accepted Answer

Covering body surfaces and lining cavities to provide protection, absorption, filtration, and secretion

Question 2

A sample of tissue is observed under a microscope. It consists of a single layer of tall, column-shaped cells with nuclei located near the base. Which type of epithelial tissue is this most likely to be?

Accepted Answer

Simple columnar epithelium

Question 3

Which specialized characteristic of epithelial tissue allows it to rapidly repair itself after injury?

Accepted Answer

Regeneration

Question 4

A gland that secretes its product by exocytosis shortly after it is produced is classified as which type of gland?

Accepted Answer

Merocrine

Question 5

Which of the following is a correct description of the basement membrane in epithelial tissue?

Accepted Answer

It is a nonliving adhesive material composed largely of glycoproteins that separates the epithelium from underlying connective tissue

Question 6

Which type of connective tissue fiber is most abundant and provides high tensile strength?

Accepted Answer

Collagen fibers

Question 7

A patient has a disorder affecting the extracellular matrix of connective tissue, resulting in poor resistance to tension and stretching. Which component is most likely deficient?

Accepted Answer

Collagen fibers

Question 8

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

Accepted Answer

Endocrine glands secrete hormones directly into the blood; exocrine glands secrete products onto body surfaces or into body cavities via ducts

Question 9

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

Accepted Answer

$$n = 1$$ \rightarrow$$ simple epithelium; n$$ \u003e 1$$ \rightarrow$$ stratified epithelium

Question 10

A tissue sample from the urinary bladder shows cells that change shape and appear cuboidal when relaxed and squamous when stretched. What type of epithelium is this?

Accepted Answer

Transitional epithelium

Question 11

Which connective tissue subtype is characterized by a matrix containing densely packed collagen fibers oriented in one direction, providing great resistance to pulling forces?

Accepted Answer

Dense regular connective tissue

Question 12

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

Accepted Answer

Absorption of nutrients

Question 13

A multicellular exocrine gland with secretory cells forming a flask-like sac is classified as which type?

Accepted Answer

Alveolar

Question 14

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

Accepted Answer

It allows rapid diffusion and filtration due to its thin, flat structure

Question 15

Which connective tissue cell type is responsible for synthesizing the matrix and fibers in cartilage?

Accepted Answer

Chondrocyte

Question 16

A glandular epithelial cell releases its product by accumulating it until the cell ruptures, destroying the cell. What type of secretion is this?

Accepted Answer

Holocrine

Question 17

Which of the following is a major function of adipose tissue?

Accepted Answer

Storing energy and insulating the body

Question 18

Which property of connective tissue allows it to withstand great tension and endure abuse?

Accepted Answer

Extracellular matrix

Question 19

Which of the following best describes the function of reticular fibers in connective tissue?

Accepted Answer

Form supportive networks around blood vessels and support soft tissue organs

Question 20

A tissue sample contains cells with microvilli on their apical surface, arranged in a single layer of tall cells. Which function is most likely associated with this tissue?

Accepted Answer

Absorption and secretion
