Question 1

Which of the following is NOT a function of simple epithelium?&#10;A) diffusion&#10;B) protection&#10;C) secretion&#10;D) absorption

Accepted Answer

One of the main functions of simple epithelium is protection, so option B is not correct. The other options, diffusion, secretion, and absorption, are all functions of simple epithelium.

Question 2

Which type of epithelium lines the nasal cavity, the trachea, bronchi, and parts of the male reproductive tract?&#10;A) transitional epithelium&#10;B) pseudostratified columnar epithelium&#10;C) stratified squamous epithelium&#10;D) stratified cuboidal epithelium

Accepted Answer

Pseudostratified columnar epithelium lines the respiratory tract and parts of the male reproductive tract.

Question 3

This &#34;category&#34; of epithelia is found in areas exposed to abrasion and friction.&#10;A) transitional epithelium&#10;B) stratified epithelia&#10;C) simple epithelia&#10;D) pseudostratified

Accepted Answer

Stratified epithelia are composed of multiple layers of cells and are found in areas that are exposed to mechanical stress, such as skin and the lining of the mouth and esophagus. Transitional epithelium is found in organs that need to expand and contract, such as the bladder. Simple epithelia is composed of a single layer of cells and is found in areas where absorption or secretion are the primary functions, such as the lining of the intestines or lungs. Pseudostratified epithelium is found in the respiratory system and appears to be layered but is actually composed of a single layer of cells.

Question 4

Which type of epithelium is found lining the urinary bladder?&#10;A) stratified cuboidal epithelium&#10;B) stratified columnar epithelium&#10;C) transitional epithelium&#10;D) pseudostratified columnar epithelium

Accepted Answer

The urinary bladder is lined by transitional epithelium, which is designed to accommodate changes in volume as the bladder fills and empties. This tissue has the ability to stretch and flatten without tearing, providing a protective barrier against underlying tissues.

Question 5

Which of the following is NOT a major category of tissue in the body?&#10;A) bone&#10;B) connective&#10;C) epithelial&#10;D) muscle

Accepted Answer

Although bone is a type of connective tissue, it is not considered a major category of tissue in the body. The four major categories of tissue are epithelial, connective, muscle, and nervous.

Question 6

Which type of epithelium is uncommon and is found only in the ducts of certain sweat glands?&#10;A) stratified columnar epithelium&#10;B) stratified squamous epithelium&#10;C) stratified cuboidal epithelium&#10;D) none of the above

Accepted Answer

Stratified cuboidal epithelium is uncommon and is found only in the ducts of certain sweat glands. Stratified columnar and stratified squamous epithelium are more common and found in various places throughout the body.

Question 7

Which type of epithelium when viewed under a microscope appears to have cube-shaped cells organized into rings to form ducts and tubules?&#10;A) stratified squamous epithelium&#10;B) simple cuboidal epithelia&#10;C) simple squamous epithelium&#10;D) simple columnar epithelium

Accepted Answer

Simple cuboidal epithelium have cells that appear cube-shaped and are organized into rings to form ducts and tubules, such as in the kidneys and glands. Stratified squamous epithelium is found in the skin and consists of multiple layers of flattened cells. Simple squamous epithelium is thin and flat, found in areas like the lining of blood vessels and lungs. Simple columnar epithelium consists of tall, thin cells found in the intestines and stomach.

Question 8

What type of epithelium appears to be two layers thick and looks like a doughnut?&#10;A) pseudostratified columnar&#10;B) stratified squamous epithelium&#10;C) stratified columnar epithelium&#10;D) stratified cuboidal epithelium

Accepted Answer

The answer of What type of epithelium appears to be...

Question 9

What protein does stratified epithelia cells produce?&#10;A) tubulin&#10;B) keratin&#10;C) myosin&#10;D) actin

Accepted Answer

Stratified epithelia cells are found in layers, such as the skin and lining of the mouth. These cells produce keratin, a tough fibrous protein that provides protection and waterproofing for the body.

Question 10

Which type of epithelium is found in parts of mammary glands?&#10;A) transitional epithelium&#10;B) stratified columnar epithelium&#10;C) stratified cuboidal epithelium&#10;D) stratified squamous epithelium

Accepted Answer

Question 11

The functions of the epithelia include all of the following, EXCEPT ________.&#10;A) absorption&#10;B) providing physical protection&#10;C) storing energy reserves&#10;D) controlling permeability

Question 12

Epithelial tissue ________.&#10;A) has two attached surfaces&#10;B) is avascular&#10;C) does not have cell junctions&#10;D) none of the above

Question 13

Epithelia are classified and identified by ________ and ________.&#10;A) number of cell layers; function&#10;B) number of cell layers; general shape&#10;C) function; general shape&#10;D) none of the above

Accepted Answer

The answer of Epithelia are classified and identified by ________...

Question 14

Which type of epithelium lines the blood vessels and the heart chambers, and is also called the endothelium?&#10;A) simple cuboidal epithelium&#10;B) simple squamous epithelium&#10;C) simple columnar epithelium&#10;D) none of the above

Question 15

What type of epithelium lines most of the digestive tract?&#10;A) stratified squamous epithelium&#10;B) simple columnar&#10;C) simple squamous epithelium&#10;D) simple cuboidal epithelium

Accepted Answer
