Question 1

What type of epithelium is found in the mucous membrane of the rectum?&#10;A) transitional epithelium&#10;B) simple columnar&#10;C) pseudostratified ciliated columnar&#10;D) stratified squamous epithelium

Accepted Answer

Stratified squamous epithelium is found in the mucous membrane of the rectum.

Question 2

All of the following are types of serous membranes in the body EXCEPT ________.&#10;A) thoracic&#10;B) pleura&#10;C) pericardium&#10;D) peritoneum

Accepted Answer

Thoracic is not a type of serous membrane in the body. The other three options (pleura, pericardium, and peritoneum) are all examples of serous membranes.

Question 3

What type of membrane lines joint cavities?&#10;A) synovial&#10;B) serous&#10;C) mucous&#10;D) cutaneous

Accepted Answer

Synovial membranes line joint cavities and secrete synovial fluid, which provides lubrication and nutrients to the joints. Serous membranes line body cavities that do not open to the outside, such as the pleura, peritoneum, and pericardium. Mucous membranes line body cavities that open to the outside, such as the respiratory and digestive tracts. Cutaneous membranes refer to the skin.

Question 4

How many layers are found in a serous membrane?&#10;A) four&#10;B) one&#10;C) three&#10;D) two

Accepted Answer

A serous membrane is composed of two layers: a visceral layer that covers an organ and a parietal layer that lines the body cavity. Therefore, there are only two layers found in a serous membrane.

Question 5

All of the following are one of the major types of membranes EXCEPT ________.&#10;A) synovial&#10;B) serous&#10;C) mucous&#10;D) integument

Accepted Answer

The three major types of membranes are synovial, serous, and mucous. Integument is not a type of membrane, but rather refers to the skin as a whole.

Question 6

What type of epithelial tissue makes up the cutaneous membrane?&#10;A) pseudostratified epithelium&#10;B) simple epithelium&#10;C) stratified epithelium&#10;D) transitional epithelium

Accepted Answer

The cutaneous membrane is made up of stratified epithelium, specifically keratinized stratified squamous epithelium. This type of tissue provides protection against physical and chemical damage, as well as helping to regulate water loss.

Question 7

The ________ layer of a serous membrane is in direct contact with an organ.&#10;A) mesothelium&#10;B) visceral&#10;C) parietal&#10;D) none of the above

Accepted Answer

The visceral layer of a serous membrane is the layer that is in direct contact with an organ, while the parietal layer lines the body cavity. The mesothelium refers to the type of cells that make up the serous membrane, and is present in both the visceral and parietal layers.

Question 8

What type of epithelium occurs in the mucous membrane of the trachea?&#10;A) transitional epithelium&#10;B) stratified squamous epithelium&#10;C) pseudostratified ciliated columnar&#10;D) simple columnar cells

Accepted Answer

Pseudostratified ciliated columnar epithelium is found in the mucous membrane of the trachea. This type of epithelium appears stratified due to the uneven heights of the cells, but all cells are anchored to the basement membrane and thus it is classified as simple epithelium. Additionally, the presence of cilia on the epithelial cells helps to move mucus and debris out of the respiratory tract.

Question 9

All of the following are components of mucin EXCEPT ________.&#10;A) water&#10;B) salts&#10;C) white blood cells&#10;D) red blood cells

Accepted Answer

Mucin is a key component of mucus, primarily composed of water, salts, and various proteins, but not red blood cells. Red blood cells are components of blood, not mucin.

Question 10

The simple columnar cells that make up the mucous membrane in the small intestine live for approximately ________.&#10;A) 48 days&#10;B) 48 hours&#10;C) 24 hours&#10;D) 24 days

Accepted Answer

The simple columnar cells that make up the mucous membrane in the small intestine have a short lifespan and are replaced approximately every 48 hours.
