Question 1

Which of the following best describes the difference between mucous and serous membranes?

Accepted Answer

Mucous membranes line cavities that open to the exterior and have an epithelial layer with goblet cells, while serous membranes line closed cavities and secrete serous fluid.

Question 2

Accepted Answer

Respiratory system

Question 3

Which of the following statements about the lamina propria is correct?

Accepted Answer

It is a vascular connective tissue layer that nourishes the epithelial cells of mucous membranes.

Question 4

Which membrane type is found lining the inside of the knee joint and what is its main tissue component?

Accepted Answer

Synovial membrane; areolar connective tissue

Question 5

A surgeon is operating in the abdominal cavity and must cut through the serous membrane covering the intestines. Which specific membrane is being incised?

Accepted Answer

Visceral peritoneum

Question 6

Which of the following best explains why synovial membranes are NOT considered organs?

Accepted Answer

They are composed of only one tissue type, not two or more.

Question 7

Which of the following is TRUE regarding the cutaneous membrane?

Accepted Answer

It consists of stratified squamous epithelium (epidermis) and areolar plus dense irregular connective tissue (dermis).

Question 8

Which of the following correctly matches the membrane with its location?

Accepted Answer

Pleura – lines the thoracic cavity and covers the lungs

Question 9

A patient with a severe respiratory infection has damage to the goblet cells in their respiratory tract. Which membrane is most affected?

Accepted Answer

Mucous membrane

Question 10

Which of the following best describes the relationship between the parietal and visceral layers of a serous membrane?

Accepted Answer

The parietal layer lines the cavity wall, and the visceral layer covers the organ; both secrete serous fluid into the cavity between them.

Question 11

Which of the following is NOT a function of serous fluid secreted by serous membranes?

Accepted Answer

Nourishing the epithelial cells of mucous membranes

Question 12

Which of the following body cavities contains the urinary bladder?

Accepted Answer

Pelvic cavity

Question 13

A patient with peritonitis has inflammation of which structure?

Accepted Answer

The serous membrane lining the abdominal cavity and covering abdominal organs

Question 14

Which of the following is a characteristic of the epithelial layer of mucous membranes?

Accepted Answer

It is in direct contact with the lumen of the organ.

Question 15

Which of the following best explains why organs are considered to be composed of two or more tissue types?

Accepted Answer

Organs may contain all four major tissue types: epithelial, connective, muscle, and nervous.

Question 16

Accepted Answer

Areolar and dense irregular connective tissue

Question 17

Which of the following is TRUE regarding the dorsal body cavity?

Accepted Answer

It houses the brain and spinal cord.

Question 18

Which of the following best describes the tissue composition of serous membranes?

Accepted Answer

Simple epithelium bound to areolar connective tissue

Question 19
