Module 4 Quiz Questions

Question 1

What is the function of the transitional epithelium?

Answer 1

To allow for the stretching if the epithelium without tearing.

Question 2

What 2 components make up an epithelial membrane?

Answer 2

An epithelial layer and an underlying layer of connective tissue.

Question 3

What is the unique feature of a cartilage as a type of connective tissue?

Answer 3

Cartilage generally lacks blood vessels and nerves.

Question 4

What is the major difference between the exocrine and endocrine glands?

Answer 4

Exocrine glands empty through ducts into an epithelial surface outside of the body or lumen of a hollow organ (sweat, oils). Endocrine glands empty hormones into the bloodstream.

Question 5

List the 4 major types of tissues and give the herbal function of each.

Answer 5

Epithelial (protection), connective (support), muscular (movement), nervous (transmit impulses).

Question 6

List 3 general functions of connective tissue.

Answer 6

Protection, support, binds organs together.

Question 7

The ground substance of connective tissue contains complex molecules, including ___ and within this material are 3 types of fibres called __ ___ ___. The most common cell type in areolar CT is the ___. A second cell type that functions in bacterial phagocytosis is called the ___. Other cells include ___, ___ and ___.

Answer 7

Intercellular material (hyaluronic acid).
Collagen, elastic and reticular.
Fibroblast.
Macrophage.
Mast cells, plasma cells and adipocytes.

Question 8

List the 3 functions of bone.

Answer 8

Support, protection, and movement.

Question 9

Complete the following table by naming a specific location where it can be found and it’s one specific function: adipose, dense regular CT, elastic CT, hyaline cartilage.

Answer 9

Adipose: the subcutaneous layer below the skin, support and protection. Dense reg c: tendons and ligaments, attachment. Elastic CT: arterial walls, lungs, allows stretching. Hyaline cartilage: nose, larynx, ends of long bones, allows flexibility and support, reduces friction, absorbs shock on joints.

Question 10

Describe the structure of the basement membrane.

Answer 10

Is made up of a cellular layer of collagen and glycoproteins called the basal lamina; often it is underlain with a layer of reticular fibres and glycoproteins called the reticular lamina.

Question 11

List the 3 types of muscle tissues and state whether they are under voluntary or involuntary control.

Answer 11

Skeletal (voluntary), cardiac (involuntary), smooth (involuntary).

Question 12

Nerve tissue is made up of 2 principal cell types:

Answer 12

Neurons, neuroglia

Answer 13

Covering the external body surface, lining body cavities, covering some of the internal organs.

Question 14

What is the function of the glandular epithelium?

Answer 14

Produces secretory products of the glands such as oils, sweat and hormones.

Question 15

For what function is simple squamous epithelium specialized?

Answer 15

Question 24

The serous membrane lining the thoracic cavity is called the ___; whereas the membrane lining the cavity containing the heart is called the ___.

Answer 24
