Deck 17: Basic Tissues

Question 1

Epithelial cells that grow downward into the connective tissue form

A) transitional epithelium
B) blood vessels
C) glands
D) stratum granulosum

Answer 1

C
Most of the glands of the body are developed from epithelium.As the epithelium develops,some of the basal cells begin to grow downward into underlying connective tissue.A hollow cord of epithelial tissue is formed that later becomes a gland.

Question 2

Exocrine glands are considered ductless because although they secrete glandular products,their ducts are lost after development of the gland.

A) Both the statement and the reason are correct and related.
B) Both the statement and the reason are correct but are NOT related.
C) The statement is correct,but the reason is NOT correct.
D) The statement is NOT correct,but the reason is correct.
E) NEITHER the statement NOR the reason is correct.

Answer 2

E
Exocrine glands transport glandular secretions via a duct system;they are NOT ductless.However endocrine glands lose their ducts after development of the gland and are considered ductless.

Question 3

The MOST common type of multiple-layered epithelium is stratified squamous epithelium.Stratified is synonymous with transitional.

A) Both statements are true.
B) The first statement is true;the second statement is false.
C) The first statement is false;the second statement is true.
D) Both statements are false.

Answer 3

B
Stratified squamous epithelium,the covering of the body and the oral mucosa,is the most common type of stratified epithelium.In soft tissue terminology,stratified is a term used to describe multilayered tissues.Transitional epithelium,another stratified tissue type,has the capability to change thickness and appearance as needed.It is a major tissue of the urinary system and is not synonymous with stratified squamous epithelium.

A) Both statements are true.
B) The first statement is true;the second statement is false.
C) The first statement is false;the second statement is true.
D) Both statements are false.

A) Transitional epithelium changes in thickness and appearance as the need arises.
B) Stratified cuboidal epithelium is only found in select locations.
C) Stratified columnar epithelium is commonly found throughout the body.
D) Stratified squamous epithelium is the most common type of epithelium.

Question 20

Mitochondria are significantly responsible for metabolism because these organelles produce and regulate energy.

A) Both the statement and the reason are correct and related.
B) Both the statement and the reason are correct but are NOT related.
C) The statement is correct,but the reason is NOT correct.
D) The statement is NOT correct,but the reason is correct.
E) NEITHER the statement NOR the reason is correct.
