Flashcards in Epithelial Tissue Deck (35):
1

What does keratinized stratified squamous epithelia form?

Surface of the skin

2

What does non keratinized stratified squamous epithelia form?

Lining of mouth, anus, and vagina

3

What does simple cuboidal epithelia form?

Portions of kidney tubules; also found in various glands and ducts

4

Where is stratified cuboidal epithelia?

Lining if some ducts. Rare

5

Where is transitional epithelia?

Urinary bladder, renal pelvis, and ureters

6

Where is simple columnar epithelia?

Stomach, intestinal lining, and many excretory ducts

7

Where is pseudostratified ciliated columnar epithelia?

Trachea, nasopharynx, bronchi, and portions of male reproductive tract. Possess cilia

8

Where is stratified columnar epithelia?

Ducts of salivary glands, small areas of the pharynx, epiglottis, anus, mammary glands, and urethra

9

What are functions of simple squamous epithelium?

Reduce friction, control permeability, perform absorption and secretion

10

What are functions of simple cuboidal epithelia?

Diffusion and limited protection

11

What are functions of simple columnar epithelium?

Secretion, absorption, protection

12

What are functions of stratified squamous epithelium?

Protection where mechanical stresses are severe

13

What are functions of stratified cuboidal epithelium?

Protection, secretion, and absorption

14

What are functions of stratified columnar epithelium?

Protection

15

Serous glands

Secrete a watery solution that usually contains enzymes, such as salivary amylase in saliva

16

Mucous gland

Exocrine gland that secretes mucins which absorb water to form slippery mucus, such as those in saliva

17

Mixed exocrine glands

Contain more than one type of gland cell and may produce two different exocrine secretions (could be serous or mucous)

18

How endocrine glands release their secretions?

Exocytosis from the gland cells into the fluid surrounding the cell

19

Unicellular glands

Individual secretory cells that secrete mucins. There are two types goblet and mucous cells

20

Where are mucous cells found and where are they?

Unicellular gland cells that are found in pseudostratified ciliated epithelia.

21

Where are goblet cells and what are they?

Unicellular gland cells. They are scattered among simple columnar epithelium of the small and large intestine

22

Secretory sheet

Simplest multicellular exocrine gland. Glandular cells dominate the epithelium and release their secretions into an inner compartment

23

What is an example of a secretory sheet?

Mucus secreting cells in the stomach

24

What's an example of a simple tubular gland

Intestinal glands. Multicellular

25

What is an example of simple coiled tubular gland?

Merocrine sweat glands

26

What are examples of simple branched tubular glands?

Gastric glands, mucous glands of esophagus, tongue, and duodenum

27

What is an example of a simple alveolar gland?

Not found in adults but is a stage in development of simple branched glands

28

What is an example of a simple branched alveolar gland?

Sebaceous glands

29

What is an example of a compound tubular gland?

Mucous glands (in oral cavity), bulbo-urethral glands (male reproductive system), testes (seminiferous tubules)

30

What is an example of a compound alveolar gland?

Mammary glands

31

What is an example of compound tubuloalveolar gland?

Salivary glands, glands of respiratory passages, pancreas

32

Merocrine secretion

Method of glandular epithelial cell secretion. Exocytosis puts products onto surface of the cell. Ex: serous cells of salivary glands

33

Apocrine secretion

Method of glandular epithelial cell secretion in which the cytoplasm is shed. Ex: Lactiferous cells of the mammary gland

34

Holocrine secretion

Type of glandular epithelial cell secretion. Destroys gland cell by build up of secretory product (ex: sebaceous gland cells)

35

What structures does simple squamous epithelia form?

Alveoli of the lung, inner lining of the cornea of the eye, mesothelial lining of ventral body cavities, and endothelial lining of blood vessels
