1
Q

epthelial special characteristic - polarity

A

apical-basal polarity: an upper free surface exposed to environment or cavity of an internal organ, and a lower attached to a basal surface.

2
Q

epthelial special characteristic - specialized contacts

A

Tight, gap and demosomes junctions (barrier/communication/structure integrity)

3
Q

epthelial special characteristic - supported by connective tissue

A

always! Supported by connective tissue

4
Q

epthelial special characteristic - avascular but innervated

A

contains no blood vessels, but is supplied by nerve fibers.

5
Q

epthelial special characteristic - regeneration

A

highly regenerative (mitosis)

6
Q

epthelial special characteristic - cellularity

A

Tightly packed cells, like a sheet

7
Q

Simple squamous - function/location

A

Diffusion/Filtration. in sites where protection is not important,

secretes lubricant in serosae —-

kidney glomeruli, air sacs of lungs, lining of heart, blood vessels, lymphatic vessels, serosae

8
Q

simple cuboidal - function/location

A

secretion and some absorption —-

kidney tubules, ducts and secretory portions of small glands, ovary surface

9
Q

Simple columnar - function/location

A

absorption, secretion of mucus, enzymes (ciliated type propels mucus or reproductive cells)

ciliated: lines small bronchi and uterine tubes, regions of uterus
nonciliated: digestive tract, gallbladder, excretory ducts of some glands

10
Q

stratified squamous - function/location

A

Protects underlying tissue (from abrasion) —

skin, mouth, esophagus, vagina

11
Q

pseudostratified columnar - function/location

A

secrete substances, particularly mucus, propulsion of mucus by cilary action —-

Ciliated: lining the trachea, upper respiratory tract

Nonciliated: sperm carrying ducts, ducts of large glands

12
Q

transitional - function/location

A

allow stretching —-

ureters, bladder, part of urethra

13
Q

Endothelium

A

Single layer of simple squamous cells that line the walls of the heart, blood vessels, and lymphatic vessels

14
Q

Mesothelium

A

Epithelium found in serous membranes lining the ventral body cavity and covering its organs

15
Q

Merocrine

A

glands that produce secretions intermittently

16
Q

Holocrine

A

glands that accumulate their secretions within their cells, secretions are discharged only upon rupture and death of the cell

17
Q

Apocrine

A

producing a fluid secretion by pinching off the apex of the cellreleasing the secretory granules and a small amount of cytoplasm

18
Q

Covering and lining epithelium

A

forms the outer layer of the skin, dips into and lines the open cavities of the urogenital, digestive, and respiratory systems; and covers the walls and organs of the closed ventral body cavity

19
Q

glandular epithelium

A

fashions the glands of the body

20
Q

Collagen?

A

Made from the protein, collagen, bundled into thick cords, tough

21
Q

Elastic?

A

Made from rubber like protein, elastin, snap fibers back into shape after stretching

22
Q

Reticular?

A

Made from short, fine collagen forming delicate networks, support soft tissue and blood vessels

23
Q

What are the resident cells of connective tissue proper?

A

Fibroblasts, fibrocytes, defense cells, adipocytes

24
Q

What are the resident cells of cartilage?

A

Chondroblasts, chondrocytes

25
Q

What are the resident cells of bone?

A

Osteoblasts, osteocytes

26
Q

What are the resident cells of blood?

A

erythrocytes, leukocytes, platelets

27
Q

What are the three types of fibers found in connective tissue?

A

collagen, reticular, elastic

28
