1
Q

What are the 4 MAIN tissues types

A

Epithelial
Connective
Muscle
Nervous

2
Q

What are the special characteristics of epethial tissue

A
Polarity
Cellularity
Specialized contacts
Supported by connective tissue
Avascular
Regeneration
3
Q

Faces a free space (lumen or cavity); possesses apical and basal surfaces

A

Polarity

4
Q

Composed mostly of cells; tightly packed; no intracellular matrix

A

Cellularity

5
Q

Bound by special cell junctions and join cells in sheets

A

Specialized Contacts

6
Q

possesses a basement membrane composed of the basal lamina (secreted by epithelial cells) and reticular lamina (secreted by underlying connective tissue cells)

A

Supported by connective tissue

7
Q

no direct blood supply; cells depend on diffusion of nutrients usually from the connective tissue

A

Avascular

8
Q

high mitotic rate

A

Regeneration

9
Q

one cell layer thick

A

Simple cell arrangement

10
Q

two or more cell layers thick

A

Stratified Cell Arrangement

11
Q

all cells contact basement membrane but tissue appears stratified

A

Pseudostratified Arrangement

12
Q

specialized for stretching, smaller cells on top of large cells

A

Transitional Arrangement

13
Q

flat and scale-like

A

squamous cell shape

14
Q

height=width=length/depth

A

Cuboidal Cell Shape

15
Q

taller than wide

A

Columnar Cell Shape

16
Q

produces mucus which is propelled by cilia

A

Goblet Cell

17
Q

Dry Cutaneous Membrane

A

composed of dead surface cells filled with protein keratin that help form a barrier to water, microbes and abrasion

18
Q

Simple Squamous Epithelial Tissue

A

Locations: mesothelia (serosae), endothelia (lining of blood vessels, heart, lymphatic vessels), lung alveoli (air sacs), lining of Bowman’s capsule, and loop of Henle in kidneys
Functions: diffusion, filtration, secretion of serous fluid

19
Q

Simple Cuboidal Epithelial Tissue

A

Locations: lines of tubules of kidney, glands, and ducts
Functions: absorption and secretion

20
Q

Simple Columnar Epithelial Tissue

A

Locations: non-ciliated - lines gi tract from stomach to rectum and gall bladder
ciliated - lining small bronchi, uterine (fallopian) tubes, and some regions of the uterus
Functions: absorption and secretion

21
Q

Pseudostratified Columnar Epithelial Tissue

A

Locations: non-ciliated - lines sperm carrying ducts and ducts of large glands
ciliated - lines trachea and most of the upper respiratory tract
Function: secretion

22
Q

Stratified Squamos Epithelial Tissue

A

Locations: non-keratinized - lines moist surfaces (oral cavity, esophagus, vagina, and anus)
keratinized - dry surfaces (skin epidermis)
Function: protection

23
Q

Transitional Epithelial Tissue

A

Locations: lines ureters, bladder and part of the urethra
Function: distention/expansion/stretching
