What are the 3 embryonic tissues?

1. ectoderm (outer)
2. mesoderm
3. endoderm (inner)

2

Where do u find epithelial tissue?

-covers body surface,
-lines body cavities,
-forms external and internal linings of many organs, mostly glandular tissue

3

no blood vessels
very little ECM

4

What are the two broad categories with epithelial tissue?

simple and stratified

5

What are the 4 types of epithelia in each category names for shapes of cells?

-squamous
-cuboidal
-columnar
-pseudostratified (or other)

6

What is connective tisssue (CT) made of?

mostly matrix= GS and fibers with widely separated cells

7

-fibrous
-adipose
-cartilage
-bone

8

What are the functions of CT? give an example.

-Bind organs. ex. tendons bind muscle to bone
-Support. ex. bones support the body
-Immune protection. ex. CT cells attack foreign invaders
-Movement. ex. bones provide lever system for body movement.
-Storage. ex. fat is energy reserve, bone reservoir of Ca+ and PO4^3-.
-Transport. ex. blood transports gases, nutrients, wastes, etc.
