1
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
Are there blood vessels and/or extracellular materials (ECM) in epithelial tissue?
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
What are the 5 classifications of CT?
-fibrous
-adipose
-cartilage
-bone
-fluid
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.
