BIO044 (LAB) MOD 2 ANIMAL TISSUE Flashcards
Is a group of cell that have a similar function or specialization with an organism.
Tissue
The origin tissues will on which __________ the cells originated
Germ layer
4 types of animal tissue
- EPITHELIAL TISSUE
- CONNECTIVE TISSUE
- MUSCLE TISSUE
- NERVOUS TISSUE
This tissue forms the protective covering and inner linings of the body and organs.
EPITHELIAL TISSUE
They develop from the ectoderm, endoderm, and mesoderm.
EPITHELIAL TISSUE
The tissue is made of tightly packed cells supported by and underlying__________.
Basement membrane
Different types of epithelial tissue are identified according to:
- Shape of the epithelial cell
- Number of cell Layers
Shape of the epithelial cell:
- Squamous
- Cuboidal
- Columnar
Number of cell Layers:
- Simple
- Stratified
Flat, polyhedral cells with a nucleus at the center
Squamous
Cells with almost equal height from width with a nuclear at the center.
Cuboidal
Cells which are taller than wide with a nucleus at the region.
Columnar
Cells are only in one layer.
Simple
Cells are stacked in more than one layer.
Stratified
Cells appear to have more than once layer, but actually is just one layer with different sized cells overlapping each other.
Pseudostratified
“pseudo” means =
Fake
The epithelial tissue is made of a single layer of flat cells.
Simple squamous epithelium
This tissue supports and bind other organs and tissues together, preventing organs form mechanical shocks, also helps repair other tissues.
CONNECTIVE TISSUE
Connective tissue develop from the_______.
Mesoderm
