Tissue
|
similar cells that perform common function.
|
|
|
Matrix
|
nonliving material between the cells.
|
|
|
Intercellular
|
between cells
|
|
|
Intracellular

within cells
|
|
|
4 types of tissues
|
Epithelial- covers/protects body
Connective- supports and connects body parts Muscle- produces movement Nervous- most complex/ communication/ coordination |
|
|
Three primary germ layers
|
Endoderm- epithelial tissues
Mesoderm- connective and muscle Ectoderm- nerve tissue |
|
|
Histogenesis
|
process of germ layers differentiating into different kinds of tissue.
|
|
|
Two groups of Epithelial Tissue
|
Membranous- covers body/ resp., digest, genitourinary tracts
Glandular- solid cords of endocrine and exocrine glands. |
|
|
Functions of Epithelial tissues
|
Protection
Sensory Secretion Absorption- intestines/resp. Excretion- kidneys |
|
|
Avascular
|
do not contain blood vessels or without vessels.
|
|
|
4 membranous epithelial cell shapes
|
squamous- flat and platelike
Cubodial- cube shaped Columnar- narrow and cylindrical Pseudostratified columnar- one layer of oddly shaped columnar cells |

|
|
3 layers of cells
|
Simple- single layer
Stratified- layered one on top of another Transitional- differ cells shapes in stratified or layered sheet. |
|
|
Simple Squamous epithelium
|
one cell layer of lfat, scale like cells, permeable to substances.
