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.
