Functions of Epithelial Tissue
-Protection
-Excretion
-filtration
-secretion
-absorbtion
Simple Epithelium (3)
-Absorbtion
-Secretion
-Diffusion
Pseudostratified epithelium
Still simple epithelium because all cells rest on basement membrane
Stratified epithelium
2 or more layers of cells used for protection
Squamous Cells
Flat and thin for rapid passage
Cuboidal Cells
Shaped like cubes for secretion or absorbtion
Columnar Cells
Columns for secretion and Absorbtion
Transitional cells
Changes shape between cuboidal to squamous
Endothelium
Simple Squamous that lines Hear, Blood and lymph vessels
Mesothelium
Simple squamous that forms Peritoneum
Goblet Cells
Modified Columnar cells that secrete mucus for protection or lubrication
Keratin

Acinar Gland
Glands shaped more fat and rounded
TubuloAcinar Gland
Has both Tubular and Acinar Glands
Merocrine Glands
Secretions are synthesized on ribosomes on Rough ER, packed by Golgi, and secreted via vesicles

i.e Salivary Gland
Apocrine Glands
Accumulates secretory product at surface and that portion of cell pinches off.
i.e Mammary Glands

*Electron micrographs calls into question the existance of these glands
Holocrine Glands
Cell explodes and releases the products

i.e Sebaceous Gland
-blast
Signifies an immature cell still capable of much division
-cyte
signifies a mature cell no longer able to divide very often
Fibroblasts
A Connective Tissue cell that Floats around and secretes gound substance of the Extracellular Matrix
Macrophages
Large Eaters floating around connective tissue to eat stuff
Plasma Cells
A Connective Tissue cell that secretes antibodies
Mast Cells
A Connective Tissue cell taht produce histamine to dilate small blood vessels as an inflammatory response
Adipocytes
Fat Cells that store triglycerides (Fats)
White Blood Cells
A cell that migrates from blood to connective tissue to fight
Ground substance
Component of connective tissue between cells and fibers
GAGs
Stuff that makes up ground substance
Collagen Fibers
Can be bent but cannot stretch
Elastic Fibers
Can be stretched very long and return to original shape
Reticular Fiber
Like Collagen Fibers, Can bend but not stretch
Mesenchyme
Example of embryonice connective tissue that all other connective tissues arise from
Types of Loose Connective Tissue
(3)
-Areolar
-Adipose Tissue
-Reticular
Areolar Connective Tissue (2)
