Common Functions of Epithelia?
Physical Protection, Selective Permeability, Absorption of Epithelial Lining, Secretion and Release, and Reception of Sensations.
- Single Layer of Thin, Flat Cells

Stratified Columnar Epithelium.
What Are Glands?
Individual Cells and Multicellular Organs of Epithelial Tissue.
What Are Endocrine Glands?
Lacks Ducts and Secretes Products (I.E. Hormones) Into Blood Transported Body.
What Are Exocrine Glands?
Unicellular, Contains No Ducts, Numerous Cells Work Together to Produce Secretion.
What Are Exocrine Glands’ Functions?
Development, Imagination of Epithelial Burrogous Underlying Connective Tissue.
- Merocrine: Package Secretion in Secretory Vesicles Through Exocytosis
- Aprocrine: Secretory Material Cell’s Apical Portion Pincthes Off Through Endocytosis
- Holocrine: Cells accumulate a Product - the Entire Cell disintegrates (Dead Cell Epithelial Contains Cell Division)
The Classification of Exocrine Glands.
What are Fibroblasts?
They Produce the Protein Fibers and Ground substance components of the Extracellular Matrix.
What Are Adipocytes?
Small Clusters of Connective Tissue Proper, Large Clusters Dominate an Area, and Related to Adipose Connective Tissue.
What Are Mesenchymal?
Embryonic Stem Cell within Connective Tissue. Cells will divide if Tissue is damaged, and differentiate into The Type of Connective Tissue it is needed.
