1) Loose CT
a) Areolar (surrounds all capillaries/vessels and underlies most epithelia)
i) Fibers
-Collagen (Type I)
-Reticular Fibers (Collagen Type III)
-Elastic Fibers
ii) Cell Types
-Fibroblast
-Macrophage
-Monocytes
-Plasma Cells
-Lymphocytes
-Mast Cells
-Eosinophils
-Neutrophils
-Adipose Cell
b) Adipose
i) Same Cell types as loose areolar CT.
ii) Brown and White
2) Dense CT
i) Regular
-Ligament, tendon
-Tension in one direction
-Only has fibroblasts
ii) Irregular
-Tension in more than one direction
-All of the cell types present in loose CT.
-Submucosa (intermediate layer between dense irregular and loose areolar CT in wall of digestive tube)
Parenchyma: Functional elements of an organ (i.e. gland cells)
Stroma: Supporting framework (i.e. connective tissue)
Mucous Membranes (mucosa):
-Moist Membranes that line every tubular/hollow organ that opens to the outside of the body i.e. digestive tract, respiratory passages, bladder
-Epithelial layer + loose CT (Lamina Propria)
Serous Membranes:
-Simple squamous epithelium (Mesothelium) + loose areolar CT
