Membranes
Coverings around areas, mainly for protection
5 types of membranes

Union
Repair and healing of a wound in the skin
2 types of Union
Primary
Secondary
Primary
Regeneration of tissue
Secondary
Get some scar tissue in the place of original tissue
When would you use scar tissue?
Too deep
Too wide
Stays open
Steps to Union
Damage to tissue
Inflammatory response
Clot
Scab
New epithelial growth/regeneration under scab
Macrophages
Revascularization
Return to function
Clot
Blood stops and becomes C.T.
Scab
Dried out clot
Shrinks and pulls edges closer together
If too wide or too deep get scar tissue
Cancer tissue
Abnormal higher production of normal or abnormal cells
Where does cancer tissue usually occur
Labile tissues
Neoplasm
New growth tissue
Benign
Not spreading
Malignant
Spreading
Metastasis
Jumping, spreading to other tissues
Oncology
Study of cancerous tissue
