Cutaneous Membrane
"Skin." Stratified squamous epithelium layer (epidermis) firmly attached to a thick layer of dense irregular connective tissue (dermis). Dry membrane that is exposed to the air.
Mucous Membranes/Mucosae
Membranes that line body cavities which are open to the exterior, such as those of the hollow organs of the digestive, respiratory, and urogenital tracts. While all are "wet" membranes, not all secrete mucus.

Contains either stratified squamous or simple columnar epithelia.
Serous Membranes/Serosae
Moist membranes found in closed ventral body cavities. Secrete lubricating serous fluid.

Named according to their site and specific organ associations.
Serosal membrane lining a cavity.
Serosal membrane covering an organ.
Serosal membrane lining the thoracic wall and covering the lungs.
Serosal membrane lining the pericardial cavity and covering the heart.
Serosal membrane lining the abdominopelvic cavity and covering the viscera.
Steps of Tissue Repair
1. Inflammation
2. Organization
3. Regeneration and fibrosis
Replacement of destroyed tissue with the same kind of tissue.
Proliferation of fibrous connective tissue called scar tissue to replace destroyed tissue.
-Tissue trauma causes injured cells to release inflammatory chemicals which cause the capillaries to dilate and become very permeable.
-WBC's and plasma fluid rich in clotting proteins/antibodies/etc. seep into injured area
-Clotting proteins construct a clot
-Clot exposed to air forms a scab
-blood clot is replaced by granulation tissue
-proliferating fibroblasts produce growth factors and collagen fibres to bridge the gap
-fibroblasts contract and pull margins of wound together
Granulation Tissue
Tissue containing capillaries that grow in from nearby areas and lay down a new capillary bed during organization. Also contains fibroblasts.
-Surface epithelium regenerates, growing under the scab, which soon detaches.
-As fibrous tissue beneath matures and contracts, regenerating epithelium thickens until it resembles that of the adjacent skin.
Highly regenerative tissues (name)
epithelial, bone, areolar connective tissue, dense irregular connective tissue, blood-forming tissue
Moderately regenerative tissues (name)
Smooth muscle, dense regular connective tissue
Weakly regenerative tissues (name)
skeletal muscle, cartilage
Tissues with no functional regenerative capacity (name)
Cardiac muscle, nervous tissue of brain/spinal cord
Precursors of connective tissues
Precursors of cartilage
Precursors of osseous tissue (bone)
Hematopoietic Stem Cell/Blood Cells and Macrophages
Precursors of blood tissue.
