chp 4 tissues/cancer

This is known as damage tissue is replaced by the same kind of tissue so original function is restored

what is regeneration

This is known as connective tissue replaces destroyed tissue and original function is lose

what is fibrosis

what are the 4 signs of inflammation

heat redness, swelling, pain

increase of permeability, histamine and chemicals reales, and vasodilation of blood vessels are examples of what

inflammation

this is formed under new developing epithelium tissue and is required before new tissue can be formed has fragile new capillaries

granulation tissue

thicked and fibroses tissue contracts, scab detached, epithelium is restored is in exmaple of what

regeneration

what are the four stages of tissue regeneration

inflammation, blood clotting, organization, regeneration

no regenerated cells include

cardiac tissue and nervous tissue

a hyperplasia tumor cells begin to change form being to look like immature cells with odd characteristics w/ abnormal behavior it is now know as what

dysplasia

growth and bigger size of dysplasia can still be benign

in situ cancer

cells are dividing more rapidly than normal knowon as a neoplasma

hyperplasia

slow growing localized encapsulated don’t kill host can be removed as a unit

benign tumor

faster growing non-encapsulated invaders adjacenct tissue and invaders blood stream and metastasizes other tissue

malignant tumor

oncogene is what

a gene that causes cancer that arise from mutations in normal genes or can inactive a tumor suppressor gene

cancer of epithelium cells

carcinoma

cancer of connective tissue or muscle

sarcoma

cancer of supporting cells

glioma

areolar ct blood, bone tissue, dense irregular ct, and epithelia tissues are all great at what

regenerating

what process produces scar tissue during tissue repair

fibrosis

what role do mast cells play

release inflammatory chemicals
