CT Flashcards
General CT
Loosely, vascular, support and connect, nerves and lymph
Origin CT
Mesoderm
Tissue proper components
Fibers
Ground/matrix
Cells
Ground CT
Transfer bet cells and blood and cell interactions
GAGs»_space; heparin+keratin+ hylaraunic( surrounds ova)
Glycoproteins»chondronectin(cartilage(

Fibers types, branching
White collagen» branched bundle, single not branched
Yellow elastic» branched fiber
Reticular» branched thin fibers
White is.. made from…
Tough to resist with alternating dark and light segments (axial periodicity)
3 a polypeptide chains> tropocollagen>collagen fibril> collagen fiber
Yellow is
Stretchable, made of elastin protein between fibers there is cross links
Reticular is..
Very thin, type 3 collagen
Collagen types
1 bone, skin, cartilage spine(white fibrocartilage)
2 hyaline, elastic cartilage (trachea)
3 reticular (spleen and lymph)
4 basement membrane
CT stem cell
Mesenchymal cell
Attaches to blood capillaries and become pericyte ( rise in CT cells in blood)
5 cells list them CT
Fibrocyte
Fat
Plasma
Macrophage
Mast cell
Fibroblast
Vesicular nucleus, fibers and matrix, synthesis and secretion, healing after injury
Fibrocyte( mature and non dividing)
Fat
White, signet ring, unilocular, subcutaneous tissue heat insulation and energy storage
Brown, multilocular, around aorta, gives energy for babies, many mitochondria
Plasma cell
Clock Face appearance, from activated b-lymphocyte, produces immuno globins
Macrophage
Phagocytosis
Monocyte in blood
APC
Antigen presenting cell
Macrophage
Mast cell
Histamine and heparine
Basophilic granules
Allergy and hypersensitivity
Clinical CT
Foam cells» macrophages in lipid tissue in blood, eats lipids and die filled with them, narrowing the blood vessel
Atherosclerosis
Lipoma»benign tumor from fat tissue
Soft, movable, painless, under the skin, non cancerous
Surgical removal
Males»
Brown adipose is rich in
Blood capillaries
Dense regular ct vs dense irregular
Tendon
Skin
Yellow elastic
Lung/aorta
