Anatomy Flashcards
Life Span of RBC
120 days
Poikilocytosis
Varying shapes of RBCs
Anisocytosis
Varying sizes of RBCs
Erythrocytosis
polycythemia, increased hematocrit
Platelet dense granules
ADP, Calcium, ATP, 5-HT, histamine
platelet adhesion and vasocontriction
Platelet alpha granules
vWF, fibrinogen, plasminogen, PDGF
platelet derived GF
Life Span of Platelets
8-10days
Leukocyte WBC differential from highest to lowest
Neutrophils (54-62%) Lymphocytes (25-33%) Monocytes (3-7%) Eosinophils (1-3%) Basophils (0-0.75%)
Multilobed Nucleus, Phagocytic, acute inflammatory response
Neutrophil
Defensins
Neutrophil cationic protein
Hypersegmented Neutrophil
5 or more lobes, seen in Vitamin B12/folate deficiency
Increased Band cells
Immature neutrophils reflecting states of increased myeloid proliferation (bacterial infections, CML)
Reticulocyte
immature erythrocytes, marker of erythroid proliferation
Differentiates into macrophages, large, kidney-shaped nucleus. Extensive “frosted glass” cytoplasm
Monocyte
Monocytes that migrate into tissue
Histocytes
Monocyte life in blood
3 days
CD14
cell surface marker for macrophage
Important component of granuloma formation
Macrophage
Bilobate Nucleus
Eosinophil
Crystalloid Body
Eosinophil, major basic protein
Helps limit reaction following mast cells degranulation
Eosinophils’ histaminase and arylsulfatase
Causes of Eosinophilia
Neoplasia, Asthma, Allergic Processes, Connective Tissue Diseases, Parasites
Neutralizes SRS-A of anaphylaxis
Arylsulfatase (from eosinophils)
Mediates Allergic Rxn, contain heparin (anticoagulant), histamine(vasodilate), and leukotrienes
Basophils
Bilobed nucleus that is obscured with granules
Basophils
has FcR for IgE to trigger release
Basophils
Isolated basophilia
CML
Cell involved in type I HS
Mast Cells
Cromolyn
prevents mast cell degranulation (used for asthma prophylaxis)
IgE cross-links upon Ag binding causing degranulation releasing histamine, heparin and eosinohpil chemotactic factors
Mast Cells
Highly phagocytic APC, functinos as a link between innate and adaptive immune system
Dendritic Cell
Dendritic cell in the skin
Langerhands cell
Round, densely staining nucleus with small amount of pale cytoplasm
Lymphocytes
Express CD19, CD20
B-lymphocyte
All T-cells express
CD2, CD3, CD7
Primary target for HIV
CD4+T helper cells
Co-stimulatory signal necessary for T-cell activation
CD28
Clock-face chromatin distribution
Plasma Cell
Kills virus infected and tumor cells
NK Cells
express CD56
NK Cels
Who is fucking tired?
