| Introduction to Primary Hemostasis Primary hemostasis is considered the starting point for the hemostatic response mounted by the body, subsequent to vascular damage. Its activation serves as a trigger for ensuing hemostatic processes, as the mechanisms are all interrelated. Primary hemostasis consists of two key parts: The vascular system Platelets (thrombocytes) | View Page |
| Thrombocytes (Platelets) The third group of formed elements in normal peripheral blood is made up of thrombocytes (platelets). Although platelets don't look very impressive, their role in the process of hemostasis is critical. Platelets are the small granular bodies shown with the arrows in this Wright stained smear. | View Page |
| Glossary of Terms N through Z. N:C Ratio - Nuclear: cytoplasmic Ratio - The ratio of nuclear volume to cytoplasmic volume within any one cell.Neoplasm - Any new and abnormal growth, such as a tumor.Neutrophilic Granules - Specific granules present in the cytoplasm of neutrophils. These granules resemble pencil stippling and stain a lilac color due to their affinity for both basic and acid dyes.Phagocyte - Any cell that ingests microorganisms or other cells and foreign particles.Phagocytosis - The ingestion and destruction of microorganisms or other foreign particles.Plasma - The fluid portion of blood in which the various blood cells are suspended.PF3 (platelet Factor 3) - A lipoprotein component of the platelet membrane; functions as a surface catalyst during blood coagulation.Pseudopod - A temporary protrusion of the cytoplasm of a cell.Refractile - Capable of refracting or changing the direction of light.Senescence - The process or condition of growing old.Serotonin - A constituent of blood platelets and other cells and organs; induces constriction of the blood vessels.Specific Granules - Granules found in cells of the more mature stages of the granulocytic series. They have distinct staining reactions which differ with each type of granulocyte.T-cell - Thymus derived lymphocyte which mediates cellular immunity.Thrombocyte (Platelet) - A circular or oval disk found in the blood; concerned with hemostasis.Thymus - A ductless gland-like body situated in the anterior mediastinal cavity; reaches its maximum development during the early years of childhood.Vacuole - Any small space or cavity formed in the cytotoplasm of a cell. | View Page |
