Spleen Flashcards
Ligament between the spleen and the splenic flexure of the colon
Phrenocolic ligament
Within the peritoneal cavity
Intraperitoneal
Complete absence of the spleen
Splenic Agenesis
Condition when there is more than one spleen
Polysplenia
Results from the failure of fusion of the separate splenic masses forming on the dorsal mesogastrium; most commonly found in the splenic hilum or along the splenic vessels or associated ligaments
Accessory Spleen
Leaves the splenic hilum, travels transversely through the supper abdomen to join w/ the SMV to form the main portal vein; serves as the posterior medial border the pancreas
Splenic Vein
Located in the middle of the spleen; site where vessels and lymph nodes enter and exit the spleen
Splenic Hilum
Spleen that has migrated from its normal location in the LUQ
Wandering Spleen
One of the ligaments between the stomach and spleen that helps hold the spleen in place
Gastrosplenic Ligament
Alkaline fluid found around the lymphatic vessels
Lymph
Ligament between the spleen and the kidney that helps support the greater curvature of the stomach
Lienorenal Ligament
Certain Phagocytic cells (found in liver and spleen) make up the reticuloendothelial system (RES); plays a role in synthesis of blood proteins and hematopoiesis
Reticuloendothelial
LUQ of the abdomen that contains the left lobe of the liver, spleen, and stomach
Left Hypochondrium
Branch of the celiac axis; toruous course towards the spleen; serves as a superior border of the pancreas
Splenic Artery
Follicles in the white pulp of the spleen, containing many lymphocytes
Malpighian Corpuscles
Pigment released from hemoglobin process
Hemosiderin
Blood cell production
Hematopoiesis
Defends the body by destroying invading microorganisms and their toxins
White Blood Cells (WBC)
Consists of reticular cells and fibers; surrounds the splenic sinuses
Red Pulp
Red blood cell
Erythrocyte
Abnormal decrease of white blood corpuscles; may be drug induced
Leukopenia
Consists of lymphatic tissue and lympathic follicles
White Pulp
Process by which the spleen removes nuclei from bllod cells without destroying the WBC
Pitting
Process by which the spleen removes abnormal red blood cells as they pass through
Culling
Oxygen-binding protein found in red blood cells
Hemoglobin
Long irregular channels lined by endothelial cells or flattened reticular cells
Splenic Sinuses
Process by which the red pulp destroys the degenerating red blood cells
Phagocytosis
Metabolic disorder marked by amyloid deposits in organs and tissue
Amyloidosis
Anemia caused by antibodies produced by the patient’s own immune system
Autoimmune Hemolytic Anemia
One of the storage diseases in which fat and proteins are deposited abnormally in the body
Gaucher’s disease
Anemia caused by hemolysis of red blood cells
Hemolytic anemia
Malignant disease that involves the lymphoid tissue
Hodgkin disease
Interruption of the blood supply to an area that may lead to necrosis of the area
Infarction
acute infection caused by the Epstein-Barr virus that most commonly affects teenagers and young adults; symptoms include fever, sore throat, enlarged lymph nodes, lymphocysts, and hepatosplenomegaly
Mononucleosis
Malignant disease of lymphoid tissue seen in increased frequency in individuals more than 50 years of age
non-Hodgkin lymphoma
Excess of red blood cells
Polycythemia
Inherited disorder transmitted as an autosomal recessive trait that causes an abnormality of the globin genes in hemoglobin
Sickle-cell Anemia
Condition in sickle cell anemia in which the sickled cells interfere w/ oxygen transport, obstruction capillary blood flow and cause fever and pain in joints and abdomen
Sickle-cell Crisis
Group of hereditary anemias occuring in Asian and Mediterranean population
Thalassemia
Enlargement of the spleen
Splenomegaly
Hereditary condition in which the erythrocytes assume a spheroid shape
Spherocytosis
Chronic life-shortening condition of unknown cause involving bone marrow elements; characterized by increase in red blood cell mass and hemoglobin concentration
Polycythemia Vera
