AppendicesAppendix A.A hernia is protrusion of an organ or the muscular wall of an organ througg the cavity that normally contains it. A hiatal hernia occurs when the stomach protrudes upward into the mediastinum through the esophageal opening in the diaphragm, and an inguinal hernia occurs when part of the intestine protrudes downward into the groin region and commonly into the scrotal sac in the male. A rectocele is the protrusion of a portion of the rectum toward the vagina through a weak part of the vaginal wall muscles. An omphalocele is a herniation of the intestines through the navel occurring in infants at birth. A cystocele occurs when part of the urinary bladder herniates through the vaginal wall due to weakened pelvic musclesAppendix B: AmniocentesisThe amnion is the sac that surrounds the embbryo in the uterus. Fluid accumulates within the sac and can be withdrawn for analysis between the 12th and 18th weeks of pregnancy. The fetus sheds cells into the fluid, and these cells are grown for microscopic analysis. A karyotype is made to analyze chromosomes, and the fluid can be examined for high levels of chemicals that indicate defects in the developing spinal cord and spinal column of the fetusAppendix C: PluralsWords ending in –us commonly form their plural by dropping the –us and adding –i. Thus, nucleus becomes nuclei and coccus becomes cocci. For additional information on formation of plurals, please refer to Appendix I, page 949, at the end of the book.Appendix D: Streptococcus and StaphylococcusStreptococcus, a berry-shaped bacterium, grows in twisted chains. One group of streptocoocci causes such conditions as “strep” throat, tonsillitis, rheumatic fever, and certain kidney ailments, whereas another group causes infections in teeth, in the sinuses of the nose and face, and in the valves of the heart.Staphylococci, other berry-shaped bacteria, grow in small clusters, like grapes. Staphylococcal lesions may be external or internal. An abscess is a collection of pus, white blood cells, and protein that is present at the site of infection.Examples of diplococci are pneumococci and gonococci. Pneumococci cause bacterial pneumonia, and gonococci invade the reproductive organs causing gonorrhea. Figure 3-3 illustrates the different growth patterns of streptococci, staphylococci, and diplococci.Appendix E: Blood CellsStudy Figure 3-4 as you read the following to note the differences among the three different types of cells in the blood.Erythrocytes. These cells are made in the bone marrow. They carry oxygen from the lungs through the blood to all body cells. The body cells use oxygen to burn food and release energy. Hemoglobin, an important protein in erythrocytes, carries the oxygen through the bloodstream. Leukocytes. There are five different leukocytes:Granulocytes contain dark-staining granules in their gytoplasm and have a multilobed nucleus. They are formed in the bone marrow and there are three types:1.Eosinophils are active and elevated in allergic conditions such as asthma. About 3 percent ofleukocytes are eosinophils2.Basophils. The function of basophils is not clear, but they play a role in inflammation. Lessthan 1 percent of leukocytes are basophils3.Neutrophils are important disease-fighting cells. They are phagocytes because they engulf anddigest bacteria. They are the most numerous disease-fighting “soldiers”, and are referred to as “polys” or polymorphonuclear leukocytes because of their multilobed nucleusMononuclear leukocytes have one large nucleus and only a few granules in their cytoplasm.They are produced in lymph nodes and the spleen. There are two types of mononuclear leukocytes4. Lymphocytes fight disease by producing antibodies and thus destroying foreign cells. Theymay also attach directly to foreign cells and destroy them. Two types of lymphocytes are T cells and B cells. About 32 percent of leukocytes are lymphocytes5. Monocyte: Engulf and destroy cellular debris after neutrophils have attacked foreign cells.Monocytes leave the bloodstream and enter tissues (such as lung and liver) to become macrophages, which are large phagocytes. Monocytes make up about 4 percent of all leukocytes.Appendix F: Pronunciation CluePronunciation clue: The letters g and c are soft when followed by an i or e, and are hard when followed by an o or aAppendix G: AnemiaAnemia literally means no blood. However, in medical language and usage, anemia is a condition of reduction in the number of erythrocytes or amount of hemoglobin in circulating blood. Anemias are classified according to the different problems that arise with red blood cells. Aplastic (a = no, plas/o = formation) anemia, a severe type, occurs when bone marrow fails to produce not only erythrocytes but leukocytes and thrombocytes as well.Appendix H: IschemiaIschemia litterally mens to hold back (isch/o) blood (-emia) from a part of the body. Tissue that becomes ischemic loses its normal flow of blood and becomes deprived of oxygen. The ischemia can be caused by mechanical injury to a blood vessel, by blood clots lodging in a vessel, or by the progressive and gradual closing off (occusion) of a vessel caused by collection of faty material. Appendix I: TonsillitisThe tonsils are lymphatic tissue in back of the throat. They contain white blood cells (lymphocytes), which filter and fight bacteria. However, tonsils can also become infected and inflamed. Streptococcal infection of the throat causes tonsillitis, which may require tonsillectomy.Appendix J: AcromegalyAcromegaly is an endocrine disorder. It occurs when the pituitary gland, attached to the base of the brain, produces an excesive amount of growth hormone after the completion of puberty. The excess grouth hormone most often results from benign tumor of the pituitary gland. A person with acromegaly is of normalheight beccause the long bones have stopped growth after puberty, but bones and soft tissue in the hands, feet, and facegrow abnormally. High levels of growth hormone before completion of puberty produce excessive growth of long bones (gigantism) as well as acromegaly.Appendix K: SplenomegalyThe speen is an organ in the left upper quadrant (LUQ) of the abdomen (below the diaphragm and to the side of the stomach). Composed of lymph lymph tissue and blood vessels, it disposes of dying red blood cells and manugactures white blood cells (lymphocytes) to fight disease. If the speen is removed (dplenectomy), other organs carry out these functions.Appendix L: LeukocytosisWhen –osis is a suffix with blood cells, it is an abnormal condition of increase normal circulating blood cells. Thus, in leukocytosis an elevation in numbers of normal white blood cells occurs in response to the presence of infection. When –emia is a suffix with blood cells, the condition is an abnormally high, excessive increase in number of cancerous blood cells.Appendix M: AchondroplasiaAchondroplasia is an inherited disorder in which the bones of the arms and legs fail to grow to normal size because of a defect in both cartilage and bone. It results in a type of dwarfism characterized by short limbs, a normal-sized head and body, and normal intelligence.Appendix N: -ptosis = blepharoptosisThe suffix –ptosis is pronounced. When two consonants begin a word, the first is silent. If the two consonants are found in the middle of a word, both are pronounced for example, blepharoptosis. This condition occurs when eyelid muscles weaken, and a person has difficulty lifting the eyelid to keep it open.Appendix O: Laparoscopy = peritoneoscopy = MIS, mingmally invasive surgeryLaparoscopy is visual examination of the abdominal cavity using a laparoscope. The laparoscope, a lighted telescopic instrument, is inserted through an incision in the abdomen near the navel, and gas is infused into the peritoneal cavity to prevent injury to abdominal structures during surgery. Surgeons use laparosocopy to examine abdominal viscera for evidence of disease or for procedures such as removal of the appendix, gallbladder, adrenal gland, spleen, or colon, and repair of hernias. It is also used to clip and collapse the fallopain tube, which prevents sperm cells from reaching eggs that leave the ovary.Appendix P: Arteriole, capillary, venuleNotice the relationship among an artery, arterioles, capillaries, venules, and a vein as illustrated in Figure 3-8Appendix Q: AdenoidsThe adenoids are lymphatic tissue in the part of the pharynx (throat) near the nose and nasal passages. The literal meaning “resembling glands”is appropriate because they are neither endocrine nor exocrine glands. Enlargement of adenoids may cause blockage of the airway from the nose to the pharynx, and adenoidectomy may be advised. The tonsils are also lymphatic tissue, and their location as well as that of the adenoids is indicated in Figure 3-9.V.
