Disorders: musculoskeletal, digestive, cardiovascular, neurolotical

Esophageal atresia (congenital) a developmental factor which the upper & lower esophageal segments (LES) are separated; the upper section ends in a blind pouch; usually a connecting fistual from one segment to trachea
Congenital pyloric stenosis may be developmental in infants, or acquired later in life, usually b/c of fibrous scar tissue; the pyloric muscle is hypertrophied & can be palpated as a hard mass in the abd.
Chronic gastritis "inflammation in the stomach"; atrophy of the mucosa of stomach, w/loss of secretory glands; seen in indviduals w/PUD, alcohol abuse, and aging; Also Autoimmune disorders are associated; loss of parietal cells leads to achlorhydria & lack of Vit B-12
Oral candidiasis a common fungal infection that occurs in people who have taken broad spectrum atibiotics, cancer chemotherapy, or glucocorticoids & in those who have diabetes or are immunosuppressed; may appear as red, swollen and white curdlike material on mucosa
Alzheimer's disease common form of demetia' changes in progressive cortical atrophy, which leads to dilated ventricles * widening of sulci, particularily in parietal & frontal lobes; deficit of ACh occurs
Huntinton's disease an inherited disorder that does not manifest until midlife: maternal inheritance delays onset longer than inheritance from fathers. Progressive atrophy of the brain occurs. w/degeneration of neurons: depletion of GABA, ACh
Amyotrphic laterl sclerosis "Lou Gehrig's disease" amyotrophic=muscle wasying,; sclerosis=degenerative hardening of lateral corticospinal tracts; affects upper motor neurons in cerebral cortex & lower motor neurons in brainstem & spinal cord. s/s spastic paralysis, hyperreflexia,
Parkinsons' disease dysfuntion of extrapyramidal motor system occurs b/c or pregressive degenerative changes in basla nuclei; decreased # of neurons secrete dopamine leading to an imbalance b/t excitation & inhibition of basal nuclei: s/s tremors, facial/ocular
Peptic Ulcer Disease "PUD" occurs primarily proximal deodenum, also stomach antrum and lower esophagus; usually appears as cavity penetrating sub-mucosa. Ulcers can penetrate and perforate mucosal wall.
Ulcerative colitis inflammation commences in the rectum & progresses thru colon.; Inflammed Mucosa becomes edematous/friable and ulcerations develops. Vascular granulation tissue forms and easily bleeds; large coalesce areas become denuded.
Cirrhosis of the liver a condition demonstrating extensive diffuse fibrosis loss of lobular organization; regenerated hepatocyte nodules may be present; progressive disorder leading to liver failure; Pathophysiologic effects evolve loss of liver cell functions
Thrombus formation may form spontaneously usually b/c of stasis of blood or increased coagulabitlity of blood, or clot may from over an inflamed vein; Common in legs or pelvis. Piece of thrombus may break aways, an embolus to the heart of lungs (PE).
Hepatitis Infection from a group of viruses that target the hepatocytes: these include: hepatitis A (HAV ), HBV, HCV, HDV, & HEV. Liver cells are damaged by direct action of the virus or by cell-mediated immune responses to the virus. Liver necrosis results
Acute pancreatitis Inflammation of pancreas resulting from autodigestion of tissues; acute or chronic; autodigestion follow premature activiation of pancreatic proenzymes w/in the pancreas; (trypsin, proteases amylase & lipase); Massive Inflammation process
Esophageal varices caused from being connected w/gastric veins & cirrhosis of the liver increasing the pressure of blood that extends into the esophageal veins, creating large distended & distorted veins near the mucosal surface of the esophagus; Complication hemorrhage
Crohn's disease affects digestive tract, frequently small intestines. inflammation occurs (skip lesions) with affected segments clearly separated by normal tissue. Mucosal inflammation leads to ulcers that tend to coalesce to form fissures; Obstucts intrinsic factor
Multiple sclerosis progressive neuron demyelination (brain, spinal cord, & cranial nerves) affects all types of nerves throughout NS; MS is marged by remission/exacerbation until neural degeneration is irreversible
Duchenne's muscular dystrophy `X-linked recessive (only males); a metabolic defect, a deficit of dystrophin, a muscle cell membrane protein, leads to degeneration/necrosis of cell; skeletal muscle fiberas are replaced by fat/fibrous connective tissue; muscle funtions is lost
Ankylosing spondylitis vertebral joints first become inflamed; fibrosis, calcificatin or fusion of joints follow; the result is ankylosis or fixation of the joints. Inflammtion begins in the lower back (sacrial joint) progresses up the spince, causing a "poker back"
Rheumatoid arthritis autoimmune disorder causing chronic systemic inflammaroty disease; remissions/exacerbations lead to progressive joint damage. Rheumatoid factor (RF) is an antibody against I-Gh that is present in blood. Mobility is impaired
Gout common in men (> 40 yo) joint disease; results from deposits of uric acid (waste) & urate crystals in the joint developing acute inflammatory response. Gout affects a single joint; articular cartilage is damaged;
Cholelithiasis the formation of gallstones (solid masses/calculi bile formation); Larger stones obstruct bile flow causing pain; inflammation /infection in the biliary may provide exaccerbate stone formation.
Osteocytes mature bone cells (osteoblasts) tha lie b/t rings of matrix in spaces called lacunae.
Osteoblasts new bone forming cells
Osteoclasts reabsorbs & removes old & damaged bone cells
Stem cells a basic cell that may divide to give rise to a variety of specialized cells.
Hepatits A (infectious) affects kids & young adults through fecal-oral & sexual contact (contamiated water & homosexual partners). Incubation pd of 2-6 wks.
Hepatitis B (serum) insidious onsetl thr blood & sexual contact that worsens w/age: double-stranded DNA virus; has 3 antigens; incubation pd or 2 months
Hepatits C (non-A, non-B) insidious onset in adults thru blood & parenteral routes; most common from blood transfusions; single stranded RNA virus; incuation pd of 2 wks-6 mths (usually 9 wks)
Heptitis E acute fecal-oral route: may be sever; single stranded RNA virus; similar to type A; common in Africa & Asia w/high mortality rate in pregnat women; incubation pd is 2-9 wks.
Toxic Hepatits direct exposure; incubation days to months; can be acute or chronic; caused by hepatotoxins
Hepatitis Chronic non-infectious autoimmune; idiopathic; chronic; unknown incubation pd.
Baroreceptors pressure-sensitive nerve endings tha detect changes in blood pressure & alerts cardiac system. Located inwalls or aortic arch, atria of hearts, and carotid sinuses.
Cardia preload the stretch of ventricular muscle fiber @ the end of diastole; Cardiac output increases; reflected by ventricular pressure & volume @ the part of the cardiace cycle.
Glycogenosis the synthesis of glycogen from glucose
Achalasia abnormal condiditon characterized by inability of a muscle to relax. particularly the LES
Myelomeningocele developmental defect of CNS in which hernial sac containing a porton of spinal cord, its meninges, & cerebrospinal fluid protures thru a congenital cleft in the vertebral column; caused by failure of neural tube to close during embryonic development
