Advanced Patho Usf Exam Questions (228 Terms) With Verified Definitions Updated 2024

Transient Ischemic Attack (TIA) {Ans: - Brief neuro dysfunction from ischemia (penumbra) without infarction - Neuro deficits last from hours to no more than 24 hours-actually usually resolve within one hour of symptom onset. - PPL w/ hx of TIAs 9xmore likely to have a stroke-resulting in more aggressive tx by HCP of TIAs - No actual infarct or cell death because blockage does not last long enough for cell death to occur}Nervous System Cells: ASTROCYTES {Ans: - Maintains intracellular environment by controlling nutrients and waste - Maintain the blood-brain barrier - Brain tissue repair/scarring}Forms of Adaptation: HYPERPLASIA {Ans: - An increase in the number of cells in an organ or tissue - Can be physiologic (wound repair) or pathologic (usually from excess hormonal stimulation, e.g., BPH) - Hormonal (as in breast enlargement w/ pregnancy) - Compensatory (regeneration of an organ after partial removal, collateral circulation around occluded artery) - Non-mitotic cells (e.g., neurons) are almost never hyper plastic}Rotator Cuff {Ans: - 3 bones Scapula, clavicle, humerus - 3 joints Acromioclavucular Glenohumeral sternoclavicular - 4 muscles - Unstable due to shallowness of the glenohumoral joint}Neurotransmitters: ACETYLCHOLINE {Ans: - Stimulation of muscles (skeletal, GI) sensory neurons,
