NRSG 2350 Pathopharmacology Module 1 | UPDATED
Questions with 100% Verified Answers
Q1: Chemical Makeup of Cell Membrane
A: Lipoproteins, receptor sites, identifying markers, channels
Q2: Lipoproteins
A: Biphospholipid bilayer - lipids inside and proteins outside the cell
Q3: Receptor sites
A: Proteins that interact with chemicals outside the cell to trigger reactions or changes
Q4: Identifying Markers
A: Surface antigens, help in communication and identifications
Q5: Function of Cell Membrane
A: Homeostasis, passive and active transport
Q6: Homeostasis
A: Maintain stability in the system and cell
Q7: Negative Feedback
A: A primary mechanism of homeostasis, corrects or cancels responses when there is too
much of something
Ex.) Temp., glucose
Q8: Positive Feedback
A: Feedback that tends to magnify a process or increase its output
Ex.) Childbirth, sneezing, blood clots
Q9: Osmosis
A: Movement of water, high solutes = high osmotic pressure
Q10: Osmotic Pressure
A: Pressure that must be applied to prevent osmotic movement across a selectively
permeable membrane
Q11: Atrophy
A: Cells waste away, become small in size, not being used
, Q12: Hypertrophy
A: Increase cell size due to overuse
Q13: Hyperplasia
A: Increase in number of cells
Q14: Dysplasia
A: Abnormal version of the same cell, can lead to disease, often irreversible
Q15: Metaplasia
A: One cell replaced with another, reversible
Q16: Apoptosis
A: Normal, shrink, controlled cell death, allows for new cell growth
Q17: Ischemia
A: Lack of oxygen and or blood supply to cells/organs
Q18: Necrosis
A: Cell death by loss of oxygen and or blood supply, irreversible
Q19: Etiology
A: Cause
Q20: Predisposing Factors
A: Risk factors
Q21: Pathogenesis
A: Development of disease
Q22: Insidious
A: Vague onset within symptoms, we don't see it coming
Q23: Intrinsic Causes of Illness and Disease
A: Genetics, age, gender
Ex.) Sickle Cell Anemia and Cystic Fibrosis
Q24: Extrinsic Causes of Illness and Disease
A: Infectious, alcohol and drug use, diet, inactivity, smoking, stressors, and environmental
exposures
