Cell membrane composed of Ansphospholipids, cholesterol, glycolipid Role of phospholipids Ansrepairing the cell by folding Cell membrane is highly permeable to AnsCO2, O2, fatty acids, steroid hormones Resting membrane potential Ansslight difference in charge between ICF and ECF. Charge is -70 to -85mV Action potential Anssudden impulse and rapid change in resting membrane potential.

Seven specialized cellular functions: Ansmovement, conductivity, metabolic absorption, secretion, excretion, respiration, and reproduction Nucleus Ansaids in cell division and control of genetic info, contains DNA (think the egg yolk) Ribosomes AnsRNA-protein complexes; float freely in cytoplasm; provide sites for cellular protein synthesis; packages and modifies protein for transportation and secretion Endoplasmic Reticulum (ER) Ansspecializes in the synthesis and trans...

Mitral Valve Stenosis Ans- Characterized by NARROWING of mitral valve - Normal is 4-6 cm -Narrowed is less than 2.5 cm - Caused by RHEUMATIC FEVER -More common in WOMEN -Oxygenated blood comes back into heart into the left atrium and down through the mitral valve to the left ventricle - Complex: Stenosis leads to volume/pressure in left atrium, which results in atrial hypertrophy/dilation, which increases pressure/volume in the pulmonary circulation & causes PULMONARY EDEMA - Simplified:...

What can Reactive Oxygen Species cause? AnsHeart disease, Alzheimers, Parkinsons, Amyotrophic Lateral Sclerosis (ALS), CV disease, HTN, HLD, DM, ischemic heart disease, HF, OSA. Lipid perioxidation, damage proteins, fragment DNA, less *protein synthesis*, chromatin destruction, damage mitochondria How are free radicals produced? Ans1. Normal cellular respiration 2. Absorption of extreme energy sources (radiation, UV light) 3. Metabolism of exogenous chemicals, drugs, and pestici...

Antibodies appear _________ days after an antigen invades the body Ans6-7 Secondary immune response is also known as _________ immune response AnsAnamnestic The pathogenesis of ___________ is related to antibody/antigen complexes which are deposited in tissues/organs and triggers the immune response AnsLupus ___________ ____________ ________________ is derived from the fatty acids in the plasma membrane. This substance can be produced by neutrophils, monocytes, endothe...

E. Cells decrease in size P. Still functional; imbalance between protein synthesis and degradation. Essentially there is an increase in the catabolism of intracellular organelles, reducing structural components of cell Physiologic: thymus gland in early childhood Pathological: disuse (muscle atrophy d/ decrease workload, pressure, use, blood supply, nutrition, hormonal stimulation, or nervous stimulation) AnsAtrophy E: cells increase in number, mitosis (cell division) must occ...

Intravascular Fluid Compartment Ans8% of TBW It's the Blood Plasma Pattern of Fluid Shifts: blood pressure, vascular resistance Interstitial Fluid Compartment Ans25% of TBW It's the: fluid between cells, lymph, GI, spinal, eye/synovial fluids Pattern of Fluid Shift: between plasma and interstitial: 4 starling forces Intracellular Fluid Compartment Ans67% of TBW Its inside the cells Water moves freely across PM through aquaporin:ions trhough channel or transporter ...

NURS5315 EXAM 1 CELLULAR FUNCTION, CANCER, GENETICS QUESTIONS AND CORRECT DETAILED ANSWERS (VERIFIED ANSWERS) ALREADY GRADED A+

Cardiac Blood Flow Anso From body o Through: Vena cavas Right atrium Tricuspid valve Right ventricle Pulmonic valve Pulmonary artery o To lungs Pulmonary vein Left atrium Mitral valve Left ventricle Aortic valve

Anaplasia AnsLoss of cellular differentiation Benign tumors are AnsNon cancerous cells Leukemia AnsBlood condition of white cells (leukocytes); malignant (cancerous) condition. Cancer Cells (What do they do?) AnsCells that Ignore signals that instruct normal cells to stop cellular division and trigger apoptosis. Benign tumor characteristics AnsNon-malignant new growth. They do not spread to locally or distant sites. They are well encapsulated. Benign Tumor AnsDo...
