Membrane potent Study guides, Class notes & Summaries

Mastering A&P - Membrane Potential Ions are unequally distributed across the plasma membrane of all cells. This ion distribution creates an electrical potential difference across the membrane. What is the name given to this potential difference? - correct answer Resting Membrane Potential (RMP) Sodium and potassium ions can diffuse across the plasma membranes of all cells because of the presence of what type of channel? - correct answer Leak channels On average, the resting membrane poten...

What is Modified Release? - The term modified-release is used to describe dosage forms that alter the timing and/or the rate of release of a conventional drug product/dosage form - FDA does define this Some Modified Release Systems - - some of these have overlap 1. Delayed release 2. Repeated Release or Repeat Action 4. Extended, Sustained, Long-Acting, Prolonged, Controlled Release 5. Targeted Release Delayed-release - - dosage forms release the drug at a later time than an immedia...

3.5 Resting Membrane Potential (RMP)Resting Membrane Potential - correct answer electrical potential energy by separation of oppositely charged particles across plasma membrane in all cells Voltage - correct answer -difference in electrical charge between two points -Voltage occurs only at membrane surface -Rest of cell and extracellular fluid are neutral -Membrane voltages range from -50 to -100 mV in different cells (negative sign (-) indicates inside of cell is more negative relative to...

Factors that maintain a Resting Membrane PotentialResting Membrane Potential: - correct answer Exists because of a small buildup of negative ions in the cytosol alone the inside of the membrane, and an equal buildup of positive ions in the extracellular fluid alone the outside surface of the membrane. Factor #1 - correct answer *Unequal distribution of ions in the ECF and cytosol. Extracellular fluid is rich in Na+ and Cl- Cytosol- main cation is K+ -Plasma membrane typically has mor...

Anatomy & Physiology I Chapter 4 [Section 4 Resting Membrane Potential]Resting membrane potential - correct answer the difference in charges across plasma membrane of excitable cell at rest What are the 2 cellular conditions significant in establishing and maintaining RMP? - correct answer 1.) Cell has unequal distribution of ions & molecules across plasma membrane. 2.) Relative amounts of positive & negative charges aren't equally distributed at plasma membrane What are the 2 ions respo...
