What is a hormone and how does it act? - ANSWER-Hormones are chemical messengers that are responsible for regulation. They are secreted into body fluids, mainly blood. It has specific actions on target tissues, which are any tissue that has specific receptors for that particular hormone. What is a paracrine gland? - ANSWER-a secretion that enters interstitial fluid but affects only neighboring cells What is an autocrine gland? - ANSWER-A secretion that only affects the secreting cell. W...

The Plasma Membrane and Membrane Potential Mod 1 questions with correct answers

Membrane PotentialDo all living cells have a membrane potential? - correct answer UMM YESH What is a membrane potential? - correct answer Difference in charge inside/outside the cell membrane What is electrical potential? - correct answer When opposite charges are separated they have the potential to do work if allowed to come together What 2 ways can electrical force increase? - correct answer Quantity of charge, decreased charge separation What is the RMP of a typical neuron? - cor...

Resting Membrane Potential Electrical gradients (such as the transmembrane voltage or RMP) only affects what kind of molecules? - correct answer The RMP is needed for the Na+-dependent cotransport of glucose, amino acids & other solutes into cells. 2.) What is the range of magnitudes (in millivolts) of the resting membrane potential (RMP) of human cells? - correct answer The magnitude of the RMP is between - 20 millivolts(mV) and - 100 mV, depending upon cell type & activity. 3.) Is the i...

Test Bank for Guyton and Hall Textbook of Medical Physiology, 14th Edition Chapter 05 - Membrane Potentials and Action Potentials

Resting Membrane Potential & Action PotentialAction Potential - correct answer Abrupt, pulsatile changes in membrane potential. Property of excitable cells that consists of rapid depolarization followed by repolarization. AP's have same size & shape; are propagating; and are "all or nothing". Resting Membrane Potential - correct answer Undisturbed period of action potential when nerve is NOT transmitting impulses. Cell membrane is said to be polarized-inside of cell more negatively cha...

Resting Membrane Potential Electrical gradients (such as the transmembrane voltage or RMP) only affects what kind of molecules? - correct answer Charged molecules What is the range of magnitudes (in millivolts) of the resting membrane potential (RMP) of human cells? - correct answer -20 to -100mv Is the inside of the cell electrically negative, or electrically positive, RELATIVE to the extracellular fluid? - correct answer negative How many volts is a millivolt? - correct answer 10^-3 ...

BIOL 235 Human Anatomy and Physiology Assignment 3 Questions and correct Answers (Correctly Explained). 1. Some patients who suffer from hypertension (high blood pressure) are prescribed medications that are in the category of angiotensin-converting enzyme (ACE) inhibitors. Explain why these drugs are used to combat hypertension. When blood volume falls or blood flow to the kidneys decreases, juxtaglomerular cells in the kidneys secrete renin into the bloodstream. In sequence, renin and ang...

Quiz 2- Membrane PotentialIons 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 potential is -7...
