RMP questions with 100% correct answers rated A+ 2023

-RMPMost neurons have same basic structure - correct answer A cell body with a number of dendrites and one long axon with its terminals. What is the defining characteristic of neurons? - correct answer Have the property of electrical excitability • Ability to produce action potentials or impulses in response to stimuli • Have the property of electrical conductivity • Ability to propagate action potentials or impulses What is the function of different parts of neuron? - correct answer synaptic terminais conduct ap to other neuron dendrities and cell body recieve signal axon conduct ap describe charge of Resting Membrane Potential : Cocked gun - correct answer Neuron's membrane at rest are more negatively charged inside than outside - polarised - Resting state About - 70 to - 90 milliVolts Active metabolically Resting "Electrically" - Excess of -ve ions inside and excess of +ve ions outside note - correct answer When the cells are excited they lose their "polarity" - depolarised • Such depolarisation when "Explosive" - Action Potential - Language of Neurons axon hillock - correct answer Cone shaped region of an axon where it joins the cell body. and generate ap it has Na and k pump why ap cant be generated in other parts - correct answer no voltage channel and less na k pump RMP for large neuron is more - like example - correct answer skeletal muscle what do we mean by resting - correct answer no change electricly ( charge) example of the anion inside the membrane - correct answer phosphate and protein donnas gibbs law - correct answer Unequal distribution of ions which cell doesnt have Na K PUMp - correct answer nothing all the cells have this pump why Sodium-potassium pump is electrogenic - correct answer responsible for charge difference around membrane interpret K leakes more than Na - correct answer Equilibrium Potential - correct answer stop k movement chemical and electrical gradient are equal but opposite Equilibrium Potential: measured by - correct answer Nernst Equation EMF(mV) = ± 61 log Concentration outside Concentration inside driving force - correct answer Electromotive force - Equilibrium potential - Univalent ion - EMF is (-) if cation diffuses from inside to outside - EMF is (+) if cation diffuses from outside to inside - Reverse signs for anion
