Draw details of the repolarization phase of an action potential from the following descriptions of the sequences of AfterHyperPolarization (AHP) and AfterDePolarization (ADP) sequences. Make the distinct phases clear and noticeable (5 % each) A complex AHP consisting of a first component AHP, an ADP, and a second component AHP before repolarization to resting membrane potential a first fast AHP component, followed by a slower AHP, followed by a fast ADP, and a second late AHP component before repolarization to rest

Match the events listed with their order in the mechanisms behind the firing of an action potential under normal conditions (without tetrodotoxin present in the man's body). The cell has a resting membrane potential of -65 mV. You should match these events at the initial segment of a bipolar neuron. Please note that this is a sequence question. Although not an option below, you should consider that neurotransmitters are bound to ligand-gated receptors causing EPSPs. Now, put the process in the correct sequence: **arrange from 1-10

1) A 100-um diameter nerve axon has the following properties: rm = 2.5 x 104 ohm x cm, ri = 1 x 105 ohm/cm, r0 = 0, cm = 3 x 10-8 F/cm. The permeability to Cl- is very high and Cl- ions are at resting potential Vm. A steady inward current is injected into the axon resulting in a Vm of -110 mV at the site of current injection. If the Vm 3 mm from the site of injection is -94.5 mV, what is the resting Vm?
