Which of the following is NOT a type of channel used in production of electrical signals in neurons?Group of answer choicesLigand-gated channelVoltage-gated channelIon-gated channelLeakage channelMechanically gated channel

Which of the following is false regarding Na+ ion channels in a neuron?Group of answer choicesTheir concentrations are highest at the nodes of Ranvier.Na+ can move from an area of high concentration inside a cell to an area of low concentration outside the cell through these channels.They permit the movement of Na+ ions in only one direction.The Na+ ion channels are integral membrane proteins.

Which statement regarding the diversity of ion channels is false?Select one:Select the correct definitionWith only six different types, potassium channels are the least diverse channel type.There are at least 10 different sodium channels in humans.Sodium channels that do not inactivate have been found.There are least 10 different types of calcium channels.Calcium channels serve diverse functions such as influencing action potential shape and mediating the release of neurotransmitters.
