Synapses in which gap junctions allow ions to diffuse quickly from cell to cell are called ______ synapses.Multiple Choicechemicalelectrical

The chemical signals that diffuse across the synapse are called ____.Question 32Select one:a.neurotransmittersb.dentritesc.thoughtsd.neurons

Synaptic potentials are __________Blank potentials resulting from opening or closing __________Blank-gated ion channels.Multiple Choicelocal; chemicallyaction; voltageaction; chemically

What describes a synapse?Multiple choice question.junction between an axon and another cellgap in the myelin sheath along an axondepolarization that reaches a threshold levelthe time it takes it repolarize a neuron

Which of these descriptions about gap junctions are TRUE? Choose all the correct answers.Group of answer choicesThey allow cells to be electrically continuous for rapid communication of electrical impulses e.g. in optical relay neurons.They allow for co-ordinated behaviour of tissue e.g. co-ordination of heart beat.They can be voltage or ligand gated.They actively generate electrical potentials.

Connexons of gap junctions in electric synapses a- are Ligand-gatedb- are voltage-gatedc- allow transmission of potential changes in both directions between the pre- and post- synaptic neuronsd- close whenever the presynaptic neuron becomes hyperpolarized
