Q: normally, which of the following will happen after a neurotransmitter binds to its receptor?

A: A neurotransmitter is a signalling chemical released by a neuron and transmitted across a synapse to…

Q: What happens to the membrane potential inside and outside of the cell when Ca+ channels are open?

A: Membrane potential is a potential gradient that forces ions to passively move in one direction where…

Q: Calcium ions a)Help control the membrane threshold voltage. b)Reduce axon permeability to Na+.…

A: sensory input-afferent information travels from the outside environment to brain environment.

Q: After an action potential has been initiated, there are two processes that prevent the membrane from…
