Synaptic Transfer

electrical impulse

electrical impulse

The opening of ion channels generates a(n) ________ in the post- synaptic neuron, propagating the pre- synaptic signal.

Synapses

________: junctions between neurons and between neurons and receptor or effector cells.

Nerves

________ transmit electrical impulses by changing the ionic distribution across the neuronal membrane (membrane potential)

Neurotransmitters

________ bind to specific receptors on the post- synaptic membrane and open ligand- gated ion channels.

Neurons

________ transmit information across synapses by converting the electrical signal into a chemical signal.

enzymatic activity

The neurotransmitters released into the synapse are either recycled (by reuptake pumps) or degraded (by ________)

axon terminal

The neurotransmitters are released from the ________ by exocytosis and cross the synaptic cleft.

Calcium ions

________ (Ca2+) diffuse into the cell and promote the fusion of vesicles (containing neurotransmitter) with the cell membrane.

Synapses

junctions between neurons and between neurons and receptor or effector cells
