synaptic transmission

Question 1

synapses

Answer 1

signals pass through synapses to neurons when action potential reaches the end of a neuron.
triggers release of a chemical substance (neurotransmitter) which disperses across the synapse
the neurotransmitter binds to receptor molecules on the next neuron (postsynaptic) and generates a new action potential.

Question 2

neurotransmitter

Answer 2

chemicals that are realsed from a synaptic vessel into the synapse by neurons
then taken “back up” into the terminate buttons of neurons through the processes or reuptake or they are broken down by an enzyme

Question 3

process

Answer 3

neurons transmit signals electrically along their axons
at the synapses signals are transmitted chemically using neurotransmitters.
nt binds to the receptor molecules on the next neuron, realeasing a new action potential.
