a nerve cell
passes messages along to other neurons or to muscles
protects the axon from the electrical current passing through the neuron
chemical messengers that fit into to receptor sites and move messages from one neuron to another
Synaptic cleft / gap
tiny space between the axon terminal and dendrites where neurotransmission takes place
The neuron that send the message is the PRE- synaptic neuron the one that receives is the POST-synaptic neuron
Ends of axons that contain vesicles with neurotransmitters
Branchlike parts of a neuron that receive messages (neurotransmitters)
a neural impulse; a quick electrical charge that travels down an axon
the cell body of the neuron
Chemical signals between neurons, take chemical from one neuron, transmit it to another
