7587652919 | Synaptic gap | The minute space between the cell membrane of an axon terminal and of the target cell with which it synapses. Also called synaptic cleft . | 0 | |
7587652920 | Receptor | These chemicals diffuse across the synapse (the gap) and bind with receptor molecules on the membrane of the next neuron | 1 | |
7587652921 | Neurotransmitter | Chemical messengers, that when released influence other neurons. | 2 | |
7587652922 | Synaptic vesicles | Tiny sacs like water balloons filled with neurotransmitters. | 3 | |
7587652923 | Nerve impulse | A nerve impulse is an electrical signal that travels along an axon. There is an electrical difference between the inside of the axon and its surroundings, like a tiny battery. | 4 | |
7587652925 | Postsynaptic membrane | The cell/neuron that RECEIVES the message. | 5 | |
7587652926 | Axon | The long thread-like part of a nerve cell along which impulses are conducted from the cell body to other cells. | 6 | |
7587652927 | Dendrite | A short branched extension of a nerve cell, along which impulses received from other cells at synapses are transmitted to the cell body. | 7 | |
7587666378 | Synaptic Reuptake | Neurotransmitters are not destroyed but reused. | 8 | |
7587680255 | lock and key model | Transmitter molecules will only will only affect the postsynaptic membrane if that molecule's shape fits into certain synaptic receptor molecules - like a key into a lock. | ![]() | 9 |
7587998175 | Presynaptic Neuron | The cell/neuron that SENDS the message. | 10 | |
7588012060 | Postsynaptic | The cell/neuron that RECEIVES the message. | 11 |
