Unit 2 - Bio-psychology - The Synapse Flashcards

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
