Structure of synapse

- Transmits info from 1 neuron to another through neurotransmitters - Neurons separated by small gap, synaptic cleft - Neuron that releases neurotrans. called presynaptic neuron - Axon of this neuron ends in swollen portion, synaotic knob - This possesses many mitochondria + large amounts of endoplasmic reticulum - These required in manufacture of neurotrans., takes place at axon - Neurotrans. stored in synaptic vesicles - Once NT released from vesicles, diffuses to postsynaptic neuron, possesses specific receptor proteins on its membrane to receive it
