Bow Covers. Bow covers snap over the entire front open-bow area of your boat and can serve several purposes. Use them for storage to protect from UV rays and rain, or snap them in place to create a âclosed-bowâ effect on your boatâwhich is helpful when boating in the rain or cold weather.ow Covers.

Neurotransmitters are stored in a synapse in synaptic vesicles, clustered beneath the membrane in the axon terminal located at the presynaptic side of the synapse. Neurotransmitters are released into and diffused across the synaptic cleft, where they bind to specific receptors in the membrane on the postsynaptic side of the synapse.
The released neurotransmitter may then move across the synapse to be detected by and bind with receptors in the postsynaptic neuron. Binding of neurotransmitters may influence the postsynaptic neuron in either an inhibitory or excitatory way. Enzyme degradation â special chemicals called enzymes break it down. 2  Reuptake â re-absorption of a neurotransmitter into the neuron. 3  Transporters, or membrane transport proteins, pump neurotransmitters from the synaptic cleft back into axon terminals (the presynaptic neuron) where they are stored.
