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.
1 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. neuron transports its information by way of a nerve impulse called an action potential. When an action potential arrives at the synapse's presynaptic terminal button, it may stimulate the release of neurotransmitters.
