U neuronima, sinaptičke vezikule (ii neurotransmiterske vezikule) služe za skladištenje raznih neurotransmitera koji se oslobađaju u sinapsi. Oslobađanje je regulisano naponom-kontrolisanim kalcijumskim kanalima. Vezikule su esencijalne za propagaciju nervnoh impulsa između neurona i ćelije ih konstantno ponovno formiraju. Oblast aksona koja sadrži grupe vezikula je aksonski terminal ili buton. Do 130 vezikula se može osloboditi po butonu tokom desetominutne stimulacije na 0.2 Hz.[1] U regionu V1 ljudskog mozga sinaptičke vezikule imaju prosečni prečnik od 39,5 nanometera sa standardnom devijacijom od 5,1 nanometara.[2]

List of recoilless rifles

This is a list of recoilless rifles (RCLs) intended to catalogue these lightweight infantry support weapons that allow the firing of a heavier projectile than would be practical with a recoiling artillery gun. Technically, only devices that use a rifled barrel are recoilless rifles. The smoothbore variants (those devoid of rifling) are termed recoilless guns. This distinction is often lost, and both are often called recoilless rifles. Normally used for anti-tank roles, the first effective sy...
