Vesicles can also fuse with other target cell compartments, such as a lysosome ... | https://en.wikipedia.org/wiki/Vesicle_fusion |
The vesicular monoamine transporter (VMAT) is a transport protein integrated into the membranes of synaptic vesicles of presynaptic neurons . It transports monoamine neurotransmitters – such as dopamine , serotonin , norepinephrine , epinephrine , and histamine – into the vesicles , which release the neurotransmitters ... | https://en.wikipedia.org/wiki/Vesicular_monoamine_transporter |

The solute carrier family 18 member 2 ( SLC18A2 ) also known as vesicular monoamine transporter 2 ( VMAT2 ) is a protein that in humans is encoded by the SLC18A2 gene . [ 5 ] VMAT2 is an integral membrane prot... | https://en.wikipedia.org/wiki/Vesicular_monoamine_transporter_2 |
Vesicular transport adaptor proteins are proteins involved in forming complexes that function in the trafficking of molecules from one subcellular location to another. [ 2 ] [ 3 ] [ 4 ] These complexes concentrate the correct cargo molecules in vesicles that bud or extrude off of one organelle and travel to another loc... | https://en.wikipedia.org/wiki/Vesicular_transport_adaptor_protein |
Vespertine is a term used in the life sciences to indicate something of, relating to, or occurring in the evening. In botany , a vespertine flower is one that opens or blooms in the evening. [ 1 ] In zoology , the term is used for a creature that becomes active at dusk , such as bats and owls. Strictly speaking, howeve... | https://en.wikipedia.org/wiki/Vespertine_(biology) |
A vessel traffic service is a marine traffic monitoring system established by harbour or port authorities, similar to air traffic control for aircraft. The International Maritime Organization defines vessel traffic service as "a service implemented by a competent authority designed to improve the safety and efficiency ... | https://en.wikipedia.org/wiki/Vessel_traffic_service |
Vestibular paroxysmia (VP) is a rare vertigo syndrome, which is defined by recurring, short-lasting vertigo attacks. A neurovascular cross-compression is commonly assumed to cause these attacks. [ 1 ] [ 2 ]
The main symptoms of VP are short attacks lasting seconds to a few minutes with spinning or swaying vertigo , wh... | https://en.wikipedia.org/wiki/Vestibular_paroxysmia |
A vestigial response or vestigial reflex in a species is a response that has lost its original function. In humans, vestigial responses include ear perking, goose bumps and the hypnic jerk .
It has been observed that some people have slight protrusions on the outer ear (also known as the auricle). These protrusions te... | https://en.wikipedia.org/wiki/Vestigial_response |
Vestigiality is the retention, during the process of evolution , of genetically determined structures or attributes that have lost some or all of the ancestral function in a given species. [ 1 ] Assessment of the vestigiality must generally rely on comparison with homologous features in related species. The emergence o... | https://en.wikipedia.org/wiki/Vestigiality |
