File Name: 5 types of neurotransmitters and their functions .zip
Neurotransmitters are endogenous chemicals that enable communication within the nervous system and between the nervous system and the rest of the body.
These target cells may be in glands, muscles, or other neurons. Billions of neurotransmitter molecules work constantly to keep our brains functioning, managing everything from our breathing to our heartbeat to our learning and concentration levels. They can also affect a variety of psychological functions such as fear, mood, pleasure, and joy. In order for neurons to send messages throughout the body, they need to be able to communicate with one another to transmit signals. However, neurons are not simply connected to one another.

Notably, emerging data suggest that cancer cells take advantage of the neurotransmitters-initiated signaling pathway to activate uncontrolled proliferation and dissemination.
In addition, neurotransmitters can affect immune cells and endothelial cells in the tumor microenvironment to promote tumor progression. Therefore, a better understanding of the mechanisms underlying neurotransmitter function in tumorigenesis, angiogenesis, and inflammation is expected to enable the development of the next generation of antitumor therapies.

What are neurotransmitters?
Axon Growth and Guidance pp Cite as. In the mature brain, neurotransmitters are used for synaptic communication between neurons. But during nervous system development, neurons often express and release transmitters before their axons establish contacts with their target cells. While much is known about the synaptic effects of neurotransmitters, their extrasynaptic effects are less understood. There is increasing evidence that neurotransmitters in the immature nervous system can act as trophic factors that influence different developmental events such as cell proliferation and differentiation. However, more recent work demonstrates that neurotransmitters can also influence the targeting of migrating neurons and growing axons during the formation of neuronal circuits.

Neurotransmitters are chemical messengers in the body. Their job is to transmit signals from nerve cells to target cells. These target cells may be in muscles, glands, or other nerves. Nerve cells, also known as neurons, and their neurotransmitters play important roles in this system.
Neurotransmitters are endogenous chemicals that transmit signals from a neuron to a target cell across a synapse. Although some neurons produce and release only one kind of neurotransmitter, most make two or more and may release one or more at any given time. The coexistence of more than one neurotransmitter in the synapse makes it possible for the cell to exert several influences at the same time. Major elements in neuron-to-neuron communication : Chemical synapses are specialized junctions through which neurons signal to each other and to non-neuronal cells such as those in muscles or glands. Neurotransmitters are packaged into synaptic vesicles clustered beneath the membrane in the axon terminal on the presynaptic side of a synapse. They are released into and diffuse across the synaptic cleft, where they bind to specific receptors in the membrane on the postsynaptic side of the synapse. Release of neurotransmitters usually follows arrival of an action potential at the synapse, but may also follow a graded electrical potential.
Neurotransmitters all serve a different purpose in the brain and body. Although there are several different minor and major neurotransmitters, we will focus on these major six: acetylcholine, dopamine, norepinephrine, serotonin, GABA, and glutamate. Neurotransmitters are chemical molecules synthesized within brain cells, which allow the transfer of signalling messages between brain cells. Whilst the signals which are carried within each cell are electrical, chemicals, such as neurotransmitters, are critical at the joins between cells to enable the transfer of information across the gaps. There are many major and minor signalling chemicals in the brain. The major neurotransmitters in your brain include glutamate and GABA, the main excitatory and inhibitory neurotransmitters respectively, as well as neuromodulators including chemicals such as dopamine, serotonin, norepinephrine and acetylcholine. Acetylcholine ACh is an important neurotransmitter in the brain which has a role in how you pay attention, learn and remember.

Беккер посмотрел на нее внимательнее. К ней как-то не шло сквернословие - как неуместны сточные воды в хрустальном графине. Но, приглядевшись, он убедился, что она вовсе не такая изысканная особа, как ему показалось вначале. Веки припухли, глаза красные, левая рука у локтя - вся в кровоподтеках с синеватым отливом. Господи Иисусе, - подумал .
- Он положил руку ей на плечо. - Я никогда не послал бы туда Дэвида, если бы считал, что это связано хоть с малейшей опасностью. - Он улыбнулся. - Поверь .
