Neuromodulatory molecule that plays several important roles in cells.
In the brain, dopamine functions as a neurotransmitter—a chemical released by neurons (nerve cells) to send signals to other nerve cells.
Neuron
21 linksElectrically excitable cell that communicates with other cells via specialized connections called synapses.
Electrically excitable cell that communicates with other cells via specialized connections called synapses.
The axon terminal is found at the end of the axon farthest from the soma and contains synapses. Synaptic boutons are specialized structures where neurotransmitter chemicals are released to communicate with target neurons. In addition to synaptic boutons at the axon terminal, a neuron may have en passant boutons, which are located along the length of the axon.
Chemical synapse
16 linksChemical synapses are biological junctions through which neurons' signals can be sent to each other and to non-neuronal cells such as those in muscles or glands.
Chemical synapses are biological junctions through which neurons' signals can be sent to each other and to non-neuronal cells such as those in muscles or glands.
At a chemical synapse, one neuron releases neurotransmitter molecules into a small space (the synaptic cleft) that is adjacent to another neuron.
Acetylcholine
15 linksAcetylcholine (ACh) is an organic chemical that functions in the brain and body of many types of animals (including humans) as a neurotransmitter.
Norepinephrine
19 linksNorepinephrine (NE), also called noradrenaline (NA) or noradrenalin, is an organic chemical in the catecholamine family that functions in the brain and body as both a hormone and neurotransmitter.
Amino acid
13 linksAmino acids are organic compounds that contain amino (\sNH3+) and carboxylic acid (\sCO2H) functional groups, along with a side chain (R group) specific to each amino acid.
Amino acids are organic compounds that contain amino (\sNH3+) and carboxylic acid (\sCO2H) functional groups, along with a side chain (R group) specific to each amino acid.
Beyond their role as residues in proteins, amino acids participate in a number of processes such as neurotransmitter transport and biosynthesis.
Glutamic acid
9 linksAn α-amino acid that is used by almost all living beings in the biosynthesis of proteins.
An α-amino acid that is used by almost all living beings in the biosynthesis of proteins.
It is also the most abundant excitatory neurotransmitter in the vertebrate nervous system.
Serotonin
15 linksMonoamine neurotransmitter.
Monoamine neurotransmitter.
Axons from the neurons of the raphe nuclei form a neurotransmitter system reaching almost every part of the central nervous system.
Monoamine neurotransmitter
8 linksMonoamine neurotransmitters are neurotransmitters and neuromodulators that contain one amino group connected to an aromatic ring by a two-carbon chain (such as -CH2-CH2-).
Synaptic vesicle
6 linksIn a neuron, synaptic vesicles (or neurotransmitter vesicles) store various neurotransmitters that are released at the synapse.
