Neurotransmitters are chemicals that are used to relay, amplify and modulate signals between a neuron and another cell.
Neurotransmitters are broadly classified into small-molecule transmitters and neuroactive peptides.
neurotransmitters
endogenous signaling molecules that alter the behaviour of neurons or effector cells.
neurotransmitters Chemicals released from the tip of an axon into the synaptic cleft when a nerve impulse arrives; may stimulate or inhibit the next neuron.
neurotransmitter
A chemical messenger released from the synaptic terminal of a neuron at a chemical synapse that diffuses across the synaptic cleft and binds to and stimulates the postsynaptic cell.
neutral variation ...
Neurotransmitter A chemical messenger that passes signals between nerve cells or between a nerve cell and another type of cell.
Nuclear envelope A barrier that encloses the nucleus and is made up of two membranes perforated by nuclear pores.
Neurotransmitter A small, diffusible molecule, such as acetylcholine, that mediates the passage of nerve impulses across the synapse.
Some neurotransmitters
Acetylcholine (ACh) Widely used at synapses in the peripheral nervous system. Released at the terminals of ...
Define 'neurotransmitter'.
A neurotransmitter is a small molecule chemical that's released from one neuron and diffuses to a second neuron, and binding to that neuron will transduce a signal between the two neurons.
Neurotransmitters tend to be small molecules, some are even hormones. The time for neurotransmitter action is between 0,5 and 1 millisecond.
Neurotransmitters can be excitatory or inhibitory. Each muscle is enervated by both kinds. Endocrine glands or exocrine glands, the other kind of effector cells or organs, respond by releasing their product when stimulated by a motor neuron.
neurotransmitter Chemical substance secreted by the terminal end of an axon that stimulates a muscle fiber contraction or an impulse in another neuron.
neurotransmitter - small signaling molecule secreted by the presynaptic nerve cell at a
chemical synapse to relay the signal to the postsynaptic cell. Examples include acetycholine, glutamate, GABA, glycine, and many neuropeptides ...
6.8 Neurotransmitters and drugs.
Illustrates normal activity as well as the effect of various drug classes on neurotransmitter activity and reuptake (e.g. selective serotonin reuptake inhibitors or SSRIs).
6.9 Mitosis ...
Based on radioligand binding studies, it has long been assumed that the neurochemical pathology of Alzheimer's disease (AD) does not involve widespread changes in post-synaptic neurotransmitter function.
Although, redox-active neurotransmitters were detected directly with high sensitivity, non-electroactive DNA could only be detected using indirect detection.
Pertaining to nerves that release the neurotransmitter norepinephrine/noradrenaline (e.g. adrenergic nerves, adrenergic response). An alternative U.S. useage also pertains to the receptors acted upon by noradrenaline, i.e. adrenergic receptors.
Another example is the translocation of vesicles containing neurotransmitters by microtubules to the tips of nerve cell axons.
acetylcholinesterase (AChE) - an enzyme that catalyzes hydrolysis of the neurotransmitter acetylcholine into acetate and choline. Expression of AChE can serve as a marker of skeletal muscle differentiation.
Junction between two nerve cells, consisting of a minute gap across which impulses pass by diffusion of a neurotransmitter ...
the locus where one neuron communicates with another neuron in a neural pathway; a narrow gap between a synaptic terminal of an axon and a signal-receiving portion (dendrite or cell body) of another neuron or effector cell. Neurotransmitters released ...
