  • nerve
  • An amino acid neurotransmitter is an amino acid which is able to transmit a nerve message across a synapse . (wikipedia.org)
  • neurotransmitters After Galvani had shown, in 1742, that electrical stimulation of the nerve to the muscle of a frog's leg caused the muscle to twitch, the idea gained ground that transmission from nerves to the 'end organ' was an electrical process. (encyclopedia.com)
  • To detect neurotransmitters is a difficult task as the amounts released are minute and mechanisms exist that quickly remove the transmitter, leaving the system in a state of readiness for the arrival of the next nerve impulse. (encyclopedia.com)
  • Based on earlier work it had been hypothesized that the small electron-lucent vesicles observed by electron microscopy in cholinergic nerve terminals contained and released quantal packages of the neurotransmitter. (wikipedia.org)
  • uptake
  • Such neurotransporter cotransport systems are highly diverse, as recent development indicates that uptake systems are generally selective and associate with a specific neurotransmitter. (wikipedia.org)
  • biosynthetic
  • Many neurotransmitters are synthesized from simple and plentiful precursors such as amino acids , which are readily available from the diet and only require a small number of biosynthetic steps for conversion. (wikipedia.org)
  • sympathetic
  • Dale was not convinced that the sympathetic neurotransmitter was adrenaline itself, because he demonstrated subtle differences between the responses to the transmitter and to adrenaline. (encyclopedia.com)
  • physiological
  • There are many neurotransmitters in the body, all of which work together to regulate motor coordination, behavior, temperature, pain mechanisms, blood flow and many other biochemical and physiological properties. (factbites.com)
  • We are learning that neurotransmitters play a key role in controlling behavior , and understanding how they work has become a vital part of physiological psychology. (mhhe.com)
