axon terminals


Also found in: Dictionary, Thesaurus, Encyclopedia, Wikipedia.

ax·on ter·mi·nals

the somewhat enlarged, often club-shaped endings by which axons make synaptic contacts with other nerve cells or with effector cells (muscle or gland cells). Axon terminals contain neurotransmitters of various kinds, sometimes more than one. These can be demonstrated by chemical analysis and immunocytochemical methods.
See also: synapse.

axon

the process of a nerve cell along which impulses travel away from the cell body. It branches at its termination, forming synapses at other nerve cells or effector organs. Many axons are covered by a myelin sheath formed from the cell membrane of a glial or Schwann cell.

axon hillock
the elevation on the perikaryon from which the axon emerges.
axon reflex
a nerve impulse conducted through nerve pathways limited to the single axon, without the participation of a nerve cell or synapse. Not a true reflex.
axon telodendrion
extensive terminal branches of the axon before terminating on the effector organ.
axon terminals
the axonal structure capable of forming a synapse with another axon.

6) Increased inhibitory feedback on the axon terminal
These reuptake inhibitors, as the names suggest, target the reuptake transporter molecules in the axon terminal and prevent the removal of serotonin and noradrenaline from the synapse.
These opioid peptide-containing vesicles often are found in the same axon terminals with the smaller diameter, small molecule-containing vesicles, and thus many neurons have the capacity to release both small molecule and opioid peptide neurotransmitters (Kandel et al.
The endocannabinoids often are produced by postsynaptic neuronal elements and act on their cognate receptors, cannabinoid 1 (CBI) receptors, which are found almost exclusively on presynaptic axon terminals in the brain.
