Terms Related to Presynaptic Nerve Ending

• Nerve Ending

  Specialized terminations of peripheral neurons. Nerve endings include NEUROEFFECTOR JUNCTION(s) by which neurons activate target organs and sensory receptors (see RECEPTORS, SENSORY) which transduce information …

• Synaptic Membrane

  Cell membranes associated with synapses. Both presynaptic and postsynaptic membranes are included along with their integral or tightly associated specializations for the release or reception …

• Presynaptic Receptor

  Neurotransmitter receptors located on or near presynaptic terminals or varicosities. Presynaptic receptors which bind transmitter molecules released by the terminal itself are termed AUTORECEPTORS.

• Autoreceptor

  Transmitter receptors on or near presynaptic terminals (or varicosities) which are sensitive to the transmitter(s) released by the terminal itself. Receptors for the hormones released …

• Synaptic Vesicle

  Membrane-bound compartments which contain transmitter molecules. Synaptic vesicles are concentrated at presynaptic terminals. They actively sequester transmitter molecules from the cytoplasm. In at least some …

• H3 Receptors

  A class of histamine receptors discriminated by their pharmacology and mode of action. Histamine H3 receptors were first recognized as inhibitory autoreceptors on histamine-containing nerve …
