Terms Related to Synaptic Terminal

• 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 ...

• 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 ...

• 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 ...

• Neuropils

  A dense intricate feltwork of interwoven fine glial processes, fibrils, synaptic terminals, axons, and dendrites interspersed among the nerve cells in the gray matter of ...

• 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.

• 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 ...

• Sympatholytics

  Drugs that inhibit the actions of the sympathetic nervous system by any mechanism. The most common of these are the ADRENERGIC ANTAGONISTS and drugs that ...
