  2. Axon terminal - Wikipedia

    en.wikipedia.org/wiki/Axon_terminal

    Axon terminals (also called terminal boutons, synaptic boutons, end-feet, or presynaptic terminals) are distal terminations of the branches of an axon. An axon, also called a nerve fiber, is a long, slender projection of a nerve cell that conducts electrical impulses called action potentials away from the neuron's cell body to transmit those ...

  3. Synaptic vesicle - Wikipedia

    en.wikipedia.org/wiki/Synaptic_vesicle

    The area in the axon that holds groups of vesicles is an axon terminal or "terminal bouton". Up to 130 vesicles can be released per bouton over a ten-minute period of stimulation at 0.2 Hz. [ 1 ] In the visual cortex of the human brain, synaptic vesicles have an average diameter of 39.5 nanometers (nm) with a standard deviation of 5.1 nm.

  4. Dendrodendritic synapse - Wikipedia

    en.wikipedia.org/wiki/Dendrodendritic_Synapse

    An incoming action potential permits the release of neurotransmitters to propagate the signal to the post synaptic cell. There is evidence that these synapses are bi-directional, in that either dendrite can signal at that synapse. Ordinarily, one of the dendrites will display inhibitory effects while the other will display excitatory effects. [1]

  5. Cellular extensions - Wikipedia

    en.wikipedia.org/wiki/Cellular_extensions

    Many of the extensions are cytoplasmic protrusions such as the axon and dendrite of a neuron, known also as cytoplasmic processes. Different glial cells project cytoplasmic processes. In the brain , the processes of astrocytes form terminal endfeet , foot processes that help to form protective barriers in the brain.

  6. Dendrite - Wikipedia

    en.wikipedia.org/wiki/Dendrite

    A dendrite (from Greek δένδρον déndron, "tree") or dendron is a branched cytoplasmic process that extends from a nerve cell that propagates the electrochemical stimulation received from other neural cells to the cell body, or soma, of the neuron from which the dendrites project.

  7. Axon - Wikipedia

    en.wikipedia.org/wiki/Axon

    The swollen end of a telodendron is known as the axon terminal or end-foot which joins the dendrite or cell body of another neuron forming a synaptic connection. Axons usually make contact with other neurons at junctions called synapses but can also make contact with muscle or gland cells.

    When you buy a bottle of vitamins from a nutrition store, you’ll probably notice a best-by date on the bottom of the jar. But that inscribed number isn’t a hard-and-fast rule—there is some ...

  9. Grey matter - Wikipedia

    en.wikipedia.org/wiki/Grey_matter

    Grey matter, or gray matter in American English, is a major component of the central nervous system, consisting of neuronal cell bodies, neuropil (dendrites and unmyelinated axons), glial cells (astrocytes and oligodendrocytes), synapses, and capillaries.
