WebMay 29, 2024 · Mitochondria accumulate within nerve terminals and support synaptic function, most notably through ATP production. They can also sequester Ca2+during nerve stimulation, but it is unknown whether this limits presynaptic Ca2+levels at physiological nerve firing rates. Do axon terminals connect to dendrites? WebApr 17, 2024 · Axonal transport of mitochondria is tightly linked to mitochondrial dynamics as mitochondrial fusion requires the coalescence of mitochondria and fission requires the active separation of dividing organelles. WebAxon Terminals At the end of the axon are axon terminals, also called synaptic terminals or boutons. These structures contain synaptic vesicles filled with neurotransmitters that are released into the synapse, or the small gap between neurons, when an action potential reaches the terminals.
