Axo-axonic synapses are found throughout the central nervous system, including in the hippocampus, cerebral cortex and striatum in mammals; [3] [4] [5] in the neuro-muscular junctions in crustaceans; [6] [7] and in the visual circuitry in dipterans. [8] Axo-axonic synapses can induce either inhibitory or excitatory effects in the postsynaptic ...
From your first comment, Debivort, you raise the issue of the synapse being connected to the soma, but this is not necessarily wrong, as presynaptic axons often synapse with postsynaptic neuron's body, creating an axosomatic synapse. Not all synapses are axodendritic synapses. See this image. There are some issues to clear up with the terms ...
A neuromuscular junction (or myoneural junction) is a chemical synapse between a motor neuron and a muscle fiber. [1] It allows the motor neuron to transmit a signal to the muscle fiber, causing muscle contraction. [2] Muscles require innervation to function—and even just to maintain muscle tone, avoiding atrophy.
In both images neurons are stained with a somatodendritic marker, microtubule associated protein (red). In the right image, synaptic vesicles are stained in green (yellow where the green and red overlap). Scale bar = 25 μm. [3] Synaptic vesicles are relatively simple because only a limited number of proteins fit into a sphere of 40 nm diameter.
In neuroscience, the axolemma (from Greek lemma 'membrane, envelope', and 'axo-' from axon [1]) is the cell membrane of an axon, [1] the branch of a neuron through which signals (action potentials) are transmitted.
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 impulses to other neurons, muscle cells, or glands.

Presynaptic inhibition is a phenomenon in which an inhibitory neuron provides synaptic input to the axon of another neuron (axo-axonal synapse) to make it less likely to fire an action potential. Presynaptic inhibition occurs when an inhibitory neurotransmitter, like GABA , acts on GABA receptors on the axon terminal .
