Naked axon region of a myelinated neuron
WitrynaAction potential velocity. Brain cells called neurons send information and instructions throughout the brain and body. The information is sent via electro-chemical signals known as action potentials that travel down the length of the neuron. These neurons are then triggered to release chemical messengers called neurotransmitters which help ... Witryna13 kwi 2024 · The axon diameters and myelin sheath thickness were also enhanced, resulting in the amelioration of muscle atrophy, nerve conduction, and motor function recovery. To explain this interesting phenomenon, western blot results indicated that the Gel-Ppy conduit facilitated nerve regeneration via upregulating the Rap1 pathway to …
