appressa, the PeV1 axons in the vpn accelerated carbon grains on the pedal sole, while PeD7 axons that form the 5-HT-LIR pedal sole plexus were silent.

When testing axons for neuro-physiological identification within a peripheral nerve, there are several kinds of large group I axons.

Myelin is stripped, axons (nerve fibers) have broken, and entire nerve cells have died.

Within several days of crushing a peripheral nerve, the injured axons begin to regenerate through their distal pathway until they reach their original targets with which they restore neurological function.

Stem cells known as normal human neural progenitor (NHNP) cells develop into three types of brain cells: neurons, which receive and transmit electrical signals via axons and synapses; astrocytes, which manage neurons' surrounding environment; and oligodendrocytes, which produce myelin, the fatty sheath that insulates axons.

Also important are neurotrophic factors, often provided by glial cells, other axons, and glycoproteins located throughout the brain.

Light microscopic examination revealed a wide variation among the five vestibular nerves in the number, density, and size of myelinated axons. A characteristic feature of all nerves was the irregular appearance of the myelin (e.g., blebs and whorls) associated with medium- and large-diameter axons (figures 1, A, and 1, B).

Neurons have threadlike fibers called axons that send messages and branches called dendrites that receive them.

Neurons consist of a round cell body that sends signals over long, terminally branched processes, called axons, and receives signals from the axons of other neurons through multiple shorter processes, called dendrites.

Scientists are overturning the conventional wisdom found at the start of almost any spinal cord regeneration article: Nerve fibers (axons) in the brain and spinal cord do not regenerate naturally, even though peripheral nerves can.
