When unmyelinated axons are checked for laminin, only nascent laminin is found in situ.    From Wordnik.com.  [CreationWiki - Recent changes [en]]

It also requires much less sodium than the unmyelinated axons do because it does not employ the use of a sodium-potassium pump.    From Wordnik.com.  [CreationWiki - Recent changes [en]]

When nerve cells are unmyelinated, the axon has a smaller diameter and contains neurofilaments that are less modified and are more compact.    From Wordnik.com.  [Kansas City infoZine Headlines] Reference

If we have unmyelinated and myelinated axons and they can vary in diameter, how exactly do we have people who are specialists on these things.    From Wordnik.com.  [Serendip's Exchange -] Reference

Other planned experiments will focus on how electrical signals travel through myelinated and unmyelinated nerves to reveal how nerves malfunction.    From Wordnik.com.  [Nano Tech Wire] Reference

In summary, the factors favoring the triggering of pain by either unmyelinated C-fibers or myelinated Aδ-fibers include the low/high rate of stimulation, the low/high base temperature of the skin and the short/long peripheral path.    From Wordnik.com.  [PLoS ONE Alerts: New Articles] Reference

The data demonstrated a direct neuroregenerative effect of SB-509 treatment that resulted in a statistically significant (p value = 0.02) increase in small unmyelinated nerve fibers in the skin, or intraepidermal nerve fiber density (IENFD), in subjects with DN.    From Wordnik.com. Reference

Although we did not make a formal determination of the conduction velocity of the fibers that triggered the sensation of warmth, the psychophysical latencies of the warm responses were found to be compatible with unmyelinated C-fibers at the faster end of their range (~2 m/s).    From Wordnik.com.  [PLoS ONE Alerts: New Articles] Reference

These receptors are called "nociceptors" and are free nerve endings connected to small diameter myelinated A and unmyelinated C nerve fibers - these are the nerve fibers that are LACKING in people with congenital insensitivity to pain (here is more information about nerve fibers).    From Wordnik.com.  [Recently Uploaded Slideshows] Reference

Nociceptors (AMH) conducting at medium velocities and unmyelinated polymodal C-nociceptors (CMH) conducting at low velocities, there are two subcategories characterized by slowly (Type I) and rapidly (Type II) adapting responses to stepped heat stimuli, respectively.    From Wordnik.com.  [PLoS ONE Alerts: New Articles] Reference
