nervous system
hypermyelination ( J:90038 , J:145464 )
• hypermyelination; thickened myelin sheath observed on the sciatic nerve (J:90038)
• more pronounced for smaller caliber axons than large caliber axons (J:90038)
• many moderately hypermyelinated axons in the white matter due to additional spiral wraps (J:145464)
• extent of remyelination after lysolecthin injection is no greater than for controls (J:145464)
