sub·stan·ti·a ge·lat·i·no·sa

 (səb-stăn′shē-ə jə-lăt′n-ō′sə)
n.
A narrow, dense, vertical band of gray matter forming the dorsal part of the posterior column of the spinal cord whose gelatinous appearance is due to its very low content of myelinated nerve fibers. It functions in the integration of sensory stimuli that give rise to the sensations of heat and pain.
[New Latin substantia gelatinōsa : Latin substantia, substance + New Latin gelatinōsus, gelatinous.]
