Expert Solution

Step 1

Anatomy

The dorsal column-medial lemniscus mechanism (DCML) is a nervous system sensory path. It gives the skin and joints a sense of fine touch, movement, pain, two-point distinction and proprioception. The spinal cord's white matter is divided up into columns of the dorsal (or posterior), lateral(anterior) and ventral (or anterior) columns, each comprising axon tracts related to particular roles. The dorsal columns bring from somatic mechanoreceptors ascending sensory information. The lateral columns contain axons that migrate to spinal motor neurons from the cerebral cortex to contact.
