They send silent status updates about balance and posture directly to the cerebellum without the brain having to "think" about it.
From receptor to the spinal cord (Dorsal Root Ganglion). 2nd Order: From the spinal cord/brainstem to the thalamus. 3rd Order: From the thalamus to the cerebral cortex.

pathways. They carry sensory data from your peripheral receptors (like your skin and joints) up to the brain for processing. Dorsal Column-Medial Lemniscus (DCML) System They send silent status updates about balance and
The white matter of the spinal cord is divided into three pairs of columns: the anterior, lateral, and posterior funiculi. Each column contains bundles of axons called tracts. These tracts are named based on their origin and destination. Generally, tracts starting with "spino-" are ascending (sensory), while those ending in "-spinal" are descending (motor).
