Neuroanatomy - The dcml dorsal column medial lemniscus - A song and dance

The spinal cord has many, many, fibers going up and down, going up and down. The aff'rent sens'ry information travels, right up the back (posterior). They travel somatotopic'lly upwards, they're organized, they're organized. The caudad information's in the middle, the cephalad, is on the sides. Proprio-ception and vibration! Fine touch, two-point, it's the D-C-M-L! Posterior funiculus, posterior funiculus! Da-dada-dada posterior funiculus! Proprio-ception and vibration! Fine touch, two-point, it's the D-C-M-L! Posterior funiculus, posterior funiculus! Da-dada-dada posterior funiculus! The medial portion of the funiculus: fasciculus gracilis. The lat'ral portion of the funiculus: fasciculus cuneatus. Below T6 there is no cuneatus, unless your arms, come out your butt. And both, gracilis and cuneatus decussate, after they hit their nucleus. Proprio-ception and vibration! Fine touch, two-point, it's the D-C-M-L! Posterior funiculus, posterior funiculus! Da-dada-dada posterior funiculus! Proprio-ception and vibration! Fine touch, two-point, it's the D-C-M-L! Posterior funiculus, posterior funiculus! Da-dada-dada posterior funiculus! The primary neurons of the DC-ML are very long (they're much too long). They travel from the sensory receptors, up to the cau-dal medulla. The secondary neurons turn into the medial lemniscus. And after synapsing on the thalamus, the third ones go to the sensory cortex. Proprio-ception and vibration! Fine touch, two-point, it's the D-C-M-L! Posterior funiculus, posterior funiculus! Da-dada-dada, posterior funiculus! This song's so long, it will never end! At least second year is just around the bend. This song's too long, this song's too long, this song's too long, this song's too long! I think it should end now, because this song’s too long!
