hi I'm Kristy this is my extra credit project for neuro ot 441 with professor Stein something you should know about me is that I'm not musical I don't write songs and I'm not a poet but I do want extra honey so I'll give it a try I compose two songs about the different tracks that we learned about and they are both set to children's tunes so hopefully they will be familiar to you this first one is about the DC ml tract and to orient you let me show you that this is a finger this is
the dull end of a safety pin and this says touch so we'll be discussing the touch of dole end of a safety pin on the finger and magical journey that it takes sending the information all the way up to the postcentral decks so let's get started with a DC ml tract which is set to the tune of none other than the itsy-bitsy spider all right the DC ml tract can be confusing the you ease our lateral fasciculus cuny itís the Elie's are more medial fasciculus gracilis and the medial lemniscus is attractive white matter first order
neuron goes in the dorsal root it's still laterally protects up the dorsal column then it terminates in the medulla where it lands in the nucleus matching the dorsal column second order neuron starts in the medulla decussate to the sides via the medial lemniscus up through the cerebrum into the thalamus where the VP of the thalamus it's Lester third-order neuron starts in the VPO through the internal cat so which is just white matter then out it comes at synapses on the brain on the post central gyrus of the parietal lobe primary somatosensory cortex that is where
this info finally ends up responding to touch by some proprioception the Macan where you step Darrius got the job done d see ya
