Fasciculus gracilis and cuneatus

Hey guys.. Let's draw the sensory tracts that are found within the dorsal white column of the spinal cord!
Might as well read about em too ^_^

What I like to do is write down the points with the diagrams [As you guys already know]
So lemme present to you.. my notes! =D

Their primary responsibility is to carry sensory information regarding discriminative senses (viz., proprioception, vibration, stereognosis, and two-point discrimination) to higher centers
I've drawn a feather for fine touch, tuning fork for vibration and closed eye for stereognosis! [In case you didn't understand ^_^ ]

Here is the description point wise.. :)

Sensory regions covered by Cuneatus and Gracilis mnemonic
GRAcilis - Walk GRAcefully (Lower extremities and lower trunk)
CunEATus - EAT with your hands (Upper extremities and upper trunk)

Remember: Crude touch is NOT carried by this tract
It is carried by the anterior spinothalamic tract

That's all :)



This is express yourself space. Where you type create something beautiful! <3
Wondering what do I write? Well...
Tell us something you know better. You are a brilliant mind. Yes, you are! ^__^
Ask about something you don't understand @_@?
Compliment... Say something nice! =D
Be a good critic and correct us if something went wrong :|
Go ahead. Comment all you like here! (:
