Default C)

Tractus Cuneatus ... It is the nucleus where axons from the first neurons of Dosal Coloumn Pathway synaps. Axons from the upper body synapse in nucleus cuneatus. Dorsal coloumn medial leminscus (DCML) pathway carries the sensation of stereognosis, fine touch, vibration & proprioception.

You use your FINGERS to perceive shap & size (discrimination) .. so it would be upper body sensation.

actually, you could have the same symptoms in your lower body (T gracilis), because you could also perceive shape and size with your toes, haha

:P obviously you have never steeped on a lego block or picking up a pen with your toes so you don't have to get up Of course you can sense an object with your toes . Think about blind people that sense carefully the ground where they are steeping to.

But if no other information is given to me I will think about upper body first
