alright Ninja nerds to give you guys another view of the brain of some of the internal structures so first off if you remember from before we had this central sulcus here on the side and this little groove right here this little groove running right there this guy right there is actually called the central sulcus, so again the central sulcus is this little like groove right here running all the way up right there and what's the purpose of it? the central sulcus seperates the frontal lobe from the parietal lobe so if i come up the
central sulcus one more time if i go right in front of the sulcus to this gyrus right there cos remember a sulcus is like this divid)?) and then a gyrus is this big fat lumpy thing right there this gyrus in front of the central sulcus is called the precentral gyrus it's also where the primary motor cortex is. and if i follow the central sulcus back up again and i go to this fat gyrus that's right behind it that guy right there is called the post central gyrus and that's where the primary somatosensory cortex is aight
if i were to in front of the primary motor
