Crista galli in the center of the frontal bone and important anchor for the dura of the brain. Cribiform plate bone with perforated holes from nose to brain for smell. Hypophyseal fossa/pituitary fossa pituitary gland sits here; resembles a saddle. Dorsum sellae the (cid:271)a(cid:272)k of the (cid:858)saddle(cid:859) Occipital bone primarily made of the posterior fossa. Temporal bone the petrous part is the ridge part of bone that separates middle from posterior fossa. Lobes = frontal, parietal, temporal, occipital, insula is behind temporal. Pre-central gyrus: motor function, behind the frontal lobe, separated from the post-central gyrus by the central sulcus. Post-central gyrus: pri(cid:373)ary se(cid:374)sory; you do(cid:374)(cid:859)t k(cid:374)o(cid:449) (cid:449)hat you(cid:859)re tou(cid:272)hi(cid:374)g, (cid:271)ut you(cid:859)re tou(cid:272)hi(cid:374)g so(cid:373)ethi(cid:374)g. **pre and post-central gyrus are contralateral to the sides pf the body they control.
