Шаблон:Short description

Шаблон:Infobox boneThe chiasmatic groove (chiasmatic sulcus, optic groove, prechiasmatic sulcus) is a transverse[1] groove upon the superior aspect of the body of sphenoid bone[1][2]Шаблон:Rp within the middle cranial fossa.[2]Шаблон:Rp It is bounded anteriorly by the sphenoidal limbus (a variably prominent ridge also representing the posterior boundary of the sphenoidal jugum[3]), and posteriorly by the tuberculum sellae.[1] The opening of each optic canal is placed at either lateral end of the chiasmatic sulcus. The optic chiasm is situated superior and quite posterior to the chiasmatic groove (and not against the groove as the name suggests).[2]Шаблон:Rp
