___________ is a large, irregular opening just medial to the styloid process, between the temporal and occiptal bones.
jugular foramen
__________ bone forms the rear of the skull and much of its base. Its features the foramen magnum, admits the spinal cord to the cranial cavity and provides a point of attachment for the dura mater.

hypoglassal canal
Prominent medial bump called the ______________________; the attachment for the nuchal ligament, which binds the skull to the vertbral column.
external occipital protuberance
_______________ has complex shape with a thick medial body and outstretched greater and lesser wings, which give the bone as a whole a somewhat ragged mothlike shape.
sphenoid bone
_____________ is an anterior cranila bone located between the eyes,
ethmoid bone

facial bones
____________ form the upper jaw and meet each other at a median intermaxillary suture.
____________ form the rest of the hard plate, part of the wall of the nasal cavity, AND part of the floor of the orbit.
palatine plate
