Skull: 22 bones Has holes that allow passage for nerves
Sutures- visible seams on surface Spongy bone is called dipolë
Most of cranial roof and walls Forehead to coronal suture
Bordered by s , Passage for nerves is called supraorbital foram
and squamous sutures Smooth area above nose is called glabella
Rear and base of skull Squamous part is squam
Foramen magnum admits suture
the spinal cord to cranial Tympanic part borders

Superior nuchal line defines Mastoid part is posterior
superior limit of neck to tympanic part
Petrous part separates
middle cranial from post
Anterior cranial bone Form upper jaw
Pair of sphenoid sinuses between eyes Palate forms roof of
