The 
mastoid process is a conical prominence projecting from the undersurface of the 
mastoid portion of the temporal bone .  It is located

mastoid process ,
Kaynak: MastoiditisThe structure of the squama is like that of the other cranial bones: the 
mastoid portion is spongy, and the petrous portion dense and hard.

mastoid process  of the temporal bone of the cranium shows it to be hollowed out into a number of spaces, the

mastoid antrum (tympanic antrum, antrum mastoideum, Valsalva's antrum) is an air space in the petrous portion of the temporal bone ,

mastoid foramen is a large hole in the posterior border of the temporal bone .  It transmits a

mastoid process  is a deep groove, the 
mastoid notch (digastric fossa), for the attachment of the Digastricus .

mastoid antrum (entrance or aperture to the 
mastoid antrum), is a large irregular
