LET’S REVIEW THE BONES OF THE SKULL

Human Skull. Human Skull – 22 bones 2 parts: 1.Cranium (8 bones fused at sutures) – protects brain, provides muscle attachment, sinuses reduce weight.

Chapter 7 The Skeleton Part A.

Skull Usually consists of 22 bones, all of which (except the lower jaw) are firmly interlocked along lines called “sutures”. Cranium = 8 bones Facial skeleton.

THE SKULL SIMPLY, AMAZING!. Most complex bony structure 22 bones in all Mostly flat bones, but not all!

Presentation transcript:

Cranial Bones, continued….. Temporal bones On each side of the skull Joins parietal bone (squamosal suture) Form parts of sides and base of cranium External auditory meatus (???) Mandibular fossae – depressions in the temporal bone that articulate with condyles (???) of the mandible What does “meatus” mean? (passage) What could the external auditory meatus be?

Cranial Bones, continued….. Temporal bones, continued…. Below each external auditory meatus: Mastoid process – rounded attachment for certain neck muscles Styloid process – long, pointed anchor for muscles associated with tongue and pharynx Zygomatic process Projects anteriorly (???) from temporal bone, joins the zygomatic bone (“cheek bone”), and helps form prominence of the cheek
