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.

Temporal Bone External acoustic/auditory meatus A canal that leads to the eardrum and the middle ear – sound enters ear here

Temporal Bone Styloid process Sharp, needlelike projection Inferior to external auditory meatus Used as attachment point for neck muscles

Temporal Bone Zygomatic process Thin bridge of bone that joins with zygomatic bone

Temporal Bone Mastoid process Projection posterior and inferior to external auditory meatus Attachment site for some muscles of the neck

Temporal Bone Jugular foramen At junction of occipital and frontal bone Allows passage of jugular vein (largest vein of the head)

Occipital Bone Occipital condyles Lateral to foramen magnum on each side First vertebra rest on these

Maxilla/Mandible Alveolar margin Region of upper jaw where teeth are carried

Mandible Condylar process Forms temporomandibular joint with temporal bone
