(17 cards)
describe the layers of the skull bone.
compact bone lies inferior and superior with spongy bone called diploe in between
what are the 4 sutures of the skull and which bones do they separate?
sagittal- 2 parietal bones
lambdoid- parietal and occipital
squamous- parietal and temporal
coronal- parietal and frontal
what is and where is the nasion?
midline depression between the eyes where the frontal and 2 nasal bones meet
what is the glabella?
area of skin between the eybrows
what is the supraorbital notch?
small opening in the central edge of the superior orbital margin where the supraorbital nerve, artery and vein pass through
what is the tempo mandibular joint?
connects the mandible via the condyloid process to the temporal bone and moves the jaw
what is the stylomastoid foramen and what passes through it?
between the styloid and mastoid processes on the temporal bone which the facial nerve passes through
what is the external occipital protuberance?
middle of the squamous part of the occipital bone
how many cervical vertebrae are there?
7
what kind of curvature does the cervical region have?
lordosis
what is special about the spinous processes of the cervical vertebrae?
they are bifid
what is the vertebra prominens?
the long spinous process of C7
what is special about the transverse processes of the cervical vertebrae and what passes through them?
foramen transversarium- vertebral artery, vein and plexus of sympathetic nerves
what is special about C1?
it is called the atlas
what is special about C2?
it is called the atlas and has a unique odontoid process (dens)
how does C1 join with the skull?
atlanta-occipital joint- atlas to occipital condyles of the occipital bone which is a synovial ellipsoid joint
what is the connection between C1 and C2?
atlanti-axial joint which is a synovial pivot joint
