Bio 111L Skull
of the frontal bone transmits the supraorbital nerve and vessels which supply the skin of the forehead.
Supraorbital foramen
of the temporal bone articulates with the mandibular condyle in the temporo- mandibular joint
Mandibular fossa
is the outer ear canal to transmit sound waves to the ear.
External acoustic (auditory) meatus (canal)
processes of temporal bone are for muscles attachment.
Mastoid and styloid
is for the lower part of the brain to continue with the spinal cord
Foramen magnum of the occipital bone
articulate with the atlas in the atlanto-occipital joint.
The occipital condyles of the occipital bone
of the sphenoid bone houses the pituitary gland.
Sella turcica (hypophyseal fossa)
of sphenoid bone are located on each side of the posterior openings of the nasal cavities.
Pterygoid processes
forms the roof of the nasal cavity. It contains the olfactory foramina for the transmission of the fibers of the olfactory nerve.
Cribriform plate of ethmoid
forms the superior part of the nasal septum.
The perpendicular plate of ethmoid
on each side forms part of the medial wall of the orbit and forms the lateral wall of the nasal cavity.
The lateral mass of ethmoid
nasal conchae project from the lateral mass,
The superior and middle nasal conchae
Are processes of ethmoid
The superior and middle nasal conchae
, but the is a separate bone of the skull.
inferior nasal concha
transmits the infraorbital nerve and vessels.
Infraorbital foramen of maxilla
contains the alveolar sockets of the upper teeth.
Alveolar margin (process) of maxilla
form the anterior part of the hard palate.
Palatine processes of maxilla
Nasal septum is formed by the following
Superior: perpendicular plate of ethmoid Posterior and Inferior: vomer
Anterior: septal cartilage
transmits the nerve which supplies the lower teeth.
Mandibular foramen
transmits the mental nerve and vessels to supply the skin of the chin
Mental foramen
is for a muscle attachment.
Coronoid process
contains the alveolar sockets of the lower teeth.
Alveolar margin (process)
cribriform plate of ethmoid
Olfactory foramina
medial to lesser wing of sphenoid, between lesser wing and body
Optic canal
below lesser wing of sphenoid, between lesser and greater wing
Superior orbital fissure
anterior in the greater wing of sphenoid lateral to the body
Foramen rotundum
posterior in the greater wing of sphenoid lateral to the body
Foramen ovale
within the back of the temporal bone
Internal acoustic canal
between temporal and occipital bones
Jugular foramen
in the margin of foramen magnum
Hypoglossal canal
The lateral mass contains the
Ethmoid Air Sinuses.
