What is Anosmia
loss of smell
What is anosmia generally associated with
upper respiratory infections, sinus disease and head trauma

Coronal suture
Which suture seperates the parietal bones
Sagittal suture
Which suture seperates the parietal and temporal bones from the occipital bone
lambda suture
What is bregma
craniometric landmark formed by the intersection of coronal and sagittal sutures
What is the sella turcica
a bony structure formation on the upper surface of the body of the sphenoid, surrounded by anterior and posterior clinoid processes
Where is the superior orbital fissure located
between the greater and lesser wings, opens anteriorly
where is the foreamen rotundum
posterior to medial end of superior orbital fissue,
what and where is the foreamen ovale
large foreamen posterolateral to foreamen rotundum, open inferiorly to infratemporal fossa
What and where is the foreamen spinosum
located lateral to foreamen ovale, also opens inferiorly into infratemporal fossa
Which cranial fossa houses the cerebellum, pons and medulla oblongata
posterior cranial fossa
Which fossa houses the inferior and anterior parts of the frontal lobes
anterior cranial fossa
What can you find in the middle cranial fossa
sells turcica and large depressed lateral parts on the sphenoid on each side
Which cranial fossa is the deepest
Posterior Cranial fossa
Which facial bone was once called the Malar bone
zygomatic bone
What is it called when a surgeon removes a bone flap in the skull and then replaces it
craniotomy
what is is called when a surgeon removes a bone flap in the skull and does not replace the bone flap
crainiectomy
What passes through the supraorbital foreamen
supra-orbital nerve and vessels
What passes through the infraorbital foreamen
infra-orbital nerve and vessels
What is the name of the foreamen found at the lateral aspect of the zygomatic bones
zygomaticofacial foramen
What nerve passes through the stylomoastiod foramen
facial nerve
Describe the difference between Lefort fracture I, II and III?
I-fracture above the upper lip in the maxilla
II-fracture lateral from the maxilla sinuses through the medial aspect of the infra-orbital foramina
III- horizontal fracture that passes through the ehtmoid, nasal bones, superior orbital fissures and wings of the sphenoid bone
