Possible Additional Questions Flashcards
What can you tell me about the Carotid canal?
Within temporal bone
Where the internal carotid artery enters the middle cranial fossa from the neck
main blood supply to the head
What can you tell me about the Eustachian Tube?
A small passageway that connects your throat to your middle ear.
When you sneeze, swallow, or yawn, Eustachian tubes open. Keeps air pressure and fluid from building up inside the ear.
Eustachian tube can get plugged = Eustachian tube dysfunction
What can you tell me about the Jugular Foramen?
large opening in base of skull located behind the carotid canal
Formed by the temporal bone and the occipital bone.
Allows many structures to pass; inferior petrosal sinus, three cranial nerves, the sigmoid sinus, and meningeal arteries.
Cranial nerves 9,10,11 (glosso pharyngeal, vagus and accessory)
What can you tell me about the Superior Orbital Fissure?
nerves III, IV and VI (oculo-motor, trochlear and abducens)
+
Ophthalmic branch of trigeminal nerve V
What can you tell me about the Stylo-mastoid Foramen?
between styloid and mastoid processes of temporal bone
termination of the facial canal
facial nerve and stylomastoid artery
What can you tell me about the Hypo-glossal canal?
in occipital bone of skull
hypo- glossal nerve XII
What can you tell me about the Internal Auditory Meatus?
canal within the petrous part of the temporal bone of the skull
between the posterior cranial fossa and the inner ear
transmits nerves and vessels from within the posterior cranial fossa to the auditory and vestibular apparatus
What can you tell me about the Pterygoid plates?
part of the sphenoid
origin of the lateral and medial pterygoid muscle
which working with the masseter allows us to chew
What can you tell me about the Vomer?
small, thin, plow-shaped
divides the nasal cavity
Forms the septum
articulates with the sphenoid, ethmoid, palatines and maxillae
What can you tell me about the Palatines?
situated at the back of nasal cavity between the maxilla and the pterygoid process of the sphenoid bone
articulates with sphenoid, ethmoid, maxillae, inferior nasal concha, vomer
What can you tell me about the Inferior Nasal Conchae?
one of the three paired nasal conchae in the nose
other nasal concha forms part of ethmoid = superior concha and middle concha
What can you tell me about the Confluence of Sinuses?
Posterior of the cranium where falx cerebri, falx cerebelli and tentorium cerebelli meet
Forms the junction of sinuses: - transverse, straight, inferior/superior, occiputal.
Facilitates blood drainage from the superior sagittal, straight and occipital sinuses to the bilateral transverse sinuses that carry the blood towards the internal jugular vein
