Head- foramen Flashcards
ECVDI
A orbital fissure
B rostral alar foramen leading to alar canal, round foramen inside the skull
What goes through the rostral alar canal?
Maxillary branch of trigeminal (V)
what nerves go through the orbital fissure?
III, IV, opht V, VI, sympathetic innervation to the eye
what goes through the round foramen?
Maxillary branch of trigeminal (V)
What goes through the oval foramen?
Mandibular branch of CN V
How does the facial nerve exit the skull?
through the internal acoustic meatus, in to the facial canal and out the stylomastoid foramen
what nerves pass through the facial canal?
Facial and vestibulocochlear (VII, VIII)
What structures pass through the jugular foramen?
Jugular vein, CN IX, X, XI, sympathetic innervation to the eye in tympano- occipital fissure
Where does the hypoglossal nerve (CN XII) exit the skull?
Hypoglossal canal, occipital bone
hypoglossal canal
A dorsum sella B oval foramen
alar canal
orbital fissure
jugular foramen
trigeminal canal
A round foramen, alar canal
optic nerve
Trigeminal canal in the petrous temporal bone
Oval foramen; mandibular nerve, middle meningeal artery
Internal acoustic meatus, facial canal
What is the name of the hole? Where does it exit the skull?
Jugular foramen, Tympano-occipital fissure
osseous tentorium cerebella, hypoglossal canal
jugular foramen- Tympano-occipital fissure; CN IX, X, XI (internal & external branches), internal carotid artery, sympathetic fibers to the head
Malleus, incus, stapes. Tensor tympani m. attaches to the malleus (inn. mandibular n.). Also, the stapedius m. (the smallest skeletal muscle in the body!) attaches to the stapes (the smallest bone in the body), inn. VII.
