Anatomy Flashcards
Olfactory nerve
CN1
Olfactory nerve Passes where?
Through the Cribiform plate to go to olfactory bulb
Optic Nerve
CNII
Oculomotor nerve
cranial nerve CNIII
Oculomotor nerve originates…?
from the oculomotor nucleus and the Edinger-Westphal nucleus within the midbrain of the brainstem.
Oculomotor nerve Passes through… to reach where?
It passes through the cavernous sinus and proceeds through the supraorbital fissure to reach the orbit of the eye
Trochlear Nerve
CNIV
Superior oblique muscle Innervated by what?
Trochlear nerve, cranial nerve IV
______ is the only cranial nerve to exit from the posterior midbrain
Trochlear nerve,
The ______ (IV) nerve moves along the lateral wall of the cavernous sinus before entering the __________ via ______
(Trochlear) -Orbit of the eye via the superior orbital fissure.
Three branchess of Trigeminal nerve are…
ophthalmic (V1), maxillary (V2), and mandibular (V3) nerves.
Ophthalmic nerve (V1), Travles….
passes forward in the lateral wall to the cavernous sinus. It then enters the orbit via the superior orbital fissure * Branch of Trigeminal Nerve V
Maxillary Nerve.(V2) (From..) trigeminal ganglion, Leaves the skull through ?
Foramen rotundum
The mandibular nerve (V3) exits the skull base through
Foramen ovale.
Of the 3 branches of Trigeminal (CN?) Which ones are sensory and Which are motor?
V3 is the only branch which contains both sensory and motor components
The Opthalmic (V1) and Maxillary (V2) nerves contain only sensory fibres.
