The 12 Cranial Nerves

• I. Olfactory nerve.
• II. Optic nerve.
• III. Oculomotor nerve.
• IV. Trochlear nerve.
• V. Trigeminal nerve.
• VI. Abducens nerve.
• VII. Facial nerve.
• VIII. Vestibulocochlear nerve.

What cranial nerves are in cerebellopontine angle?

Within the cerebellopontine angle, the superior vestibular nerve is posterior and superior, the facial nerve anterior and superior, the inferior vestibular nerve posterior and inferior, and the cochlear nerve anterior and inferior.

Are there two foramen of Luschka?

The lateral apertures (of Luschka) (also known as the foramina of Luschka) are two of the foramina in the ventricular system and link the fourth ventricle to the cerebellopontine cistern.

What is magendie and Luschka?

After a very long period of studies on CSF and its pathways, the openings of the 4th ventricle, which communicate with the two compartments (ventricular and subarachnoid), were discovered thanks to Magendie (median) and Luschka (lateral) and later named after them.

Where is foramen of Luschka and magendie?

The median aperture (foramen of Magendie) opens on midline into a subarachnoid space inferior to the cerebellum called the cisterna magna and into the quadrigeminal cistern in the region of the tectum of the midbrain. Two lateral apertures (foramen of Luschka) also open into the cisterna magna.

Which cranial nerves are only Motors?

Cranial nerves I, II, and VIII are pure sensory nerves. Cranial nerves III, IV, VI, XI, and XII are pure motor nerves.

What is 6th cranial nerve?

Cranial nerve six (CN VI), also known as the abducens nerve, is one of the nerves responsible for the extraocular motor functions of the eye, along with the oculomotor nerve (CN III) and the trochlear nerve (CN IV).

What is the cerebellopontine angle?

Cerebellopontine angle (CPA) is a triangular space in the posterior cranial fossa that is bounded by the tentorium superiorly, brainstem posteromedially and petrous part of temporal bone posterolaterally.
