1. Anatomy: Bone

Question 1

Answer 1

Foramen Rotundum

Question 2

Answer 2

Foramen Spinosum and Ovale

Think of this as a footprint of a woman’s high heeled shoe

Oval - Ovale
Heel - Spinosum

Question 3

Answer 3

Hypoglossal canal

Question 4

The jugular foramen

Answer 4

Two parts:

1.Pars Nervosa:
Nervous guy in front
Contains: Glossopharyngeal Nerve (IX)
with it’s tympanic branch: “Jacobson’s Nerve”

2. Pars Vascularis
   Vascular part
   Contains: Jugular bulb along with the Vagus Nerve (X), Auricular branch “Arnold’s Nerve, and Spinal Accessory Nerve (XI)

Question 5

Orbital Fissures and the PPF

Answer 5

The relationship of this 4 is an important one

1. Superior orbital fissure (SOF)
2. Inferior orbital fissure (IOF)
3. Forament Rotundum (FR)
4. Pterygopalatine fossa (PPF)

Question 6

Cavernous Sinus

What runs through it?

What do NOT run through it?

Answer 6

The question is most likely, what’s in it (or asked as what is NOT in it)

Run through it.
CN3 (Occulomotor)
CN4 (Trochlear)
CNV1 (Trigeminal - ophthalmic)
CNV2 (Tigeminal - Maxillary)
CN6 (Abducens)
Carotid
CN 3, CN 4, CN VI, CN V2, CN 6, and the carotid

do NOT run through it
CN 2 (Optic) and CN V3 (Tigeminal Mandibular)

CN6 runs next to the carotid

Theres tof the nerves run along the wall.

This is why you can get lateral rectus palsy earlier with cavernous sinus pathologies (CN6 -abducens affected)

Question 7

Internal Auditory Canal

Answer 7

The Thing to remember
7UP COKE Down

CN7 (Facial nerve) is superior to the CN8 (Vestibulocochlear nerve)

Ideal Sequence to find it: T2WI with supercuts throght the IAC
