Spotter Prep Flashcards
- What is the name giving to this structure?
- What structures are present in the lateral grooves of this structure?
- Skull Cap or Calvaria
- Middle Meningeal Vessels
- What is the name giving to this structure?
Superior Saggital Sinus
- Identify the spaces labelled.
Anterior Cranial Fossa, Middle Cranial Fossa, Posterior Cranial Fossa
Identify the elevation.
What is the function of this structure?
Frontal fest and Christa Galli
Attachment of flax cerebri, olfactory bulbs run lateral to it
- Identify the elevation.
- What is the function of this structure?
Foramen caecum
It transmits the emissary vein from the noso the superior sagittal sinus.
This has clinical importance in that infections of the nose and nearby areas can be transmitted to the meninges and brain from what is known as the danger triangle of the face.

- This structure is perforated by what structures?
- Crista Galli
- Attachment of falx cerebri
- Olfactory bulbs
- Olfactory nerve rootlets
- Identify the depression.
- What structure is traversed through this depression if it is patent?
- The structure identified in 2. connects which two areas?
- When this structure is clinical significance if this structure is patent?
- Foramen caecum
- Emissary veins
- Nose to superior saggital sinus
- Infection can spread; meningitis
- Identify the structures.

2.What structure traverses this canal?
Foramen Lacerum
The artery of pterygoid canal, the nerve of pterygoid canal. Emissary Vein Internal carotid runs superiorly not through.
1.Identify the structure.
2.What produces this structure?
- Petrous Crest
- Sphenoid and occipital bones
Arcuate Eminence due to Superior Semicircular Canal.
- Identify the structure.
- What structures traverse this canal?
- Internal Acoustic Meatus
- transmits the vestibulocochlear nerve, the facial nerve, and the labyrinthine artery (an internal auditory branch of the basilar artery).
It also contains the vestibular ganglion.
- Identify the structure.
- What are the subdivisions of this structure?
- What structures traverse these subdivisions?
- Jugular Foramen
- Anterior Intermediate, posterior
- The anterior compartment transmits the inferior petrosal sinus and glossopharyngeal nerve (CN IX)
The intermediate transmits the vagus and accessory nerves (aka cranial nerves number X, and XI respectively).
The posterior transmits the sigmoid sinus (becoming the internal jugular vein) and some meningeal branches from the occipital and ascending pharyngeal arteries.
Internal jugular vein and petrosal sinus
- Identify the canal.
