Scull, Meninges, Gross brain Flashcards
What are the 3 parts of the cranial fossae
Anterior, Middle, Posterior
What seperates the anterior and middle cranial fossae
spehnoidal crest
What seperates the middle and posterior cranial fossa
superior border of petrous part of temporal bone
Anterior cranial fossa is formed by which bones
Frontal, Ethmoid, Sphenoid
Which lobe of the brain does the anterior cranial fossa hold
frontal lobes
Which bones make up the middle cranial fossa
Sphenoid, parietal, temporal (petrous)
What part of the brain does the middle cranial fossa hold
temporal lobes
Which fossa does the temporal lobe sit in
middle
Which fossa does the frontal lobe sit in
anterior cranial fossa
Which bones make up the posterior cranial fossa
parietal, temporal, occipital
Which parts of the brain does the posterior cranial fossa hold
cerebellum and brainstem
Which fossa do the cerebellum and brainstem sit in
posterior cranial fossa
Which parts of the brain sit on the cranial fossa
Frontal lobes- Anterior fossa
Temporal lobes- middle fossa
Cerebellum and brainstem- Posterior fossa
What does dura mater split into medially
Periosteal dura (superficially) and meningeal dura (deeper)
What creates the venous sinus
Dura mater- creates tunnel for flow of CSF between Periosteal dura and meningeal dura
Where is CSF created
in ventricles
Where do vessels travel in brain
Between Arachnoid and pia mater
Which carotid goes into the brain
Internal carotid (external carotid provides blood to face, meninges, and scalp)
Which carotid supplies the face, meninges, and scalp
External carotid
What are the terminal branches of the external carotid artery
Maxillary artery and superficial temporal artery
Branches of trigeminal nerve
Opthalmic, Maxillary, Mandibular
If you are looking at veins, which layer are you in?
Arachnoid mater
If you see gyri and sulci, which layer of the brain are you in (no veins)
pia mater
