1 what structures pass through?
Foramen rotundum
(middle cranial fossa/pterygopalatine fossa)
V2 Maxillary division of V (trigeminal nerve)
62
2 what structures pass through?
Foramen ovale
(middle cranial fossa/infratemporal fossa)
V2 Mandibular division of V (trigeminal nerve)
63
3 what structures pass through?
Carotid canal
(middle cranial fossa/neck)
Internal carotid artery
64
4 what structures pass through?
Foramen spinosum
(middle cranial fossa/infratemporal fossa)
Middle meningeal artery
65
5 what structures pass through?
Jugular foramen
(posterior cranial fossa/neck)
IX glossopharyngeal nerve
X Vagus nerve
XI accessory nerve
Internal jugular vein
66
6 what structures pass through?
Foramen magnum
(posterior cranial fossa/neck)
Spinal cord
Vertebral arteries
Roots of accessory nerve (XI) pass from upper region of spinal cord through the foramen magnum into the cranial cavity and then leave the cranial cavity through the jugular foramen
67
7 what structures pass through?
Hypoglossal canal
(posterior cranial fossa/neck)
XII hypoglossal nerve
68
8 what structures pass through?
Internal acoustic meatus
(posterior cranial fossa/ear, and neck via stylomastoid foramen)
VII Facial nerve
VIII Vestibulocochlear nerve
Labyrinthine artery and vein
69
9 what structures pass through?
Foramen lacerum
Filled with cartilage in life
70
10
Superior orbital fissure
(middle cranial fossa/orbit)
V1 Ophthalmic division of V trigeminal nerve
III Oculomotor nerve
IV Trochlear nerve
VI Abducent nerve
Superior ophthalmic vein
71
11
Optic canal
(middle cranial fossa/orbit)
II Optic nerve
Ophthalmic artery
72
2
ethmoidal cells
72
12
Cribiform plate
(anterior cranial fossa/nasal cavity)
I Olfactory nerve
73
Being aware of air-filled
spaces within the skull is
essential. They are
identifiable on
radiographs.
Name the air-filled spaces
and correspond them to
the x-ray images.
1
frontal sinuses
74
3
maxillary sinuses
75
4
frontal sinus
75
5
sphenoidal sinus
76
what is this and what bones meet here?
pterion, frotnal, parietal, temporal and sphenoid
77
what is the pterion? why is it clinically relevant?
Pterion is the weakest part of the skull but contrary to belief, is not the thinnest part
Pterion has the middle meningeal artery running internally to it, therefore a crack can lead to internal bleeding and increased pressure in the brain (intracranial bleeding)
78
name 4 differeences between female and male skull
