Axial Skeleton Flashcards
If you are touching your forehead what bone are you touching?
Frontal
“Where your unibrow grows”
Glabella
Where your non-unibrow eyebrow grows (bone)
Supraorbital margin
What is the hole where your eyebrows grow?
Supraorbital foramen
If you are touching the top of your head you are touching your __________ bone
Parietal
What is the suture between your parietal bones?
Sagittal
Suture between parietal and frontal?
Coronal
If you are touching your temples you are touching you _____ bone?
temporal
“Ear canal”
EAM- external auditory meatus
If you were a tiny human and walked through you EAM and looked back you would be looking at your ______
Internal auditory canal
___________: a bridge-like projection that articulates with the zygomatic bone to form the zygomatic arch
Zygomatic process
_________: is a protruding part of the bone that is most commonly associated with muscle attachment
Process
__________: located posterior to the external acoustic meatus, serves as an attachment for neck muscle
Mastoid process
________: located on the inferior surface of the zygomatic process and articulates with the condyle of your mandible
Mandibular fossa
______: suture between the temporal and parietal bone
Squamous suture
____________: Pen like projection found on the inferior part of the temporal lobe, posterior to the EAM. This process helps attach muscle and neck ligaments.
Styloid process
________: tiny hole found in between the Styloid process and the mastoid process that is responsible for the passage of cranial nerves
Stylomastoid foramen
_________: found in the inferior part of the skull in between the temporal and occipital bone, lateral to the occipital condyles
Jugular foramen
What canal is directly anterior to the jugular foramen?
Carotid artery
_________: forms the posterior aspect and most of the base of the skull
Occipital
What the “brain stem” hole
Foramen magnum
What part of your occipital articulates with your axis vertebrae?
Occipital condyles
What is the suture between the occipital and parietal?
Lambdoidal
____________: opening medial and superior to the occipital condyle through which nerves pass (found in the wall of the foramen magnum)
Hypoglossal canal
________: looks like a buttery fly and is found in the front part of the skull (inside), important due to it wide-spread articulation (articulates with all other cranial bones)
Sphenoid
_______: project laterally from the sphenoid body contributing to part of the middle cranial fossa and the orbital
Greater wings
___________: form part of the floor of the anterior cranial fossa and part of the orbital
In between the two wings of the sphenoid within the orbital is a veins and nerves run through a large fissure known as the ________ _________ ___________
Lesser wings
Superior orbital fissure
_______________: where your pituitary gland sits, the superior part of the sphenoid bones. Translates to Turkish saddle.
Sella turcica
