Skull Osteology & Muscles of Facial Expression Flashcards
Which is not a function of the skull:
- support and contain the brain
- houses all the senses
- protection of the brain to some degree
- isolates the cerebral circulation
- houses all the senses
* the skull houses only the special senses sight, hearing, and smelling*
Which is not a function of the skull:
- barrier against stresses due to the large masticatory and axial musculature
- bony orbit maintains to position of the eye during rotations which is necessary for binocular vision
- bony fixation of semicircular canals necessary for their function
- protesting of spinal cord
- protection of spinal cord
Which bone of the skull contains:
- contains zygomatic process (small process for articulation with the zygomatic bone)
- contains supraorbital notch/foramen
- region of the forehead back to the coronal suture
Frontal Bone
Which bone of the skull contains:
- 2 bones joined at sagittal suture
- junction of coronal & sagittal sutures is called the bregma
- the suture between the parietal bones & occipital bone is called the lamboid suture
- junction of sagittal suture and lamboid suture is called the lambda
Parietal Bone
Which bone of the skull contains:
- external occipital protuberance (inion)
- superior nuchal line
- inferior nuchal line
Occipital Bone
Which bone of the skull contains:
- squamous part
- petrous part
- zygomatic process
- mandibular fossa
- mastoid process
- external-internal acoustic meatus
- styloid process
- stylomastoid foramen
Temporal Bone
Which bone of the skull contains:
- a body (internal base view) with optic groove, optic foramen, sella turcica
- a greater wing (internal base view) with a foramen rotundum, foramen ovale, and foramen spinosum
- lesser wings
- superior orbital fissure
- pterygoid process (medial and lateral pterygoid plates) (external base view)
Sphenoid Bone
Which bone of the skull contains:
- cribiform plate
- crista galli
Ethmoid Bone
Which FACIAL bone contains:
- body: infr-orbital foramen
- zygomatic process
- frontal process
- alveolar process
- palatine process (external base view)
Maxilla
