The Skull Flashcards
what is the skull divided into
- Neurocranium
- viscerocranium
How many bones are in the neurocranium
8
How many bones are in the viscerocranium
14
what are the bones in the neurocranium
- frontal
- temporal (2)
- occipital
- sphenoid (2)
- parietal
- ethmoid
what are the bones in the viscerocranium
- zygomatic (2)
- maxialla (2)
- mandible
- lacrimal (2)
- nasal (2)
- inferiror nasal concha (2)
- vomer
- palatine (2)
what does the neurocranium cover
this is the bony case of the brain and its membranous coverings, the meninges, most of the neurocranial bones are flat or have substantial flat portions that contribute to the body case of the Brain
what does the facial skeleton (viscerocranium) cover
facial skeleton from the anterior part of the cranium and consists of bones that surround the orbits, nasal cavity and mouth
what separates the frontal and parietal bone
the sagittal suture
what separates the parietal bone from the occipital bone
the lambboid suture
what does the zygomatic arch consist of
the maxilla and the temporal bone
what is the temporomandibular joint
this is where the mandible articulates with the skull at the temporal bone
the sphenoid bone articualtes with
all the cranial bones
- the frontal
- the parietal
- the occipital
- temporal bones
what makes up the hard plate (roof of mouth)
the palatine bone
what does the zygomatic bone articulate with
- maxilla
- temporal
- sphenoid
- frontal
what are the 3 fossa
- anterior cranial fossa
- middle cranial fossa
- posterior cranial fossa
