- subraorbital foramen
- supraoribtal artery and nerve pass to the forehead
- superorbital fissure
- cranial nerves to eyes
- optic canal
- allows optic nerves to pass to eyes
- Bone that supports the cerebellum
- Occipital bone
- Sagittal suture
- fuses parietal bone down cranial midline
- Coronal suture
- fuses parietal bone and frontal bone
- Lambdoid suture
- fuses parietal bone and occipital bone
- Squamous suture
- fuses parietal and temporal bone
- Mastoid process
- connection for neck muscles
- occupital condyle
- head nodding
- foramen magnum
- where the brain connects to the spinal cord
- stylomastoid foramen
- allows cranial nerve VII (facial nerve) to leave the skull
- Styloid process
- odd looking that comes to a point attachment point for tongue and neck muscles also ligament attachment for hyoid bone
- foramen lacerum
- closed off by cartilage in a living person
- cartoid canal
- cartoid arteries enter skull
- external acoustic meatus
- sound enters styloidmastoid foramen
- jugular foramen
- jugular vein and 3 cranial nerves
- cornoid process
- large temporlis muscle attaches to elevate mandible
- body of mandible
- anchors lower teeth
- mandibular foramen
- nerve for teeth sensation, dentist inject for numbing
- mental foramen
- blood vessels and nerves ogf chin
- alveolar margin
- teeth sockets
- zygomatic process
- where zygomtic bone connects with maxilla, cheek bones
- infraorbital foramen
- maxillary nerve (cranial nerve V) and artries pass through face
- paranasal sinuses
- 5 bones, frontal, sphenioid, enthmoid, and a pair of maxillary bones. - consists of mucus linging in air filled sacs that filter debris that travels into nasal passage -alters voice resonance
- hyoid bone
- only bone not directly connected to another bone. -lies inferior to mandible -anchored to styloid process by ligaments -involved in tongue movement, neck muscles, and moving larynx
- herniated disc
- nucleus protrodes through an anulus
- atlas
- no body or spinous process -nod "yes"
- superior articular facet
- hold the occipital condyles of the skull
- axis
- unlike atlas, see a spinous process. -helps say no -if missing part of axis, fuses with atlas during embryonic development
- Cervical vertebrae
- support skull and make up neck
- Thoracic vertebrae
- support upper and middle back
- Lumbar vertebrae
- support majority of the weight of the body and its stress
