Brain and Spine Flashcards
Suture between frontal and parietal bones
Coronal suture
Suture between the two parietal bones
Sagittal suture
Suture between the temporal bones and the parietal bones
Squamosal suture
Suture between the occipital bones and the parietal bones
Lambdoidal suture
Junction of the coronal and sagittal sutures
Bregma
Junction of the lambdoidal and sagittal sutures
Lambda
Junction of the parietal, squamosal suture, and greater wing of the sphenoid bone
Pterion
Junction of the occipital, parietal, mastoid portion of the temporal bone
Asterion
Largest sinuses in the cheekbones
Maxillary sinuses
Sinuses in the low-center of the forehead
Frontal sinuses
Sinuses between the eyes at the nasal bridge
Ethmoid sinuses
Sinuses in bones behind the nasal cavity
Sphenoid sinuses
2 sets of bones that form the skull
Cranium
Facial Bones
8 bones that form the cranium
2 pairs of temporal bones 2 pairs of parietal bones Frontal bone Occipital bone Sphenoid bone Ethmoid bone
Bones that lie inferior to the parietal bones
2 pairs of temporal bones
Bones that are paired to form the superior and lateral walls of the cranium
2 pairs of parietal bones
Bone that forms the forehead and the superior part of the eye’s orbit
Frontal bone
Bone that forms the floor and back wall of the skull
Occipital bone
Bone that forms part of the floor of the skull, located anterior to the temporal
Sphenoid bone
Bone that lies anterior to the sphenoid, forms the roof of the nasal cavity
Ethmoid bone
14 facial bones
2 Nasal Bones-form the bridge of the nose
2 Lacrimal Bones-the medial wall of each orbit
2 Maxillary Bones-forms the upper jaw
2 Zygomatic Bones-commonly referred to as the cheek bones
2 Palatine Bones-form the posterior part of the hard palate
2 Inferior Nasal Conchae-extend inferiorly from the lateral walls of the nasal cavity
Vomer-contributes to the nasal septum
Mandible-forms the lower jaw
