Lecture 4 Flashcards
Name two regions of skull
Cranium (brain case)
Facial bones
Name the eight cranial bones (neurocranium)
two parietal
two temporal
frontal
occipital
sphenoid
ethmoid
cranial bones are thin yet remarkably strong for their weight
The four sutures of the parietal bones
Coronal
Saggital
Lamboid
Squamosal
Occipital bone’s major markings
what happens at the foramen magnum
brain stem turns into spinal cord
Name four regions of the temporal bones
squamous
tympanic
mastoid
petrous
Major markings on temporal bones
zygomatic, styloid and mastoid processes
mandibular and middle cranial fossae
Major openings of temporal bones
Stylomastoid and jugular foramina
External and internal auditory meatuses
Carotid canal
Four zones of sphenoid bone
central body
greater wings
lesser wings
pterygoid process
Major markings of sphenoid bone
Sella turcica, “turkish saddle” (pituitary gland sits here)
Pterygoid process
Major openings of Sphenoid bones
Foramen rotundum
Foramen ovale
Foramen spinosum
Optic canal
Superior orbital fissure
Ethmoid bone major markings
cribriform plate
crista galli
perpendicular plate
nasal conchae
ethmoid sinuses
Mandible’s markings
Coronoid process
Mandibular condyle
Alveolar margin
Mandibular foramina
Mental foramina
what are the keystone bones of the facial region?
Maxillary bones
Major markings of maxilary bones
Palatine process
Frontal process
Zygomatic process
Alveolar margins
What do the zygomatic bones make?
cheeks
What makes the bridg of the nose?
nasal bones
What are the walls associateed with tears?
