Axial Bone of the Skull Flashcards
consist of the cranial part (braincase), which surrounds the brain, and the facial part.
Skull
the most caudal bone of the skull
occipital bone
together with the frontal bone, it forms the roof of the cranial cavity
Parietal Bone
forms the rostral part of the roof of the cranial cavity
Frontal bone
lies below the parietal bone on the caudolateral surface of the skull
temporal bone
lThe most ventral part of the temporal bone forms a rounded prominence
called the _______________
tympanic bulla
houses the structures of the middle ear.
tympanic bulla
forms the rostral wall of the cranial cavity.
Ethmoid Bone
unpaired bone, lying on the ventral aspect of the skull, forming the floor of the cranial cavity.
Sphenoid Bone
Sphenoid bone houses the pituitary gland via a depression called __________.
sella turcica
forms part of the lateral wall of the air passageway dorsal to the soft palate
Pterygoid Bone
- gutter-shaped bone that longitudinally
separates the right and left nasal passages.
Vomer (Plowshare Bone)
supports the upper incisors and contributes to the formation of palatine fissure. Most rostral bone of the skull
Incisive Bone (Premaxilla)
longitudinal bone forming the roof of nasal cavity.
Nasal Bone
forms the osseous lateral walls of the
face and major part of the hard palate
MAXILLA BONE (upper jawbone)
lies at the medial surface of the orbit,
which houses the eye.
LACRIMAL BONE (prefrontal bone)
the zygomatic arch is an arch of bone
that projects laterally from the skull, forming the cheekbone.
ZYGOMATIC BONE (Jugal, malar)
forms part of the hard palate, along with the maxilla and
incisive bone.
PALATINE BONE
the bony arch forming the lateral wall of the orbit.
Zygomatic Arch
carries the sockets or alveoli for the teeth of the lower jaw.
Mandible
horizontal part bearing the lower incisor, canine, premolar and molar teeth
body
vertical part bearing no teeth
Ramus
the physiologic gap between the incisors and cheek teeth
Diastema
the mandible is composed of two halves or dentaries, joined at the chin by a
cartilaginous joint called the _________________
mandibular symphysis
