Mandible Flashcards
TMJ
between the condyle of the mandible & the squamous portion of the temporal bone.
Only movable bone in the skull
Mandible
Densest & largest facial bone
Mandible
Contains mental foramina
Mandible
Mandibular symphysis
2 halves fuse after birth
Mental protuberance
protuberance at lower portion of symphysis
Alveolar process/ridge
spongy ridge of bone with sockets for teeth
body is in a - position
Horizontal
Ramus is
posterior vertical position
Angle of Mandible connects
vertical and horizontal parts
Angle of Mandible corresponds to the
gonion
Coronoid process extends - and - from -
anterior and superior from ramus
Does coronoid have an articulation?
no
Coronoid process serves as a
muscle attachment
Mandibular notch
deep notch between condyloid and coronoid process.
Mental foramen
: small opening on outer surface of body
Mental foramen is a passage for
mandibular nerve
Mandibular foramen
opening on inner side of the ramus for mandibular nerve
Hyoid bone is located
base of tongue
Hyoid bone is held in position by
stylohyoid ligaments
Stylohyoid ligaments
ligaments extending from styloid process of temporal bone
Only bone in body that does not articulate with any other bone
Hyoid
Hyoid bone is divided into
body, two greater cornua and two lesser cornua
Hyoid bone division serves as a
attachment for certain muscles of the larynx and tongue
Is hyoid bone part of the skull?
No
Hyoid bone lies - to mandible and in -
inferior to mandible, in anterior neck
Hyoid is an attachment point for
neck muscles that raise and lower larynx during swallowing and speech
success of the SMV projection cranial base depends on
IOML as parallel to IR as possible CR perp to IOML
SMV CR directed thru
Sella turcica
SMV CR passes thru
3/4 in ant to level of EAM
Mandibular Rami – perp to IR
OML
Mandibular Rami CR
perp to exit acanthion
Mandibular Rami PA used to r/o
medial or lateral displacement of fragments in fractures of rami
PA axial mandibular rami angle
