🗑
|
||||
| nasal bones | 2 R+L small oblong bones that meet in the midline to form the bridge of the nose. each joins the frontal bone at the nasofrontal suture called the nasion. articulate with the frontal ethmoid and maxillary bones
🗑
|
||||
| maxillary bones | 2 R+L unite in the midline in early life. articulate with all other facial bones except the madible
🗑
|
||||
| body of maxilla | lateral to the nose forming the foundation of the cheek and the floor of the orbit and part of the roof of the mouth
🗑
|
||||
| maxillary sinuses | largest paranasal sinuses. triangular shaped cavities aka antrum--empty into the nasal cavity
🗑
|
||||
| infraorbital foramina | immediately bleow the orbital cavity allow for the passage of blood vessels and nerves to the soft tissue of the cheek
🗑
|
||||
| nasal spine | a small bony projection found at the base of the nose formed by union of two maxillae
🗑
|
||||
| frontal process | extends superiorly from the body just lateral to the nose and medial to the orbital cavity it articulates with the frontal bone
🗑
|
||||
| zygomatic process | extends laterally from the body to articulate with the zygomatic bone
🗑
|
||||
| alveolar process | extends from the body to form the sockets for the teeth
🗑
|
||||
| palatine process | flat shelf of bone that forms the anterior 3/4 o fth ehard palate separates nasal cavity from the oral cavity
🗑
|
||||
| zygomatic bones | 2 R+L form the most prominent portion of the cheek and lateral portion of the orbi
🗑
|
||||
| body of zygoma | small central portion
🗑
|
||||
| frontal process of zygoma | extends upward from the body forming the lateral margin of the orbital cavity articulates with the frontal bone
🗑
|
||||
| maxillary process of zygoma | extends medially from the body to join with the maxilla
🗑
|
||||
| temporal process of zygoma | extends posteriorly to join with the zygomatic process of the temporal bone to form the zygomatic arch
🗑
|
||||
| lacrimal bones | 2 R+L thin bones located in the medial and inferior portion of the orbit
🗑
|
||||
| lacrimal groove | lacrimal duct passes through so teas can be carried to nasal cavity
🗑
|
||||
| Palatine bones | 2 R+L they help to form the hard palate and the lateral walls of the nasal cavity. L shaped The horizontal portion of each bone meets at the midline to form the posterior 1/4 of the hard palate
🗑
|
||||
| vomer | lies vertically in the midline of the nasal cavity. joins with the perpendicular plate of the ethmoid to form the nasal septum. vomer rests on the hard palate
🗑
|
||||
| palatine bones | 2, R+L, Lshaped bones they help to form the hard palate and the lateral walls of the nasal cavity. The horizontal portion of each bone metts at the midline to form the posterior 1/4 of the hard palate.
🗑
|
||||
| Inferior nasal conchae | 2 R+L thin curled plates of bone extending from the later wall of the nasal cavity. Not part of the ethmoid like the superior and middle nasal conchae
🗑
|
||||
| Mandible | Single bone of lower jaw. Only moveable bone in the face. Has a horizontal portion, body and two vertical portions--rami
🗑
|
||||
| Mandibular angle | 2 r +L, rounded areas formed by the union of the body and ramus on each side. radiographic landmark--gonion
🗑
|
||||
| mandibular body | the horizontal portion extending from angle to angle
🗑
|
||||
| mandibular symphysis | faint vertical ridge in the midline anteriorly where the two halves of the mandible fused prior to birth.
🗑
|
||||
| mental protuberance | the chin
🗑
|
||||
| mental foramina | small openings on each side of the midline allowing for the passage of the mental branch of the mandibular nerve to reach the lower face
🗑
|
||||
| alveolar process of mandible | on the upper margin of the body with 16 sockets for the lower teeth.
🗑
|
||||
| ramus of mandible | 2 R+L, vertical extensions on each side
🗑
|
||||
| coronoid process | Thin flat anterior process on the superior aspect of the ramus. Attatchment point for facial muscles
🗑
