RA Test 2 Flashcards
the oriface in the face bounded by the margins if the nasal bones and the maxilla gives you the “angle of projection”
Nasal Cavity
the bones that lie directly inferior to the glabella; forms the brige of the nose and the dome over the superior portion of the nasal cavity
Nasal Bones (2)
the diamond shaped bones that form the cheekbones, located on the frontal and lateral planes of the face, the bones form part of the inferior and lateral surfaces of the orbital cavity
“zygomatic process”
“process of the temporal bone”
Zygomatic Bones (2)
bones of the upper jaw, forms that skeletal base for the most of the superior portion of the face, anterior roof of the mouth, sides and floor of the nasal cavity, and floors of the orbits
Maxilla (2)
the sharp bony projection located medially at the inferior margin of the nasal cavity covered by the columna nasai (seperates the two nostils)
Nasal Spine
the skin that covers the nasal spine
Columna Nasai
a bony ridge found on the inferior surface of the Maxilla and the superior surface of the Mandible which contains the sockets for the teeth
Aveolar Process
the ascending part of the upper jaw, gradually protrudes as it rises to meet the frontal bone
Frontal Process of the Maxilla
the front portion of the roof of the mouth
Palatine Process
protuberance of teeth; “buck teeth
Dental Prognathism
the horseshoe shaped bone forming the lower jaw consist of the body and the ramus
Mandible (1)
the curve shaped, horizontal, and lowest part of the lower jaw, contains the alveolar processes for the teeth, as the maxilla does
Body
the trianglular projection on the inferior portion of the anterior mandible; creates the anterior projection of the chin
Mental eminence of the Mandible
the depression between the mental eminence and the inferior incisor teeth
incisive fossa
a bony ridge found on the inferior surface of the Maxilla and the superior surface of the Mandible which contains the sockets for the teeth
alveolar processes
the vertical portions of the mandible it is the wide, flat, and quadrilateral in shape
ramus
a rounded prominence at the end of a bone forming an articulation; the posterior process of the ramus of the mandible
Condyle
the anterior, non-articulating process of the ramus of the mandible which serves as the insertion for the temporalis muscle
Coronoid Process
the depression that is located between the condyle and the coronoid process
Mandibular Notch
the widest part of the head
Bi-Parietal
the widest part of the face
Bi- Zygomatic
the widest part of the jaw
Bi- Mandibular
the bone of the nasal cavity situated between the nasal passages on the median plane; it forms the inferior and posterior portion of the septum of the nose
Vomer Bone
one of the bones forming the posterior part of the hard palate and lateral nasal wall between the interior pterygoid plate of the sphenoid bone and the maxilla
Palantine Bones
bones that hold the eyeballs
Lacrimal Bones
the point of muscle attachment which moves the least; the beginning of muscle contraction
Origin
the point of muscle attachment which moves the most
Insertion
Known as “EPICRANIUS”: this is a broad muscle covers the top of the skull, it consists of two parts, the occipitalis, and the frontal bone.
Occipitofrontalis Muscle (1)
draws the scalp posteriorly and anteriorly, causing the eyebrows to raise and wrinkles the form on the forehead
Occipitofrontalis muscle
when contracted it raises the eyebrows; continual contraction forms Transverse Frontal Sulci (wrinkles that run across the forehead; aquired facial marking)
Occipitofrontalis muscle
a broad fan shaped muscle arising in the temporal cavity and inserting on the mandible (goes upward)
Temporalis Muscles (2)
Function: a muscle of mastication and is the strongest chewing muscle; it closes the mandible, and assists in side to side movement of the mandible
The Temporalis Muscles (2)
EFFECTS ON SURFACE FORM: this muscle provides some bulk to the temporal cavity
The Temporalis Muscles (2)
a muscle arising from the zygomatic arch and inserting in the mandible (goes downward)
The Masseter Muscles (2)
FUNCTION: a muscle of mastication that closes the mandible; the weaker of the two
The Masseter Muscles (2)
EFFECTS ON SURFACE FORM: this muscle provides bulk to the side of the cheek area
The Masseter Muscles (2)
