Week 3 - Bones

condyle

a rounded prominence at the end of a bone forming an articulation

glabella

a single bony prominence of the frontal bone located between the superciliary arches in the inferior part of the frontal bone above the root of the nose

mental eminence

a triangular projection on the inferior portion of the anterior mandible

foramen magnum

an opening in the occipital bone through which the spinal cord passes from the brain

coronoid process

anterior, non-articulating process of the ramus of the mandible which serves as the insertion for the temporalis muscle

frontal process of the maxilla

ascending part of the upper jaw which gradually protrudes as it rises beside the nasal bone to meet the frontal bone

mandible

bone forming inferior jaw

alveolar processes

bony ridge found on the inferior surface of the maxilla and the superior surface of the mandible which contains the sockets for the teeth

parietal eminences

determine the widest part of cranium

zygomatic arch

determine the widest part of the face

maxilla

form the skeletal base of the most superior face, roof of the mouth, sides of the nasal cavity, and floor of the orbit

angle of mandible

formed by the junction of the posterior edge of the ramus of the mandible and the inferior surface of the body of the mandible; marks the widest part of the lower 1/3 of the face

body

horizontal portion of the lower jaw

crown and vertex

horizontal surface of the frontal bone

superciliary arches

inferior part of the forehead just superior to the median ends of the eyebrows

nasal bones

lie directly inferior to the glabella forming a dome over the superior portion of the nasal cavity

frontal eminences

paired, rounded, unmargined prominences of the frontal bone found approximately one inch beneath the normal hairline

external auditory meatus

passageway of the ear

temporal bones

represent the inferior portion of the sides and base of the cranium, inferior to the parietal bones and anterior to the occipital bone

zygomatic bones

represent the widest part of the cheek

mastoid process

rounded projection on the inferior portion of the temporal bones just posterior to the lobe of the ear, they help to locate the posterior lobe of the ear

mandibular fossa

small oval depression on the zygomatic process of the temporal bone into which the condyle of the mandible articulates, just anterior to the external auditory meatus

supraorbital margins

superior rim of the eye sockets

frontal bone

the anterior 1/3 of the cranium, forming the forehead and the anterior portion of the roof of the skull

occipital bone

the lowest part of the back and base of the cranium

nasal spine of maxilla

the sharp bony projection located medially at the inferior margin of the nasal cavity

squama

the vertical surface of the temporal bone

parietal bones

two bones of the skull that form the roof and part of the sides and back of the skull

forehead

vertical surface of the frontal bone

ramus

vetical potion of the mandible
