Skull Anatomy Flashcards
Name the three main areas of the skull
Cranium face jaw
Frontal bone
At the front of the cranium above the eyes forming the forehead
Parietal bone
Pair of plates forming the top and great area with the sides of the cranium
Temporal bone
Pair of fan shaped plates in the temporal region on the lower side of the cranium in front of the ears
Occipital bone
At the back underside of the cranium
Sphenoid bone
Single plate forming the majority of the base underside of the cranium
Ethmoid bone
Single plate at the front bay section of the cranium immediately behind the nose
Sutures
Immovable joints of The skull
Atlas
The topmost vertebrae used for nodding
Axes
The second bone turning left to right
Foramina
Bony openings for passage of vessels and nerves
Cancellous spongy bone
Where vessels and nerves run through
Fontanella
Membrane covered spaces in the skull at birth, allow brain to grow. This slowly close by 18 months old
Coronoid sutures
Where bony plates meet together
Fissures
Where nerve cells run through natural spaces between adjacent bones
Bony projections
The attachments for ligaments and muscles
How many bones in the face are there
11
Vomer
Single bone behind the nasal cavity that connects the cranial and facial regions of the skull together
Lacrimal bones
Fragile bones forming the inner wall of the orbital cavity
Nasal bones
Pair of bones forming the bridge of the nose
Nasal turbinates
Pair of fragile cold bones projecting into the nasal cavity increasing the contact of inspired air separated by the midline of the nasal septum
Zygomatic bones
A pair of facial bones that articulate posteriorly and extended anteriorly into the zygomatic archThe cheekbone
The jaw
Maxilla
Pair of bones forming the aperture the lower border of the orbital cavities and the base of the nose also the anterior portion of the hard palate
The mandible
A single horseshoe shaped bone forming the lower jaw with a vertical posterior bony structure articulating with the cranium at the temperomandibular joint
Oroantral fistula
Where unwonted connection is created between the mouse and the Antrim during the extraction of upper molar and second premolar teeth
Into maxillary suture
Where the two maxillary bone is joined together
Maxillary turborosity
The small bone at the very back of the palate that can be fractured off during third molar extraction
Intraorbital foraman
Beneath the eyesockets
Nerves supplying upper teeth and labial soft tissue
Greater and lesser Palatine foramina
Back of the hard palate
Upper posterior teeth and palatal soft tissue
Incisive foreman
Front centre of hard palate
Palatal soft tissue upper anterior teeth
Mental synthesis
Where the two bones of the mandible Join together at the Central line
The horizontal section of the mandible is called
The body of the mandible
The vertical section of the mandible is called
The Ramas of the mandible
What is the joint called that allows for opening and closing of the mouth
Temporary mandibular joint TMJ
Mylohyoid ridge
Whether mylohyoid muscle attaches to from the floor of the mouth inside the mandible
External oblique ridge
Masks the base of the Alviola processes
Coronoid process
The front edge of the Ramas. The dip between called sigmoid notch
When the mouth is closed to coronoid process slots under the zygoMatic arch of the face
Mandibular foremen
Protected by the lingula
Lower teeth and some soft tissue where it enters the mandibular
Mental foramen
Where premolars are, this is where the nerve exits
