Osteology of the Oro Cranio Facial (OCF) - Coggle Diagram
Osteology of the Oro Cranio Facial (OCF)
What are the roles of bones that form the orocraniofacial skeleton
Brain Protection: It forms the skull to safeguard the brain.
Facial Structure: Shapes our facial features.
Senses: Houses smell and vision sensory organs.
Hearing: Supports hearing structures in the temporal bones.
Jaw Function: Essential for chewing and movement.
Respiration and Smell: Aids in breathing and smell.
Articulation: Enables facial movement and speech.
Tissue Attachment: Anchors muscles and ligaments.
Facial Expression: Works with muscles for expressions and communication.
How different is the growth/formation of mandible and maxilla
Skeletal Age:
Maxilla matures earlier than the mandible.
Due to different growth patterns.
Growth Rate:
Maxilla grows rapidly in childhood.
Mandible continues slower growth into adulthood.
Facial Profile:
Maxilla shapes upper face.
Mandible influences lower face.
Growth Centers:
Both have growth centers.
Within sutures and bone sites.
Bone Formation:
Maxilla uses direct bone formation.
Mandible combines bone and cartilage.
Sites of Growth:
Maxilla grows at craniofacial sutures.
Mandible focuses on condylar heads.
Are there any structural differences between maxilla and mandible?
Location: Maxilla (upper jaw), Mandible (lower jaw).
Tooth Attachment: Maxilla (upper teeth), Mandible (lower teeth).
Mobility: Maxilla (less mobile), Mandible (highly mobile).
Number of Bones: Maxilla (two fused bones), Mandible (single bone).
Bone Thickness: Maxilla (denser), Mandible (thinner).
Functions: Maxilla (facial support), Mandible (chewing and speech).
The stages of amelogenesis and dentinogenesis in the morphogenesis process of dental crowns
Protective: Safeguard vital structures in the head and face.
Supportive: Form the framework of the face and mouth.
Functional: Responsible for specific functions like chewing and speech.
How many types of bone-shape that present on the orocranifacial skeleton
Inferior turbinal bones (2): Found in the nose, they humidify inhaled air.
Lacrimal bones (2): Protect the eyes and surround tear ducts.
Mandible: The movable lower jaw used in chewing and expression.
Maxilla (2): Form the upper jaw and eye sockets.
Nasal bones (2): Create the nose bridge and connect with other facial bones.
Palatine bones (2): Contribute to the nasal cavity and hard palate.
Vomer: Forms the lower and rear part of the nasal septum.
Zygomatic bones (2): Shape the cheeks and eye orbits.
Describe the structure and the component of Temporo Mandibular joint
Mandibular Foramen: In the mandible's ramus, it numbs lower teeth.
Mental Foramen: Near the second premolar apex, it senses lip and chin.
Alveolar Border: Upper mandible sockets secure teeth.
Ramus: Vertical, back jaw part for chewing and muscle connection.
General Structure and Classification of Articulations in the Orocraniofacial Skeleton
Orocraniofacial Skeleton: Supports vital functions.
Fibrous Joints: Sturdy connections (Sutures, Syndesmoses).
Synovial Joints: More mobile (TMJ, Hinge, Gliding).
Temporomandibular Joint (TMJ): Articular Surfaces, Discs, Ligaments, Synovial Cavity, Muscles, Blood Vessels & Nerves, Fibrous Layers.
