Lesson 05 (SKULL) Flashcards
It consists in cranial part (braincase) also most complex part of skeleton
50 bones
Skull
Three types of skull
Brachycephalic
Mesatiphalic
Dolichocephalic
What do you call if the dog is underbite?
Prognathia
What do you call if the dog is overbite?
Brachianathia
It composed of 2 halves by cartilaginous called Mandibular symphysis
Mandible
It carries the socket or aveoli for teeth of the lower jow
Mandibular symphysis
It gives intervention in your blood
Mental foramen
It drains blood to the inferior dental arcade
Mandibular vein
Most caudal bone of the skull. Contains foramen Magnum, which spinal cord passes
Occipital bone
What are the PAIRED bones in cranial part (brain case)?
-occipital bone
- parietal bone
- Frontal bone
- Temporal bone
What are the UNPAIRED bones in cranial part (brain case)?
Ethmoid bone
Sphenoid bone
It is together with the frontal bone also forms the roof of the cranial cavity
Parietal bone
It forms the rostral part of the roof of the cranial cavity?
Frontal bone
It lies below the parietal bone also most ventral part of the bone forms around with prominence called tympanic bulla
Temporal bone
Unpaired bone, the wall of the cranial cavity
Ethmoid bone
It is unpaired bone lying on the ventral aspect of the skull. Also houses the PITUARY GLAND by depression called SELLA TURCICA
Sphenoid bone
What are the bones in the facial part?
Pterygoid bone
Vomer
Incisive bone (premaxilla)
Nasal bone
Maxilla bone(upper jaw)
Lacrimal bone (prefrontal bone)
Zygomatic bone (jugular, malar)
Palatine bone
Zygomatic arch
It forms the part of the Lateral wall of passageway to the soft palate
Pterygoid bone
It is a GUTTER SHAPED bone that long longitudinally separates the right and left of nasal passages
Vomer (plowshare bone)
It supports the upper incisor and contributes the formation of Palatine fissure. most RORTRAL bone in skull
Incisive bone (premaxilla)
It is longitudinal bone forming the roof of nasal cavity
Nasal bone
It forms the first osseos lateral walls of the major part of the hard palate
Maxilla bone (upper jawbone)
It lies at the medial surface of the orbit, which houses the eyes
Lacrimal bone (prefrontal bone)
It is an arch of bone that projects laterally from the skull forming the cheek bone
Zygomatic bone (jugal, malar)
it forms part of the hard pallet, along with the maxilla and incisive bone
Palatine bone
Bony arch forming the lateral wall all of the orbit. The process of the zygomatic bone and zygomatic process
Zygomatic arch
It is a horizontal part bearing the lower incisor, canine, premolar and molar teeth
Body
It is vertical part bearing no teeth
Ramus
It is the physiologic gap between the incisors and cheek teeth
Diastema
What is the treatment if the synthesis in the mandible got broken?
Cerclage
It is drilling of holes into paranasal sinuses. May used to drain infections in sinuses
Trephination
It lies in the intermandibular space and consists of fine bones and cartilages.
Hyoid apparatus
What are the parts of hyoid apparatus?
Stylohyoid
Epihyoid
Ceratohyoid
Basihyoid
Thyrohyoid
This type of hyoid articulates rostrally with the epihyoid; it is the largest and often called GREAT CORNUA
Stylohyoid
Small round with bones situated between the stylohyoid and ceratohyoid; aka the MIDDLE CORNUA
Epihyoid
It is in between the epihyoid and basihyoid; aka the SMALL CORNUA
Ceratohyoid
It articulate caudally with the rostral cornua of the thyroid cartilage of the layrnx
Thyrohyoid
