all the sutures
1-cranial 2-sagittal 3-lambdoid 4-squamous 5-petrion (parieto sphenoidal) 6-astrion(parietotemporal) 7-temporosphenoidal 8-frontosphenoidal
petrion
between sphenoid - temporal-parietal -frontal
so weak- can be damaged easily
ant. branch of middle meningeal
ant. branch of middle meningeal
the most important to feed meninges
basiocranium - sup. view
frontal occipital etemoid sphenoid temporal
layers of skull cap
outer table
diploe
inner table
diploe veins
placed inside diploe
sinuses’ type
1-paranasal sinuses
2-venous sinuses
paranasal sinuses
1-frontal 2-ethemoid 3-maxilla * biggest 4-sphenoid function ( 1- lightening the skull 2 - voice resonance )
the oddest paranasal sinus?
ethemoid which is consisted of 3 parts (1-ant. 2-mid. 3 -post.)
whats inside paranasal sinuses?
endodermal epithelial which secrete mucus
nasal meatuses ?
sup . mid. and inf.
sinuses drain into sup. and middle
the place of frontal sinus ?
the roof of orbit fossa
maxillary sinuses’ place?
floor of orbit fossa
sphenoid sinus?
sup . and post. to nasal cavity
why sinusitis ?
inflammation- allergy
why sinusitis hurt ?
the mucus of sinuses have receptors
facial landmarks?
outer conthus infraorbital margin acanthion nasion mental point glabella gonion supercilliary arch interpupillary line supraorbital groove
facial lines?
glabelomeatal line infraorbitomeatal line acanthiomeatal line orbitomeatal line mentomeatal line
nasion
frontal to nasal bones
reid’s base line- frankfurter line - anthropological base line
infraorbitomeatal line
why knowing landmarks?
radiology - anthropology - surgery and ….
the sensory nerve of face?
nerve V - or trigeminal
ophtalmic sensation?
vertex to upper eyelid
maxillary nerve -infraorbital nerve
lower eyelid to upper lip
mandibular
lower lip to chin
trigeminal nerve
ophtalmic –> supraorbital - supratrochlear - infratrochlear -only sensory-
maxillary –> infraorbital-zygomatico temporal-only sensory-
mandibular–>mental - auriculotemporal-bucchal-palatine
parotid’s skin innervation
spinal nerve
frontal bone’s parts
squamous - orbital surface
supercilliary arch?
eyebrows are on it
frontal bone’s processes
zygomatic process
maxillary process
what’s nasion ?
the joint between nasal bone and frontal bone
temporal line on frontal bone?
starts from zygomatic process
temporal lines?
sup. temporal line –>fascia
inf. temporal line –> muscle
on parietal bone
digital impression?
on frontal bone
the roof of orbit?
lesser wing of sphenoid
frontal bone
ethemoid
the foramen on ethemoid bone?
caecum foramen.
emmissary veins
the part between 2 parts of frontal…?
frontal crest
what can be seen from superior point of ethemoid?
cribriform surface and plate and also crista gali
where is ethemoid placed?
in the nutch between 2 parts of frontal bone.named –>ethemoidal nutch
what are digital impressions ?
the place for brain chins and because our finger tip can fill that it is called the digital impression
piriform foramen?
anterior nasal aprature
alveolar process ?
maxilla and manibul
teeth ?
4 incisors -2 anines - 4 premolars -6morals
hard palate …
palatine surface of maxilla + palatine bone
pyramid process
2 great palatine foramen
incisive foramen
hard palatine artery and nerve
greater palatine artery from greater palatine foramen to incisor foramen
greater palatine nerve + nasopalatine nerve
nasopalatine nerve innervation …
is a sensory nerve
innervates both nose and the roof of oral cavity and the sense of the frontal teeth
what passes through greater palatine foramen ?
greater palatine nerve and artery
the lesser palatine artery passes through what ?
it passes through pyramid process
groove for greater palatine artery
located on the palatine surface of maxilla
is there any fossa on maxilla ?
yes , canin fossa whih is the origin of levator anguli oris
joints of maxilla bone
nasal - lacrimal -zygoma -palatine
the place for lacrimal crest …
both on maxilla and lacrimal bones
why do we have lacrimal fossa?
it is the place for lacrimal bag
mandibule . . .
ramus - body
body involves alveolar processes and also mental protuberance -mental foramina
ramus involves condyle and cronoid processes
difference between condyle and coronoid processes
coronoid process is not attached to any bones
but condyle makes the temporomandibular joint
the space between external acustic meatus and chondyle ?
auriculotemporal nerve from mandibule
and also superficial temporal artery from carotid artery
what passes superficial to mandibular nutch?
nerve and artery to massetter muscle
oblique line ?
on mandibule
and attaches to depressor muscles of the lips
what can be detected from the inside of the mandibule bone?
lingula mylohyoid line and groove mandibular foramen pterygoid fovea sub mandibular and sublingual fossi
what attaches to pterygoid fovea ?
pterygoid lateralis
say everything about mandibular canal?
starts from mandibular foramen and ends to mental foramen
inferior alveolar nerve from mandibular nerve passes through it
and it innervated the lower teeth
and when it comes out it changes to mental nerve
another branch of it passes through mylohyoid groove and innervates this muscle
what attaches to lingula ?
sphenomandibular lig.
2 other branches of maxillary nerve
zygomaticofacial and zygomatico temporal
does sphenoid have spine?
ofcourse
nerve in nose…
ant. ethemoidal and it’s branch passes through ethemoidal groove and changes to external nasal
the origin is olfactory nerves
