Anatomy : Head And Correlates Flashcards
Fracture that passes through maxillary sinuses, infraorbital foramina, bridge of the nose
Le fort II
Fracture that passes through the superior orbital fissure, ehmoud and nasal bonrs, greater wing of sphenoid an frontozygimatic sutures
Le fort III
Why is the facial nerve at risk of injury during forceps delivery?
Absence of the mastoid process at birth
Order of obliteration of sutures
Bregma – sagittal – coronal – lambdoid
Premature closure of sagittal suture
Scaphoncephaly
Premature closure of coronal or lambdoid suture on one side
Plagiocephaly
Premature closure of coronal sutures bilaterally
Oxycephaly or turricephaly
Muscle giving rise to aponeuroses of scalp going from forehead to occiput
Occipitofrontalis
Layers of the scalp
Skin Connective tx, dense Aponeurosis Loose connective tx Peicranium
Muscle giving rise to aponeuroses of scalp going from either temporal bones
Temporoparietalid and superior auricular muscle
Innervation of the scalp aponeurosis
Facial nerve
Layer of he scalp which is highly vascularized
Dense conndctive tissue layer
Fracture that passes through maxillary alveolar process
Le fort 1
Terminal branches of the facial nerve
Temporal Zygomatic Bucxal Marginal mandibular Cervical
Danger area of the scalp
Loose connective tissue
Because of emissary veins through which infection could pass into the cranial cavity
