skull face and scalp Flashcards
the viscerocranium protects
facial bones to protect airway
the importance of the pteryon
easily broken because middle meningeal artery is there
foramen that line up on the skull
mental, supraorbital, infraoribital
bones of the face
nasal (2) Maxilla (2) Zygomatic (2) Mandible Lacrimal (2) Vomer Inferior nasal conchae (2) Palatine (2)
teeth processes for maxilla and mandible
alveolar processes
foramen of the mandible
mental foramen
foramen of the maxillae
infraorbital foramina
the valley between the condyl and the coronoid process of the mandible
mandibular notch
opening on the infernal surface of the ramus of the mandible
mandibular foramen
what passes through the mandibular foramen
mandibular nerve and b.v.
the grove that appears after the mandibular foramen
mylohyoid groove
a small projection of bone on the posterior aspec of the mandible in the midline for attachment of the geniohyoid and genioglossus
mental spine
boundries of the orbit
Frontal bone- roof zygonmatic bone- lat wall maxilla - floor and part of medial wall lacrimal and ethmoid - medial wall sphenoid- posterior wall
where is the supraoribital foramen
in the superciliary arch
where is the optic canal
in the medial wall
where is the superior orbital fissure
in the medial wall
where is the inferior orbital fissure
in the floor
the lacrimal groove communicates with what
the nasal cavity
projection of the lat wall of the nasal cavity
nasal conchae
what bone has the superior nasal conchae
ethmoid
what bone has the middle nasal conchae
ethmoid
what bone has the inferior nasal conchae
separate bones
role of the paranasal sinuses
bone lightening
resonance to voice
what lines paranasal sinuses
mucousal membranes
what are the paranasal sinuses continuous with
nasal cavity
paranasal sinuses
frontal
ethmoid air cells
sphenoid
mmaxillary
amount of ethmoid paranasl sinuses
3-14
what nerve does the cribiform plate transmit
olfactory nerve (CNI)
what does the optic canal transmit
optic Nerve (CN II), ophthalmic a
what does the superior orbital fissure transmit
CN III, CN IV, CN VI, ophthalmic (CN V1)
what does the foramen rotundum transmit
maxillary n (CN V2)
what does the foramen ovale transmit
mandibular n (CN V3)
what does the foramen spinosum transmit
middle meningeal a
what does the foramen lacerum transmit
infernal carotid a
what does the jugular foramen transmit
internal jugular vein, CN IX, CN X, CN XI
what does the internal acoustic foramen transmit
CN VII, CN VIII
what does the stylomastoid foramen transmit
CN VII
what does the hypoglossal canal transmit
CN XII
what does foramen magnum transmit
Vertebral arteries, spinal cord and CN XI
what does the carotid canal transmit
internal carotid a
Scalp covers from
supraorbital rim of eye to external occipital protuberance
layers of the scalp
skin connective tissue (Dense) aponerotic layer loose connective pericranium
what fills the dense connective tissue layer of the scalp
nerves and vessels
a superficial wound to the dense connective tissue layer of scalp leads to
high bleeding that can cause death
deep wounds to apponeurosis layer leads to
a large gape
superfical temporal artery branches from
external carotid
posterior auricular artery branches from
external carotid
occiptial artery branches from
external carotid
supratrochlear and supraorbital branches from
opthalmic artery through the eye (branch of internal carotid
the danger space of the scalp
loose areolar tissue
