Scalp proper
What is scap proper
skin
dense connective tissue
aponeurosis
What is the innervation of the scalp and vasculature contained within the scalp
loose connective tissue
What is the function of the dense connective tissue
anchors skin to aponeurosis
What arteries are found within the connective tissue layer of the scalp
external carotid and ophthalmic arteries
What are the external carotid artery branches within the scalp
superficial temporal
posterior auricular
occipital
What nerves supply GSA innervation to the scalp
branches from CNV, C2, and C3
What divides cranial innervation from cervical innervation in the scalp
vertex
GSA innervation from CN V is where on the head
face and sides
GSA innervation from C2 and C3 is where on the head
back of head
What is the sensory innervation of the auriculotemporal nerve
Innervates temple and side and side of scalp
What muscle is contained within the aponeurosis of the scalp
occipitofrontalis muscle
What is the aponeurotic tendon between frontal and occipital bellies
galea aponeurotica
What is the occipitofrontalis muscle innervated by
CN7
What layer will infections spread through in the scalp
loose CT; danger level, more room for things to spread and grow
What pharyngeal arch will give rise to the face

What nerve is associated with first pharyngeal arch
cranial nerve V
WHat nerve will supply cutaneous innervation to the face.
Trigeminal nerve
What will CN V1 supply to the face
forehead, upper eyelids, tip of nose
What will CN V2 supply to the face
cheeks, lateral nose, upper lip
What will CN V3 supply to the face
chin, lower lip, temple
Where are the cell bodies found that provide sensory innervation to the face
trigeminal ganglion
What are possible cause of trigeminal neuralgia
abberant artery that compresses cranial nerve 5
What are possible treatment options for trigeminal neuralgia
carbamazepine to treat symptoms; microvascular decomphression
What are the muscles of facial expression
