Skin innervation is by the trigeminal nerve’s 3 branches: ophthalmic,maxillar
& mandibular nn.
Skin innervation of the face by : CN 5 ( trigeminal nerve
CN V1: ophthalmic n.
CN V2: maxillary nerve CN V^: mendibular nerve
SCALP: LAYERS
SCALP
1- Skin
2- Connective tissue (subcutis)
3- Aponeurosis (galea aponeurotica = epicranial aponeurosis)
4- Loose connective tissue:areolar space
Which contains emissary veins
5- Pericranium: Periosteum
SCALP PROPER:1+2+3
DANGEROUS AREA: because contains emissary veins
