2. Structure
Part of Head.
Extend from Superciliary arches
anterior, to superior nauchal lines
posterior.
Made of 5 Layers
3.
4. Layers of SCALP
Skin
Connective Tissue (Deep)
Apo neurosis
Connective Tissue (Loose)
Periosteum
5.
6. Muscles of SCALP
Occipitofrontalis
Origin
• Occipital Process
– Superior Nauchal Line
• Frontal Process
– Superciliary Arches
Insertion
• Both are Inserted in Epicranial Eponeurosis
Nerve Supply
• Facial Nerve
Function
• Move Scalp
• Raise Eyebrows
8. Innervations of SCALP
SCALP is inerveted in two portions.
Part of Scalp Anterior to Ear & Vertex of
Skull.
Part of Scalp Posterior to Ear & Vertex of
Skull
9. Innervations of Part of SCALP anterior to
Ear & Vertex of Skull
Innervated by Branches of Trigeminal
Nerve of Cranial Nerves.
Branches
Supratrochlear Nerve
Supraorbital Nerve
Zygomaticotemporal Nerve
Auricotemporal Nerve
10. Innervation of Part of Skull Posterior to
Ear & Vertex of Skull
Innervated by Branches from C2 & C3
of Cervical Nerves.
Branches
Great Aurical Nerve
Lesser Occipital Nerve
Greater Occipital Nerve
3rd Occipital Nerve
13. Arteries of SCALP
Supplied by Branches of External
Carotid & Ophthalmic Artery (Branch
of Internal Carotid Artery)
14. SCALP Blood Supply via Branches
External Carotid Artery
Branches
Superficial Temporal
Posterior Auricle
Occipital Artery
These Branches Supply Posterior &
Lateral Part of SCALP
15. SCALP Blood Supply via Branches of
Ophthalmic Artery
Branches
Supratrochlear
Supraorbital
These Branches supply Anterior and
Superior part of SCALP
16.
17. Veins of SCALP
Same route as Arteries of SCALP.
Supratrochlear & Supraorbital join
and forms Facial Vein
Superficial Temporal forms
Retromandibular vein
Posterior Auricle form External Juglar
Vein
Occipital form Internal Juglar Vein
18. Lymph Drainage of SCALP
It also follows same pattern of Arteries
of SCALP.
Lymph Nodes for Drainage of SCALP
OccipitalNode
Cervical Node
Mastoid Node
Parotid Node
Pre-auricle Node
Sub-Mandibular Node
19.
20. SCALP Lymph Nodes with Area of
Drainage
Occipital & Cervical Node
Both Drain form Occipital Region of SCALP
Mastoid Node
Drains from Posterior to Vertex of Skull
Parotid & Pre-Auricle Node
Drain form Anterior to Vertex of Skull
Sub-Mandibular Node
Drain from Fore Head.
