Face, Scalp, Neck
• Skin
• Superficial fascia
• Muscles of facial expression
• Blood supply, nerve supply, and lymphatic drainage
Skin and superficial fascia
-The skin of the face possesses numerous sweat glands, sebaceous glands, and hair in some
-Superficial Fascia lies under the skin, in which are embedded the muscles of facial
- No deep fascia is present in the face
Muscles of facial expression
-They are in the superficial fascia, with origins from either bone or fascia, and insertions into
the skin.
-They are innervated by facial nerve.

Arterial Supply
Mainly from branches of external carotid artery, though there is some limited supply from a
branch of the internal carotid
1)Facial artery
2)Transverse facial artery
3)Maxillay artery
4)Zygomaticofacial artery
5)Dorsal nasal artery
Venous drainage
- Most of the venous return is back to the internal jugular vein, though some important
connections from the face result in venous return through a clinically relevant intracranial
pathway involving the cavernous sinus.

Lymphatic drainage
Lymphatic drainage from the face primarily
moves towards three groups of lymph nodes:
1)Submental nodes
2)Submandibular nodes
3)Pre-auricular & Parotid nodes
Nerve supply

It’s a multi-layered soft tissue structure that covers cranium, it extends from supraciliary arch
anteriorly to the superior nuchal line, and external occipital protuberance posteriorly,

1- Supraorbital a.
2- Supratrochlear a.
3- Zygomaticotemporal a.
4- Superficial temporal a.
5- Posterior auricular a.
6- Occipital a.
* Veinous return correspond to the Arteries
Nerve supply
1- Supraorbital n.
2- Supratrochlear n.
3- Zygomaticotemporal n.
4-Auricuotemporal n.
5- Lessor Occipital n.
6- Greater Occipital n.
It’s a region of the body that lies between the lower margin of the mandible and the superior
nuchal line of the occipital bone above , and the suprasternal notch and the upper border of
the clavicle below.
Skin and Cutaneous nerves of the neck
• The skin on the back of the neck, and back of the scalp as high as the vertex is supplied
by posterior rami of cervical nerves ( C2-5)
• The skin of the front and the sides of the neck is supplied by anterior rami of cervical
nerves ( C2-4) through the branches of cervical plexus.
• The skin of the face, forehead and scalp anterior to vertex is supplied by branches of
Trigeminal nerve***.
Cutaneous nerves of the neck
Greater occipital nerve ( C2)
Lesser occipital nerve ( C2)
Great auricular nerve ( C2 & C3)
Transverse cutaneous nerve of the neck ( C2 & C3)
Supraclavicular nerves (C3 & C4) : ( medial, intermediate, lateral)
Posterior rami of C3,C4, and C5

Superficial fascia of the neck
It’s a thin layer which underlies the skin of the neck, invests Platysma, and also embedded in it
are cutaneous nerves, superficial veins and superficial lymph nodes of the neck
