Transcript of "Scalp Anatomy"

  1. 1. Anatomy of SCALP S.S Hotchandani
  2. 2. Structure  Part of Head.  Extend from Superciliary arches anterior, to superior nauchal lines posterior.  Made of 5 Layers
  3. 3. Layers of SCALP  Skin  Connective Tissue (Deep)  Apo neurosis  Connective Tissue (Loose)  Periosteum
  4. 4. 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
  5. 5. FrontalProcess Occipital Process
  6. 6. 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
  7. 7. Innervations of Part of SCALP anterior toEar & Vertex of Skull  Innervated by Branches of Trigeminal Nerve of Cranial Nerves.  Branches  Supratrochlear Nerve  Supraorbital Nerve  Zygomaticotemporal Nerve  Auricotemporal Nerve
  8. 8. Innervation of Part of Skull Posterior toEar & 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
  9. 9. Blood Supply of SCALP  Arterial  Venous
  10. 10. Arteries of SCALP  Supplied by Branches of External Carotid & Ophthalmic Artery (Branch of Internal Carotid Artery)
  11. 11. SCALP Blood Supply via BranchesExternal Carotid Artery  Branches  Superficial Temporal  Posterior Auricle  Occipital Artery  These Branches Supply Posterior & Lateral Part of SCALP
  12. 12. SCALP Blood Supply via Branches ofOphthalmic Artery  Branches  Supratrochlear  Supraorbital  These Branches supply Anterior and Superior part of SCALP
  13. 13. 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
  14. 14. 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
  15. 15. SCALP Lymph Nodes with Area ofDrainage  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.
