  1. 1. SCALP Dr. Ankur Saxena Asst. Professor Dept. of Anatomy, SGRR Institute of Medical & Health Sciences, Dehradun, Uttarakhand, India
  2. 2. Scalp
  3. 3. • Covering of Neurocranium. • Extension:- – Supraorbital margins Anteriorly. – Highest Nuchal Line Posteriorly. – Down to the ears at the sides. S = Skin. C = Connective Tissue. A = Aponeurosis With Muscles. L = Loose Areolar Tissue. P = Pericranium.
  4. 4. (Connective tissue)
  5. 5. • Skin – – Thickest – Hairiest & High concentration of Sebaceous glands. – Insertion of Muscle fibers. – Adhered by Connective tissue underneath to the Muscles & Aponeurosis. – Nerves & Vessels run in this layer.
  6. 6. • Occipitofrontalis = Occipitalis & Frontalis • Intervening Aponeurosis = Epicranial aponeurosis = Galea Aponeurotica (Ex. Occ. Pro + Nuchal lines) • Occipitalis Frontalis • Highest nuchal line Front of aponeurosis • Into the Aponeurosis Orb. Oculi+ Eyebrow Post. Auricular N Temporal N.
  7. 7. • Beneath the Muscle & Aponeurosis, Loose areolar tissue. • Avulsion. • Subaponeurotic space extends down beneath Orbicularis oculi into the eyelids.
  8. 8. • Bleeding anywhere beneath the aponeurosis. • Pericranium – Periosteum of the Vault. Loosely attached to the bone. Subperiosteal Hematoma.
  9. 9. • Vascular Supply- Arteries External Carotid Internal Carotid Occipital Supratrochlear Posterior Auricular Supraorbital Superficial Temporal Arterial wall attached to the dense connective tissue
  10. 10. Veins Supraorbital + Supratrochlear Angular Vein Superficial Temporal Vein Retromandibular Vein
  11. 11. Occipital Veins Plexus around Suboccipital Muscle Vertebral Vein Posterior Auricular Vein External Jugular Vein(Behind the ear)
  12. 12. Lymphatic Drainage Anterior Posterior Occipital Nodes Posterior Auricular Nodes Pre-Auricular (Parotid) Nodes Deep Cervical Chain
  13. 13. Nerve Supply • Posteriorly – Greater occipital Nerve (p C2) : Vertex – Third Occipital Nerve (p C3) : Posterior Scalp Behind the ear : Lesser Occipital (a C2). Great Auricular nerve Temple : Auriculotemporal Nerve. Zygomaticotemporal Nerve. Forehead : Supratrochlear nerve. Supraorbital nerve.
  14. 14. APPLIED ANATOMY
