Your scalp is made of skin layers. Your cranial vault bones are covered by subcutaneous tissue, hair scalp is like soft tissue. 


They help you to protect your cranial vault from infectious agents. Your scalp is divided into 5 layers. SCALP = {(S – SKIN)+ (C – CONNECTIVE TISSUE)+ (A – APONEUROSIS) + (L – LOOSE CONNECTIVE TISSUE)+ (P -PERICRANIUM OR PERIOSTEUM)}.


Here are the parts of the scalp or layers of the scalp:

  • 1. Skin: The first layer of your scalp is skin. This is the skin from where your hair grows. Your skin contains your all hair follicles and your sebaceous glands.
  • 2. Connective Tissue: The second layer of your scalp is Dense connective tissue. It also knows as Dense connective tissue or superficial fascia. Your Dense connective tissue is made of subcutaneous layers like fat, blood vessels, nerves, and the lymphatic system.
  • 3. Aponeurosis: The third layer of your scalp is Aponeurosis. It is also known as epicranial aponeurosis or galea aponeurotica. Aponeurosis is a tough layer of your scalp that keeps the frontalis muscles and occipitalis connected.

Action Of Occipitofrontalis Muscle :


A. Frontal belly

This helps you to move the scalp forward

This helps you to raise the eyebrows

This helps you to cause horizontal wrinkles on the forehead


B. Occipital belly

This helps you to move the scalp backward


  • 4. Lose Areolar Connective Tissue

The fourth layer of your scalp is Loose Areolar Connective Tissue. It helps to make an easy plane of separation or flexible plane separating between the upper three layers and the pericranium.



This layer is like a danger zone(a dangerous area of the scalp). Because when it is infected, it can spread in the whole tissue and pass on pericranium. Many cells are here in the Loose Areolar Connective Tissue layer like plasma cells, mast cells, and adipocytes.


  • 5. Pericranium

The fifth layer of your scalp is Pericranium. The periosteum is an outer layer of pericranium.  pericranium also provides nutrition to the bone. Pericranium is a dense or irregular connective tissue.



Nerve supply of scalp | nerves of the scalp


A. Trigeminal Nerve

  • Supratrochlear nerve.
  • Supraorbital nerve.
  • Zygomaticotemporal nerve.
  • Auriculotemporal nerve.
  • Cervical Nerves


B. Lesser occipital nerve

  • The greater occipital nerve.
  • The great auricular nerve.
  • The third occipital nerve.


Arterial Supply


Three branches are involved:

  • Superficial temporal
  • Posterior auricular
  • Occipital

Scalp veins | veins of the head


The scalp veins primarily drain the deoxygenated blood from the epicranial aponeurosis. The superficial veins of the scalp start anteriorly and move posteriorly.


Scalp anatomy


The scalp is like soft tissue layers.  The soft tissue layers cover the skull. The cranium is an anatomic region bordered anteriorly by the face, and posteriorly by the neck.


Parietal Scalp


There is a Parietal region between the temple and occipital scalp. There lies between the vertical lines in front, and also behind the ear.


scalp vertex


a vertex or posterior hairline is an area where the scalp goes horizontal to a vertical plane posteriorly.
