What Are The Five Layers Of The Scalp? | Parts of the Scalp
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.

Muscles of the scalp
There are two muscles one is the galea and the second is the occipitalis. The first muscles are can be attached to the galea(frontalis), and the second muscles are can be attached to the occipitalis(behind).
