What is the clinical anatomy associated with the scalp?

What is the clinical anatomy associated with the scalp?

The scalp consists of five layers. The first three layers are tightly bound together and move as a collective structure. The mnemonic ‘SCALP’ can be a useful way to remember the layers of the scalp: Skin, Dense Connective Tissue, Epicranial Aponeurosis, Loose Areolar Connective Tissue and Periosteum.

What kind of connective tissue is in the scalp?

Also referred to as the superficial fascia, the connective tissue of the scalp is a fibrofatty layer. This layer forms the bridge between the skin and the epicranial aponeurosis by connecting the two together. The loose areolar tissue forms a loose connection between the epicranial aponeurosis and the pericranium.

What nerve Innervates the scalp?

Anatomy. The greater occipital nerve (GON) is the medial branch of the dorsal ramus of the second spinal nerve (C2); it provides cutaneous innervation to the major portion of the posterior scalp.

What are the layers of the skull?

There are 3 layers of tissue called meninges that help protect the brain. The outer covering of tissue (called the dura mater), closely lines the inside of the skull. The second layer is the arachnoid mater, and the third layer, the pia mater, hugs the surface of the brain.

Is the scalp thick or thin skin?

The face and the scalp are connected with one thin sheet of skin. The skin structure is pretty much the same, but scalp skin is one the thickest skin in the body. It measures up to 8mm!. It also carries more blood than the rest of your skin.

What is between the skull and skin?

Connective tissue. The tissue between the skin and the aponeurotic layers is composed of dense collagenous connective tissue and contains the arteries, veins and nerves supplying the scalp.

Where is the thinnest skin on your body?

Skin is thickest on the palms and soles of the feet (1.5 mm thick), while the thinnest skin is found on the eyelids and in the postauricular region (0.05 mm thick).

What are the five layers of the scalp?

The scalp consists of five layers of tissue. The five layers, from superficial to deep, are skin, subcutaneous connective tissue, a muscular aponeurotic layer, a loose connective tissue layer, and the pericranium.

What are the parts of the scalp?

The scalp consists of 5 layers (seen in the image below): the skin, connective tissue, epicranial aponeurosis, loose areolar tissue, and pericranium. The first 3 layers are bound together as a single unit.

What part of the head is the scalp?

The human scalp is the top and back part of the head, including a small area on the sides, which is bordered by the face in the front and neck at the back. Commonly, most people refer to the scalp as the head, although it is only one part of the head and the area where the most amount of hair grows.

What is the function of the scalp?

The scalp is the same as skin on other parts of our body, and has lipid glands and sweat glands. Like other parts of skin, the scalp’s stratum corneum (skin’s outer layer) is only 0.02mm thick, but it plays an important role in protecting our body against external irritation.
