Anatomy of Scalp Layers Quiz

Scalp Anatomy

• The skin is located anteriorly to the scalp.
• The 'C' in the word 'SCALP' corresponds to the connective tissue layer of the scalp.
• The function of the connective tissue layer of the scalp is to provide a loose areolar tissue layer that allows for movement of the scalp.
• The layers of the scalp, arranged from outwards inwards, start with the skin.
• The galea aponeurotica gives attachment to the occipito-frontalis muscle in the scalp.
• The frontalis muscle elevates the eyebrows, as in surprise.
• The nerve supply to the Occipitalis muscle is provided by the posterior branch of the facial nerve (cranial nerve VII).
• The occipital bellies of the Occipito-frontalis muscle arise from the occipital bone.
• The scalp behind the ear is known as a "Dangerous area" due to the loose areolar connective tissue (CT) located there.
• The posterior auricular artery is responsible for supplying blood to the scalp behind the ear.
