Scalp's Anchor Layer

This layer of the scalp, composed of dense connective tissue, firmly attaches the skin to the third layer. It also houses blood vessels and nerves that supply the scalp.

Occipitofrontalis Muscle

This muscle is responsible for moving the scalp, wrinkling the forehead, and raising the eyebrows. It has two parts: the frontal belly and the occipital belly.

Frontal Belly

This is the front part of the occipitofrontalis muscle. It's connected to the occipital belly by a strong tendon.

Epicranial Aponeurosis

This is a strong, flat sheet of connective tissue that covers the top of the skull. It's part of the deepest layer of the scalp.

Profuse Bleeding in Scalp

Cutting the scalp often leads to a lot of bleeding because the dense connective tissue holds the blood vessels open, preventing them from constricting.

Study Notes

Scalp Anatomy

The connective tissue layer of the scalp anchors the skin to the deeper layers and contains arteries, veins, and nerves that supply the scalp.
The galea aponeurotica is the tendon that connects the frontal belly and the occipital belly of the occipitofrontalis muscle, allowing movement across the forehead and scalp.
The occipitofrontalis muscle is responsible for moving the scalp, wrinkling the forehead, and raising the eyebrows, facilitating expressions.
The deepest layer of the scalp consists of the occipitofrontalis muscle along with the epicranial aponeurosis, providing a supportive structure for movement.
Cutting the scalp leads to profuse bleeding due to a rich vascular supply and the presence of many small blood vessels that do not constrict easily.
