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.
