Layers of the Scalp
- The layers of the scalp from superficial to deep are: skin, connective tissue, aponeurotic, loose areolar, and pericranium

Boundaries of the Scalp
- The scalp is bounded posteriorly by the external occipital protuberance and the superior nuchal lines
Aponeurotic Layer
- The occipitalis muscle is associated with the aponeurotic layer of the scalp
Deep to the Connective Tissue Layer
- The loose areolar tissue layer is found deep to the connective tissue layer of the scalp
Test your knowledge of scalp anatomy by answering questions about the layers of the scalp, as well as the arteries and nerve supply to the scalp. Learn from Dr. Morton, a noted anatomist, as he explains the boundaries and features of the scalp.
