Magnified section of scalp
Magnified section of scalp, historical artwork. The external surface is the cuticle, with the layer of skin below this known as the rete mucosum, or epidermis. Deeper in is the living layer, known as the dermis, consisting of the papillary layer and corium. Deeper still is the subcutaneous fatty layer (yellow, bottom). The hair shafts are flanked by sebaceous follicles (yellow), and emerge from sudoriferous follicles. From The Nerves of the Human Body (1839)

EDITORS COMMENTS
This print showcases a magnified section of the scalp, revealing intricate details of its anatomy and physiology. Dating back to 1839, this historical artwork from "The Nerves of the Human Body" offers a fascinating glimpse into our biological makeup. At first glance, we observe the external surface known as the cuticle, which serves as a protective layer for the underlying skin. Just below it lies the rete mucosum or epidermis, playing a crucial role in maintaining skin health. Delving deeper into this living layer is the dermis, consisting of two distinct parts - the papillary layer and corium. These layers contribute to various physiological functions that keep our scalp healthy. Further down lies the subcutaneous fatty layer depicted in yellow hues at the bottom. This adipose-rich region provides insulation and cushioning for our head while also storing energy reserves. Amongst these anatomical marvels are hair shafts flanked by sebaceous follicles responsible for oil production and sudoriferous follicles through which sweat emerges. Together they play vital roles in regulating body temperature and protecting against environmental factors. This mesmerizing illustration not only highlights key components of our scalp but also reminds us of how intricately woven our bodies are. It serves as an invaluable resource for those interested in biology, anatomy, or simply appreciating art that celebrates human physiology's wonders.
