Hair shaft anatomy, artwork
Hair shaft anatomy. Cutaway artwork showing the internal structure and anatomy of a human hair. Hair is made of a fibrous protein called keratin, with an outer cuticle layer protecting the inner cortex and medulla layers. The medulla is at the centre of the shaft, surrounded by cortical bundles that consist of various sizes of fibrils and filaments. The hair shaft arises from a hair follicle below the surface of the skin, with the emergence from the skin shown at bottom

EDITORS COMMENTS
This print by Claus Lunau from Science Photo Library showcases the intricate and fascinating anatomy of a human hair shaft. Against a clean white background, this artwork provides a cutaway view that reveals the internal structure of our hair. The hair shaft, composed primarily of keratin, is depicted with its outermost layer known as the cuticle. This protective layer shields the inner cortex and medulla layers, which are responsible for providing strength and flexibility to our strands. At the core of the hair shaft lies the medulla, surrounded by cortical bundles consisting of various sizes of fibrils and filaments. The emergence of the hair shaft from a follicle beneath our skin is also highlighted in this illustration. It serves as a reminder that healthy hair growth originates deep within us. With its meticulous attention to detail, this artwork not only appeals to those interested in biology but also offers valuable insights into dermatology and anatomical studies. By showcasing both normal and healthy features, it allows viewers to appreciate the complexity hidden within something seemingly simple like our own hair. Claus Lunau's skillful portrayal captures both scientific accuracy and artistic beauty in this stunning representation of one small aspect of human physiology - reminding us once again how remarkable even everyday elements can be when examined closely.
