Huxley's Layer

Huxley's Layer (pronounced: HUHK-sleez LAY-er) is a term used in anatomy and histology to describe a specific layer within the hair follicle. It is named after the British biologist, Thomas Henry Huxley, who first identified it.

Etymology

The term "Huxley's Layer" is derived from the name of its discoverer, Thomas Henry Huxley, an eminent English biologist known as "Darwin's Bulldog" for his advocacy of Charles Darwin's theory of evolution. The term "layer" is used in histology to describe a level or stratum of cells or tissue.

Description

Huxley's Layer is one of the three concentric layers of cells that make up the hair shaft. It is located between the Henle's layer and the cuticle, the outermost layer of the hair shaft. The cells in Huxley's Layer are flattened and filled with keratin, a type of protein that gives hair its strength and flexibility.
