During his original examination, Henle believed the layer lacked nuclei because he viewed it at a level where it had already cornified. [3] Huxley's layer is in the middle, made up of approximately two rows of flattened cells with granular protoplasm. The cuticle of the root sheath is in the center, continuous with the outermost layer of the ...
Huxley's layer is the second layer of the inner root sheath of the hair and consists of one or two layers of horny, flattened, nucleated cells. It lies between Henle's layer and the cuticle . [ 1 ]
a delicate cuticle next the hair, composed of a single layer of imbricated scales with atrophied nuclei; Huxley's layer; Henle's layer; The term "trichilemmal" refers to the outer root sheath. [2] The IRS functions to mould, adhere, as well as participate in the keratinization of growing hair. [3]
The base of a hair's root (the "bulb") contains the cells that produce the hair shaft. [12] Other structures of the hair follicle include the oil producing sebaceous gland which lubricates the hair and the arrector pili muscles, which are responsible for causing hairs to stand up.

Anatomy of hair Diagram of the hair shaft, indicating medulla (innermost), cortex, and cuticle (exterior.) The medulla is the innermost layer of the hair shaft. This nearly invisible layer is the most soft and fragile, and serves as the pith or marrow of the hair. Some mammals don't have a medulla in their hair. The presence or absence of this ...
Diagram of the hair shaft, indicating medulla (innermost), cortex, and cuticle (exterior.) Anatomy of hair. The cortex of the hair shaft is located between the hair cuticle and medulla and is the thickest hair layer. It contains most of the hair's pigment, giving the hair its color. The major pigment in the cortex is melanin, which is also ...
