2. Hair follicle - Wikipedia

   en.wikipedia.org/wiki/Hair_follicle

   The papilla is a large structure at the base of the hair follicle. [4] The papilla is made up mainly of connective tissue and a capillary loop. Cell division in the papilla is either rare or non-existent. [contradictory] Around the papilla is the hair matrix. A root sheath composed of an external and internal root sheath.

4. Stratum corneum - Wikipedia

   en.wikipedia.org/wiki/Stratum_corneum

   The cytoplasm of its cells shows filamentous keratin. These corneocytes are embedded in a lipid matrix composed of ceramides, cholesterol, and fatty acids. [3] Desquamation is the process of cell shedding from the surface of the stratum corneum, balancing proliferating keratinocytes that form in the stratum basale. These cells migrate through ...

5. Hair keratin - Wikipedia

   en.wikipedia.org/wiki/Hair_keratin

   Encircling these cells is the matrix cell region, the hair follicle's proliferative compartment, responsible for the formation of different follicle compartments (except the ORS) and the production of crucial structural elements of hair - hair keratins and associated proteins known as KAPs. [1]

6. Matrix (biology) - Wikipedia

   en.wikipedia.org/wiki/Matrix_(biology)

   Matrix (biology) In biology, matrix (pl.: matrices) is the material (or tissue) in between a eukaryotic organism's cells. The structure of connective tissues is an extracellular matrix. Fingernails and toenails grow from matrices. It is found in various connective tissues.

7. Cortex (hair) - Wikipedia

   en.wikipedia.org/wiki/Cortex_(hair)

   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 found in skin. The distribution of this pigment varies from animal to animal and person to person.

8. Hair cell - Wikipedia

   en.wikipedia.org/wiki/Hair_cell

   In mammalian outer hair cells, the varying receptor potential is converted to active vibrations of the cell body. This mechanical response to electrical signals is termed somatic electromotility; [13] it drives variations in the cell's length, synchronized to the incoming sound signal, and provides mechanical amplification by feedback to the traveling wave.

9. Trichocyte (human) - Wikipedia

   en.wikipedia.org/wiki/Trichocyte_(human)

   Trichocyte (human) In mammals, trichocytes are the specialized epithelial cells from which the highly mechanically resilient tissues hair and nails are formed. They can be identified by the fact that they express "hard", "trichocyte" or "hair" keratin proteins. [1] These are modified keratins containing large amounts of the amino acid cysteine ...
