As more atoms are bonded together, they start to form a chain, this chain
is fibrous and is called a Micro fibril. This Micro fibril joins together with
6 or 7 other Micro fibrils to become a Fibril. Many Fibrils join together
and become a cortical cell. Many cortical cells join together in a circular
formation creating a hollow tube down the centre known as the Medulla.
All these cortical cells are known as the Cortex which is held together
with protein cement, known as the Matrix.

At the same time as the cortical cells are being formed, other atoms are
creating smaller flat cells (cuticle scales) which are being forced against
the walls of the epithelial sheath, as the cortical cells grow up the
epithelial sheath, they collect the cuticle scales from the sides of the
epithelial sheath, forming a flexible fence around the cortical cells, rather
like a leg inside a stocking. (Fig 13.)

Caucasian, Asian and Black hair (African/Caribbean Decent) all have
seven layers of cuticle scales holding all the cortical cells together.
Whereas, Oriental hair has fourteen layers of cuticle scales holding the
cortical cells together.
