What is The layer of soft keratin within the hair shaft?
Medulla
What are the three main layers of the hair shaft?
Medulla layer
What are 3 layers of hair?
The 3 layers of hair are the Cuticle (the outer most layer), the Cortex (the middle layer), and the Medulla (the inner most layer).
What is a Cortex in the hair and what does it do?
Structure of the hair shaftYour smooth, glossy hairs have a more complicated structure than you might think. Each one can be compared to a tree: all its moisture lies in its centre, behind a tough outer layer of protective bark. If the 'bark' of the hair is well looked after the whole hair remains in good condition. If the 'bark' is stripped off to expose the centre the hair may break.The centre part of the hair, called the cortex, makes up most of the hair shaft. It is the cortex that gives hair its special qualities such as elasticity and curl. The cortex is packed with strands of keratin, lying along the length of the hair. These keratin fibres are made of the low-sulphur keratins, and are compressed into http://www.pg.com/science/haircare/hair_twh_14.htm
What part of the hair extends from the hair papilla to the body surface?
That part is called as hair root. There is very tiny muscle, attached to it.
What are cuticle scales?
Cuticle scales are formed from dead cells on the hair cuticle, which is the outer layer of the hair shaft. The scales give the hair shaft strength.
What layer of hair that is responsible for porosity of the hair?
The cuticle, which is the outermost layer of the hair shaft.
What are the three main layers of the hair shaft?
Medulla layer

Medulla

What is the outermost toughest portion of the hair called?
the cell wall is the outermost part of the human skin and also the outermost layer of all plants its called the epidermous
Are fingernails dead?
Yes. As is hair and the outer layer of the skin.
What are the layer of the hair?
cuticle, cortex, and medulla (outer to inner)
The externally observable part of a hair?
Actually, the correct answer is the Hair Shaft.The hair root is found in the dermis layer of your skin,and the epidermis is the observable layer of skin, in which the hair shaft is seen.
What is visible part of the hair called?
Hair Shaft

How can your hair change from straight to curly?
The helical structure of the hair remains the same, but the orientation of the strands changes. At the points where the curls begin, the outer layer develops tiny kinks, while the inner layer becomes straighter. This means that the direction of each straight hair strand shifts around the hair shaft.
