Web the hair shaft consists of an inner core known as the medulla. This layer aids in hair elasticity, strength, color, and texture. It is also responsible for making the hair shaft rigid, which helps to protect the hair from damage.
Web The Medulla Is The Innermost Part Of The Hair Shaft, Can Be Continuous, Discontinuous, Segmented Along The Shaft, Or Even Absent, Depending On The Type, Caliber, And Age Of The Fiber, And It Is Part Of The Excretory System Of The Human Body.
This nearly invisible layer is the most soft and fragile, and serves as the pith or marrow of the hair. This is surrounded by the cortex, which makes up the bulk of the hair. Medulla is the central core of hair which may or may not be present.
The Presence Or Absence Of This Layer And The Characteristics Of The Medulla Can Aid Taxonomists In Identifying What Taxa A Hair.
This is the innermost portion of the shaft that consists of air spaces and a thin core of cells. Web medulla of the hair (histological slide) the fourth cell layer of the hair follicle comprises the internal root sheath. This is called the medulla.
The Presence And Appearance Of Medulla Vary From Individual To Individual And Even Among The Hairs Of The Same Individual.
The shaft cuticle is then encased in three layers that form the inner (internal) root sheath. This is to leave a space into which sebum can be secreted around the hair. If the medulla is present, its structure may be continuous or fragmented.
New Cells Are Constantly Forming In The Hair Bulb.
The medulla is not always visible because it can be quite thin. Moving outwards, there is a single layer of cells making up the shaft cuticle. Web examples of terminal hairs include the hair on your head, facial hair, eyelashes, eyebrows, pubic hair, chest hair and belly hair.
The Full Strand Of Hair Develops From This Group Of Hardened Hair Cells.
Web the inner layer: Web the cortex forms the main bulk and pigment (colour) of your hair. The health of your cortex depends largely on the integrity of the cuticle protecting it.
