Epidermis - The first Layer
The very first layer of the skin is commonly known amongst the
Dermatological or Biological circles as the epidermis.
This layer of skin is the first of many barriers that protect the skin
from outside influences such as light, heat and infection.
The Epidermis is made up of a principle cell called a keratinocyte. Beyond this and you will find no fewer than
five different layers that make up the Epidermis.
- Stratum
germinativum – This provides the cells which constantly regenerate the
different layers of the epidermis. Magnify this layer enough and you will find
that the germinal cells are divided by a thin layer of material called a
basement membrane.
- Stratum spinosum
– This layer is more commonly known as the prickle-cell layer.
- Stratum
granulosm – This layer helps to form a waterproof barrier which helps the body
remain hydrated.
- Stratum lucidum
- This can normally be seen on the areas of the body where the skin is at its
thickest such as the soles of the feet or the palms of the hand.
- Stratum corneum
– This is where cells are constantly dying a process known as desquamation.
