There are four cell types found in the epidermis |
Keratinocytes. Produces tough protein called keratin . Melanocytes. Pigment cells located deep in the epidermis they also produce melanin which is responsible for skin color . Merkel cells. Are sensory cells. And langerhans cells. Wandering macrophages. |

Corneum. Lucidum. Granulosum. Spinosum. Basale. |
|
|

Location of melanocytes. Cells in this area are undergoing active reproduction. |
|
|

Keratinocytes are bound together by desmosomes. |
|
|

Keratinocytes produce lots of keratin |
|
|

Why do we get wrinkles |
The interwoven collagen fibers provide tensile strength the elastic fibers allow the skin to stretch and recoil but skin wrinkles are due to age change of hormone levels and UV light |
|
|
Stretch marks and why we get them |
Extensive stretching during pregnancy excessive waking can cause reticular fibers to break. The skin does not require. The skin wrinkles and creases result in stretch marks. |
