2. There are several different cells in the
epidermis:
• Keratinocytes
• Melanocytes
• Langerhans cells

3. • Keratinocytes (basal
cells) make up the
majority of cells in the
epidermis. They
produce keratin.
Keratin is present in
most cells of the
epidermis. As a cell
moves towards the
skin’s surface, the
amount of keratin
increases.
• KERATIN – an insoluble
protein which makes the
cell more resilient.

4. • They produce the
pigment melanin which
gives colour to the skin
and hair.
• Melanin granules are
formed in the
melanocytes which
pass along finger-like
projections called
dendrites that inject
melanin into the
surrounding skin cells.

5. • Specialised white
blood cells which
circulate in the skin.
• They are cells of the
immune system which
remove cell debris
and pathogens.
