What is the name of this type of cell and what is the name of the special substance

It seems like oligodendrocytes, and the substance is myelin

The stages of hair growth:
Anagen = growth stage; hair matrix cells divide & the hair grows outward
Catagen = regression stage, when the hair stops growing and it atrophies
Telogen = resting stage
After the telogen stage, a new hair begins to grow and pushes the old hair out of its follicle, and the cycle repeats

I forgot to hide my answer! Oops >_>
Okay, whatever. Next question: which class of major histocompabitility complex (MHC) proteins (also known as human leukocyte proteins, or HLA) appears on the surface of antigen-presenting cells?

Nope, try again
EDIT: antibodies are not a class of MHC proteins...
