The five major structures of the brain are myelencephalon‚ Metencephalon‚ mesencephalon‚ diencephalon and telencephalon. The myelencephalon carries signals from the brain to the entire parts of the human body and it is also uniquely shaped looking like a little net. The Metencephalon is made up of ascending and descending tracts just like the myelencephalon. It has two major divisions which are pons and the cerebellum. The mesencephalon has two divisions also and they are the tectum and the tegmentum

The Integumentary system is considered the largest system in the human body that protects it from various kinds of damage‚ however this does not prevent skin disorders to appear. Keloids is a skin disorder that results from the overgrowth of scar tissue that occurs at the site of a skin injury.
