Integumentary System

The specializations upon our skin surface have many different roles and functions. In development, it is initially the distribution or "pattern" that is of interest.

Hair

• Before birth we have embryonic hair that has an imporant role in binding the skins waxy protective coating against our watery environment.
• After birth we have early postnatal hair that is gradually replaced by the mature form.
• At puberty we have a second round of hair formation under endocrine regulation by sex hormones.
