The sympathetic nervous system is continuously monitoring body temperature and initiating appropriate motor responses. The integumentary system helps regulate body temperature through its tight association with the sympathetic nervous system, the division of the nervous system involved in our fight-or-flight responses. The integumentary system functions are varied but overall it provides a barrier that protects our body from infection. Bird feathers are made out a central shaft called a rachi, a base called a calamus (also called the quill) and the barbules that form the actual soft part.
