Case Study Assignment: Structure and Function of the Skin
Yael is an 18-year-old college student who is bothered by excessive perspiration. She knew she sweat a lot under her arms and kept antiperspirant in her schoolbag to use throughout the day. Yael’s problem was not limited to under her arms, however. Her hands and feet also perspired heavily, and it embarrassed her. She did not like holding her boyfriend’s hand if her hands were particularly sweaty, and she had problems grasping her pen while in class because her palm became slippery. Yael suffered from a condition called primary focal hyperhidrosis, a condition involving hyperactive sweat glands in certain areas of the body.

- What autonomic nervous system controls the function of thermoregulation of the skin? How do goosebumpsgoose bumps contribute to heat conservation?
- Describe the location of the blood plexuses in the skin. How is blood circulation to the skin involved in thermoregulation?
Skin has three layers: The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands. The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.
