What is the outer layer of skin called?

The outer layer of skin is referred to as the epidermis. This layer serves as a crucial protective barrier for the body, shielding it from environmental factors like pathogens, chemicals, and physical damage. The epidermis is composed primarily of a specialized type of epithelial tissue and is responsible for the skin's overall appearance and function.

In addition to protecting, the epidermis also plays a vital role in the regulation of moisture loss and can provide insight into the overall health of the organism. This layer contains no blood vessels, relying instead on the underlying dermis for nutrients and support, which is why it is successful in forming a robust protective covering.

Understanding the structure of the skin is important in veterinary science, as various skin conditions and diseases affect different layers and can significantly impact an animal's health and wellbeing.
