Integumentary system anatomy from "summary" of The Anatomy of the Domestic Animals by Robert Getty
The integumentary system provides protection to the body from various external elements such as bacteria and viruses. It also helps control the body's temperature and synthesize vitamin D. This system is composed of the skin, hair, nails, and glands.- The integumentary system is a complex system in the body responsible for protection of vital organs and tissues. It consists of layers of specialized cells, which are made up of collagen, elastin, and flax proteins.
- With regards to humans, our integumentary system protects us from pathogens, irritants, dehydration, UV damage, and maintains homeostasis of the body temperature.
- Hair is an important aspect of integumentary anatomy as it helps trap air near the surface of the skin which provides insulation against the heat or cool air. It also plays an important role in providing sensory feedback from its tactile characteristics.
- This system consists of skin, hair, nails, sweat glands, sebaceous glands, and other special structures like feathers, scales, and talons. Depending on the species of animal, this system can vary in complexity and structure.
- Talons are another important structure associated with integumentary anatomy. These also provide protection from physical attacks, helping birds, reptiles, and even mammals grasp food securely.
- All in all, integumentary anatomy is a complex network of structures that works together to maintain and protect the health of animals and people alike.
- In addition, it helps in excretion through sweating and secretion of hormones from sweat glands that secrete pheromones and other substances essential to our overall functioning.
- Sebaceous glands secrete lipid-based oils that help keep the skin soft and lubricated. Depending on the location on the body, these glands help protect us from microbes, allergens, friction, and water loss.
- Special structures such as feathers and scales play different roles depending on the type of bird or reptile being consulted. For instance, feathers act as insulation material and as structural support while scales create an effective layer of armor against predators.
- Nails help to provide additional protection to the fingertips by enabling us to grip objects easily.
