What is included in the integumentary system?

The integumentary system is primarily responsible for protecting the body and has several important components that contribute to this function. It includes the skin, which acts as a barrier against environmental hazards, regulates temperature, and enables the sensation of touch, pressure, pain, and temperature. Additionally, the integumentary system encompasses hair and nails, which protect the skin and enhance sensory perception. Sweat glands play a crucial role in thermoregulation and waste excretion, while sebaceous glands produce oil to keep the skin and hair moisturized.

Understanding the functions and components of the integumentary system is fundamental to comprehending overall human physiology and health, especially in the context of conditions resulting from brain injuries, where skin integrity and sensory functions may be impacted.
