Which system is NOT part of the integumentary system?

• A. Skin
• B. Hair
• C. Nervous
• D. Nails

Answer: (C)

The integumentary system is primarily composed of structures that protect the body and help regulate various physiological processes. This includes the skin, hair, and nails, which all play significant roles in protecting internal organs, regulating temperature, and providing sensory information. The nervous system, while it does interact with the integumentary system—particularly in terms of sensation—is not considered part of it. The nervous system is responsible for transmitting signals throughout the body, enabling communication between the brain and various body parts, but it is classified as a separate system that primarily handles sensory and motor functions. Therefore, identifying the nervous system as not part of the integumentary system reflects an understanding of how these biological systems are categorized based on their specific functions and structures.
