Which is not a function of the integumentary system?

• A. To Protect the Body from Infection
• B. To Regulate Body Temperature
• C. Motor Control
• D. Excrete Waste

Answer: (C)

The integumentary system, which includes the skin, hair, nails, and associated glands, serves several essential functions in maintaining overall health and homeostasis. One of its primary roles is to protect the body from infection, acting as a barrier against pathogens. Additionally, it plays a crucial part in regulating body temperature through processes like sweating and blood flow to the skin. Another significant function of the integumentary system is the excretion of waste through sweat, which can contain substances like salts and urea. This is part of the body's overall waste management system. Motor control, however, is not a function associated with the integumentary system. Instead, motor control is primarily governed by the nervous system, which coordinates muscle movement and responses. Therefore, in the context of the question, motor control is correctly identified as not being a function of the integumentary system, highlighting how this system focuses more on protective, regulatory, and excretory roles rather than directly controlling movement.
