True or False: The nervous system releases heat built up by the muscular system.

The statement is false because the nervous system does not directly release heat built up by the muscular system. Instead, the muscular system generates heat as a byproduct of muscle contraction during physical activity. This heat is a result of metabolic processes that occur within the muscles.

The body has mechanisms to regulate temperature, such as sweating and adjusting blood flow to the skin, which are controlled by the nervous system. However, it is important to note that the nervous system itself does not release heat; instead, it coordinates responses that manage the body's temperature in relation to heat generated by the muscles.
