First of all, muscles are not the source of body heat. It is the metabolism that they undergo that produce heat. Each time a muscle move (involuntary, voluntary, or cardiac), a certain amount of calorie is required to be burned to effect a muscle contraction. For carbohydrates and proteins as fuel, we extract 4 calories per gram., For fats, it's about 9 calories per gram, though the body never directly always use the latter because of toxic by-products at the end of the reaction. The successive contraction and relaxation of muscles, as in running or exercising might give an idea to a layman that the muscles are the major source of body heat, but in the medical and scientific discipline, it is not. Teachers, especially Science teachers, must be trained in English as well, to be able to deliver to their pupils the exact skills, knowledge, and training in a systematic way, including asking questions that are not out of order.
The most major heat source of the body is the blood cells in our body, however it can be our muscles as well.
Skeletal muscles help regulate body temperature by generating heat through muscle contractions. When the body is cold, muscles shiver to produce heat, raising body temperature. Conversely, when the body is hot, muscles relax to release heat, helping to cool the body down.
Muscles generate heat through contraction which helps to regulate body temperature. When the body is cold, muscles shiver to produce heat, while during exercise, muscles generate heat to maintain body temperature. Additionally, increased blood flow to muscles during activity helps to dissipate excess heat and maintain a stable body temperature.
The major organ in the muscular system is the skeletal muscles. These muscles work together to help the body move, maintain posture, and generate heat. They contract and relax in response to signals from the nervous system, allowing for voluntary movement and supporting the body's structure.
Body heat is produced within your cells. For one, when you exercise the chemical energy used in the muscles contracting is not efficiently turned into mechanical energy and the excess is lost as heat. The various metabolic reactions occurring withing your body also produce heat such as the breakdown of chemicals within your cells. There really is no one place where body heat is produced. Hope this helps!

They constrict, cramp, & spasm in an attempt to prevent losing body heat.
Muscles generate heat as they contract, which helps to maintain body temperature in cold conditions. This heat production, known as thermogenesis, is an important mechanism that allows the body to regulate its temperature and stay warm. Additionally, the increased blood flow to muscles during exercise can also contribute to keeping the body warm.
Muscles produce heat in the body through a process called cellular respiration. During this process, glucose is broken down in the presence of oxygen to produce energy in the form of ATP. Some of this energy is released as heat, which helps to maintain the body's temperature.
Muscle activity produces heat so that exercise creates a heat surplus that can actually be fatal. In response to exercise the body has to redirect blood flow to the skin to facilitate heat transfer out of the body.
