Q:

How do skeletal muscles contribute to homeostasis?

A:

Quick Answer

Skeletal muscles help maintain homeostasis by shivering to raise the body temperature or helping the human to move. Humans move from one place to the next to obtain the resources they need, such as food and water. Food, water and other resources help the body’s internal mechanism maintain homeostasis.

The human body is designed to operate at a rather narrow temperature range of approximately 98.6 degrees Fahrenheit. If the body’s core temperature rises far above this or falls far below this, the body can stop functioning properly. To provide some insurance against these temperature variations, the skeletal muscles help transport the human to a place with a more moderate temperature. Alternatively, the human could use their skeletal muscles to build a shelter or light a fire. However, in circumstances in which a human has no way to escape the cold temperatures, the skeletal muscles begin shivering. This shivering motion causes friction to occur, which generates heat for the body and helps the human to maintain homeostasis.

Sometimes, the skeletal muscles work in opposition to homeostasis. For example, during exercise — which relies on the functioning of skeletal muscles – pulse rate, blood pressure and breathing rate must change to offset the high oxygen demands of the muscles and the increased temperature to the body, in order to maintain homeostasis.
