What are the functions of the pectoral girdle?
Your pectoral girdles are responsible for providing structural support to your shoulder region on the left and right side of your body. They also allow for a large range of motion, connecting muscles necessary for shoulder and arm movement.
Which of the following is not a function of the skeletal system?
Option D:production of body heat: The skeleton serves six major functions: support, movement, protection, production of blood cells, storage of minerals and endocrine regulations. Hence, production of body heat is not a function of the skeletal system. Thus, the answer is option D:Production of body heat.
What are the 5 functions of the skeletal system quizlet?
The five important functions of the skeletal system are support, protection, movement, mineral storage, and blood cell formation. Without our skeleton, our bodies would have no definite shape. The skeleton protects the internal organs. For example, the skull protects the brain.
