2. Functions of the Muscular System 1. Stabilize joints with their TENDONS 2. Produce movement (including standing upright) 3. Produce heat to maintain body temperature

4. Skeletal Muscle 0 Attaches to bone, skin, or fascia (connective tissue) 0 Striated muscle 0 Muscle fibers are bands of dark & light tissue. 0 Function in pairs to bring about the co-ordinated movements of the limbs, trunk, jaws, eyeballs, etc. 0 Voluntary control of contraction & relaxation Picture from http://www.gwc.maricopa.edu/class/bio201/Histology/HistoR ev20a.htm http://www.gwc.maricopa.edu/class/bio201/Histology/HistoR ev20a.htm Picture from http://www.thechildrens hospital.org/wellness/inf o/kids/20169.aspx http://www.thechildrens hospital.org/wellness/inf o/kids/20169.aspx

8. Smooth Muscle 0 Can be found in your digestive system, circulatory system, and even the muscles in your eyes that help them to focus. 0 Smooth muscle tissue is located in the walls of hollow internal structures such as blood vessels, the stomach, intestines, and urinary bladder 0 Smooth muscle controls slow, involuntary movements such as the contraction of the smooth muscle tissue in the walls of the stomach and intestines. 0 The muscle of the arteries contracts and relaxes to regulate the blood pressure and the flow of blood. 0 Involuntary
