1 Congress Middle School Pre-Medical Magnet Program 2008 Presented by: Diana Herec, Medical Magnet Coordinator

2 Human Anatomy & Physiology The Muscular System

3 Responsible for bodily movement Includes the voluntary muscles of the body About 700 muscles in the human body Vary greatly in size

4 Muscle Action Muscle action depends on its position with the joint it works on Limb movement requires the teamwork of several muscles Muscles contract when activated

5 Muscle Contraction If the force of a muscle contraction is greater than the force resisting it, the contraction is known as Isotonic Contraction

6 muscle contraction continued… If resistance to contraction is equal to the force, the muscle will not contract, known as: Isometric Contraction

7 Skeletal Muscle Most prominent type of muscle in the body May account for up to 60% body mass It is attached to bones at both ends by tendons

8 Skeletal Muscle continued… Skeletal muscle is under constant control, therefore, known as: Voluntary Muscle

9 Just below the surface of the skin The muscles and skeleton are responsible for an individuals Physique

10 Muscle Types Classified by shape: Parallel fibers Oblique fibers Shape and arrangement of fibers reflect muscle function

11 Pennate Muscles Have feather-like appearance and fibers run obliquely down to the tendon

12 Some spiral muscles have the capacity to turn half a rotation between their attachments

13 Others twist around a bone

14 In the common spindle-shaped muscles, all fibers run from one tendon to another

15 Circular Muscles Fibers of circular muscles are arranged in concentric circles

16 Muscles consist of bundles of fibers that can be organized in different ways, according to the function of the muscle
