1 Get Out Your Vocab for the Muscular System

2 Vocabulary Quiz Define the following terms on a separate piece of paper – Elastic – Contract – Voluntary – Involuntary – Axis

3 Muscular System What does it do? – Makes all movements possible Move all body parts Heart beat Breathing Digestion

4 Muscular System What are the main functions? – produce heat Shivering – muscles rubbing together – Produce movement Writing, breathing – Maintain posture Sitting up straight

5 Muscular System What are the types of muscle? – Voluntary  you contract when you want to move (skeletal muscle). Movement is not automatic – Involuntary  contract automatically (stomach, intestines, heart) movement is automatic….you cannot tell your heart or stomach to stop

6 Muscular System What are tendons? – Connect muscle to bone – When a muscle contracts the tendon moves the bone – Why not just connect muscle to bone?? Tendons are stronger and take the pressure off the muscle so you are less likely to tear a muscle

7 Muscular System What are the types of muscle tissue? – Skeletal/ Striated  voluntary, provide movement of the body – Visceral/Smooth  involuntary, form the walls of the internal organs of the body (digestive tract, respiratory passages, walls of blood vessels) – Cardiac  involuntary, forms the walls of the heart

8 Muscular System What are the basic movements of skeletal muscle? – Adduct: moving a body part toward the midline of the body – Abduct: moving a body part away from the midline of the body – Extend: straightening a body part or moving it away from the body – Flex: bending a body part toward the body – Rotate: turning a body part on its axis – Open and close openings: sphincters, like the urethra or esophagus

9 Muscular System What are the basic movements of skeletal muscle? – Supinate: turn palm of the hand upward medially, sole of the foot upward medially, or lie facing upward (supine) – Pronate: turn palm of the hand downward medially, sole of the foot downward medially, lie facing downward (prone)

10 Muscular System What are the basic movements of skeletal muscle? – Inversion: turn the sole of the foot inward so that the medial border of the foot is elevated – Eversion: turn the sole of the foot outward so that the lateral border of the foot is elevated

11 Skeletal Muscles- Anterior View

12 Skeletal Muscles- Posterior View
