The Muscular System  Chapter 15  Title (Content Area): Integumentary, Skeletal, and Muscular Systems  Lesson3  Title (Topic): The Muscular System  Grade Level: Seventh grade

The Muscular System Objectives:  Knowledge: The students will be able to: 1. Define structure and function of muscles. 2. List six large muscle groups. 3. Illustrate the two problems of the Muscular System. 4. Describe four Injury-Related Muscular Problems.

The Muscular System Objectives:  Attitude: The students will be able to: 1. Have a feeling of empowerment by having the knowledge /skills for preventing and first-aiding muscle injuries. 2. Identify muscle injuries and what treatment is needed. 3. Identify ways to care for muscles

The Muscular System Objectives:  Practice: The students will be able to: 1. Analyze situations determining which group of muscle in injured. 2. Determine the injury type and apply the treatment.

The Muscular System Part 1: Structure of Muscular System Part 2: Type of Muscles Part 3: Large Muscle Groups Part 4: Care of the Muscular System Part 5: Problems of Muscular System Part 6: Injury-Related Muscular Problems

Structure of Muscular System 1. Myofibrils 2. actin and myosin

Type of Muscles 1. smooth muscle. 2. skeletal muscle. 3. cardiac muscle

Large Muscle Groups 1. Biceps 2. Triceps 3. Deltoid

Large Muscle Groups 4. Quadriceps 5. Abductor muscles (pull legs away from body) 6. Adductor muscles (pull legs toward body)

Care of the Muscular System 1. Warm-up & cool down. 2. Appropriate clothing

Problems of Muscular System 1. Myasthenia Gravis. 2. Muscular Dystrophy.

Injury-Related Muscular Problems 1. Muscle strain – “pulled muscle” is a tearing or stretching of muscle fibers as a result of suddenly pulling them too far. Treatment consists of Rest, Ice, Compress, and Elevation (R.I.C.E). 2. Bruise – discolored area under the skin caused by leakage of blood after injury. Ice or a cold pack can reduce the pain and swelling of a large bruise.

Injury-Related Muscular Problems 3. Tendinitis – the inflammation of a tendon, usually caused by overuse. Treatment may include anti-inflammatory medications, ultrasound, or injection of corticosteroids. 4. Hernia – one of more serious muscle injuries, which is protrusion of an organ or tissue through a weak area in the muscle. Surgery is usually required to repair a hernia.
