Location of major muscles

1. P3 Location of major muscles

2. Research task: In pairs Locate all major muscles on your partner and be ready to know what each muscle is also known as & does. biceps triceps deltoids pectorals rectus abdominus quadriceps. These must be split into: o rectus femoris o vastuslateralis o vastusmedialis o vastusintermedius) hamstrings. These must split into: · semimembranosus · semitendinosus · biceps femoris gastrocnemius soleus tibialis anterior erector spinae teres major trapezius latissimusdorsi obliques gluteus maximus Muscular system

3. Lower body: • Anterior view • Quadriceps: • Rectus Femoris • vastusIntermedius • VastusLateralis • VastusMedialis Tibialis anterior Muscular system

4. Posterior View (back) • Lower body Gluteus Maximus • Hamstrings: • Semimembranosus • Semitendinosus • Biceps Femoris Gastrocnemius Soleus Muscular System

5. Upper body anterior view Biceps Triceps Deltoids Pectoralis Major Rectus Abdominus Obliques Muscular System

6. Upper body posterior view Teres Major Trapezius- Upper back LatisimusDorsi- Lower Back Erector spinae Muscular System

7. Copy and complete the tables…

8. There arethree types of muscle; • Cardiac- in-voluntary the muscle that encompass the heart • Smooth- in-voluntary • Skeletal- voluntary Provides Human Movement, attached to the skeleton by tendons Divide the class into 3 (Cardiac/Smooth and Skeletal muscle): - Find a couple of images of the muscle - Say what this type of muscle does - Give a few examples Muscles Be prepared to feedback your findings to the class…

9. The heart has its own muscle tissue called Cardiac/ Myocardium muscle. It is an Involuntary muscle: as it has its own nerve supply. It works by sending nerve impulses through the cells and fibres within the muscle. Function: the function of the myocardium is to pump blood around the body. It beats 60-80 times a minute Cardiac Muscle

10. Also an involuntary muscle as they are out of out CONSCIOUScontrol. Found in the digestive system (large and small intestine), Circulatory system (artery and vein walls) and Urinary system. Smooth muscle contracts consecutively (peristaltic action), producing a wavelike effect. E.G. when food is passed through the digestive system it is slowly squeezed through the intestines. Smooth Muscle

11. Muscle that is attached to the skeleton across joints… It is under voluntary control as we decide when to contract the muscles and produce movement. • Skeletal muscle is responsible for the following functions: • Produce movement • Maintaining body posture • Generate heat for warmth • What else? Co-ordinated contractions of the skeletal muscle allow us to move smoothly and produce sports skills. Skeletal Muscle Over 700 skeletal muscles make up 40% of our body weight (slightly less for females).

12. Major muscles: • Biceps • Triceps • Deltoids • Pectoralis major • Rectus abdominis • Thigh Muscles: Rectus femoris, vastuslateralis, vastusmedialis, vastusintermedius, semimembranosus, semitendinosus, biceps femoris • Gastrocnemius • Soleus • Tibialis anterior • Erector spinae • Teres major • Trapezius • Latissimusdorsi • Obliques • Gluteus maximus For P3, identify the location of the named muscles (across) Including the three types of muscle. Types of muscle: Cardiac, Skeletal, Smooth
