Location of major muscles P3

Muscular system 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 vastus lateralis o vastus medialis o vastus intermedius) hamstrings. These must split into: · semimembranosus · semitendinosus · biceps femoris gastrocnemius soleus tibialis anterior erector spinae teres major trapezius latissimus dorsi obliques gluteus maximus

Muscles There are three 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…

The heart has its own muscle tissue called Cardiac/ Myocardium muscle. Cardiac 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

Also an involuntary muscle as they are out of out CONSCIOUS control. Smooth Muscle 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.

Skeletal Muscle 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. Over 700 skeletal muscles make up 40% of our body weight (slightly less for females).
