8 Muscles There are three types of muscle; Cardiac- in-voluntary the muscle that encompass the heartSmooth- in-voluntarySkeletal- voluntary Provides Human Movement, attached to the skeleton by tendonsDivide 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 examplesMusclesBe prepared to feedback your findings to the class…
9 The heart has its own muscle tissue called Cardiac/ Myocardium muscle.Cardiac MuscleIt 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 times a minute
10 Also an involuntary muscle as they are out of out CONSCIOUS control. Smooth MuscleFound 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.
11 Skeletal MuscleMuscle 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 movementMaintaining body postureGenerate heat for warmthWhat 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).
