Location of major muscles

P3

» Research task:

In pairs Locate all major muscles on your

partner and be ready to know what each muscle is also known as & does.

The heart has its own muscle tissue called

Cardiac/ Myocardium muscle.

Function: the function of the myocardium is to pump blood around the body.

It beats minute

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.

Also an involuntary muscle as they are out of out

CONSCIOUS control. 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.

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).
