Hi, my name is Marjolaine. This is what I have learnt so far in e-tasc:When your biceps contract your triceps relax. Did you know,that when you eat lunch you use these muscles:Triceps, biceps, jaw muscle and your oesophagus. Muscles connect to bones and joints. Muscles need a supply of oxygen to work properly. When you exercise, your muscles contract and extend. The skeleton is covered by more than 600 muscles which enable the body to move. When you want to move, your brain sends a message to your muscles.
