Red muscle

      Less cross-striation and large number of mitochondria and myo-haemoglobin

      Contraction is slow but more sustained

      Examples: antigravity muscle of the trunk, brachialis, soleus 

 

White muscle

      More cross-striation and less number of mitochondria and myo-haemoglobin

      Contraction is rapid but less sustained

      Examples: biceps brachii
