Solution Grenouille Posted October 8, 2021 Solution Share Posted October 8, 2021 salut Alors un costamere est une structure au niveau de ta membrane qui va permettre l'ancrage des myofibrilles au sarcolemme. Ce point d'ancrage se retrouve en regard des stries Z ce qui permet un bon alignement des myofibrilles. Un sarcomere est l'intervalle qui existe entre 2 stries Z. (c'est l'unité contractile de ton muscle) est-ce que c'est plus clair? Quote Link to comment Share on other sites More sharing options...
