Fig. 6. Active twitch length–tension curve for the dl₁ muscles of Manduca (light solid line), mammalian cardiac muscle (heavy solid line; redrawn from Allen and Kentish, 1985), cat soleus muscle (light broken line; redrawn from Rack and Westbury, 1969) and the length–tension curve for tetanized cat soleus muscle (heavy broken line; redrawn from Rack and Westbury, 1969). Compared with mammalian skeletal muscle, the dl₁ muscles and mammalian cardiac muscle both have length–tension relationships with steep ascending regions and narrow peaks, even compared with mammalian skeletal muscle at low levels of activation. The curve for Manduca dl₁ muscles is the same as that shown for mechanically isolated muscles in Fig. 5C.
