Fig. 2From: The tymbal muscle of cicada has flight muscle-type sarcomeric architecture and protein expressionTypes of myofilament lattice of muscle. a 1:2 lattice (the myosin-to-actin filament number ratio is 1:2), seen in vertebrate skeletal and cardiac muscles. b 1:3 lattice, seen in insect flight muscles. c 1:5 lattice; d 1:6 lattice. These are seen in non-flight muscles of insects and in muscles of other arthropods. See also [19, 37]. The larger dots represent the myosin filaments, and the smaller dots, the actin filaments. The area marked by the lines represents the unit cell, which contains one myosin filamentBack to article page
