A transverse section. through a bundle of such fibres shows, therefore, their cross sections irregular in shape and size. (4) Each nucleus of a muscle corpuscle occupies the centre of one prismatic portion; each fibre and its branches thus appear composed of a single row of such prismatic portions, and they seem separated from one another —at any rate in an early stage—by a septum of a transparent substance. 93. Muscular fibres seem either markedly pale or markedly red (Ranvier); in the former {, quadratus lumborum, or adductor magnus femoris of rabbit) the transverse striation is more distinct and the muscular corpuscles less numerous, than in the latter {, semi-tendinosus of rabbit,.
