Modifications of the mATPase technique by combinations of pH/time/molarity were carried out in order to compare the sensitivity of the myosin ATPase of each muscle fibre type of the lateral muscle. Results showed that the staining of muscle fibres was independent of small modifications in the technique. The intermediate 'pink' muscle was histochemically defined towards the end of the larval life and is considered to be implicated in the growth of the myotome. A layer of external cells was observed, by electron microscopical examination, between the connective tissue of the skin and the superficial red muscle fibres of larvae and postlarvae. It is suggested that the external cells are unlikely to be a source of red muscle fibres and implicated on the growth of the myotome, but rather a part of the dermatome. The timing, areas and mechanisms of hyperplastic growth of the myotome were defined and discussed.||URI:||http://hdl.handle.net/10553/47108||ISSN:||0340-2096||DOI:||10.1111/j.1439-0264.1998.tb00185.x||Source:||Anatomia, Histologia, Embryologia [ISSN 0340-2096], v. 27, p. 223-229|
