During this time the estimated total number of muscle cells in the body increases from approximately 600 to 21 000 cells. This non-eutelic development appears to occur by division of platymyarian muscle cells into coelomyarian cells, thereby increasing the number of muscle cells\/quadrant from 5 to 85. The incompleteness of these divisions results in sarcoplasmic connections among muscle cells, and between muscle cells and nerve chords. At 11 days p.i., immediately after the 3rd moult, the variation in muscle cell length in a quadrant, with the longest cells being at the lateral chords, has been established. The average muscle cell length at this point is 0\u00b7101 mm, the longest is 0\u00b7164 mm. These values have increased to 0\u00b7365 mm and 1\u00b7122 mm, respectively, by 22 days p.i. At 18 days p.i. those cells in the posterior section of the larva are still the shortest in the body.<\/jats:p>","DOI":"10.1017\/s003118200005441x","type":"journal-article","created":{"date-parts":[[2009,6,5]],"date-time":"2009-06-05T16:31:34Z","timestamp":1244219494000},"page":"141-151","source":"Crossref","is-referenced-by-count":3,"title":["Changes in the somatic musculature of the 4th-stage larvae of<i>Ascaris suum<\/i>Goeze, 1782 (Nematoda: Ascaridoidea) developing in swine"],"prefix":"10.1017","volume":"88","author":[{"given":"R.
