Tissue Development
Abdominal Wall Muscle
Carnegie stage 19 (E48) Segregation of the myoblasts into four distinct muscle groups was evident by CS 19 with unidirectional orientation of myoblasts. The myoblasts migrated over half of the distance to the ventral midline. The abdominal wall remains thickest in the area where the muscles migrated and again the outermost layer of connective tissue comprises approximately half of the total thickness of the abdominal wall in this region. In contrast the primary abdominal wall that is ventral to the migrating myoblasts was noticeably thinner. Unlike the mouse where the rectus is not segregated from the other muscles until reaching the midline, the human rectus was completely separated after migrating over half the distance to the midline.
