Myomere - Wikipedia

Myomeres are blocks of skeletal muscle tissue arranged in sequence, commonly found in aquatic chordates. Myomeres are separated from adjacent myomeres by fascia consisting of connective tissue, known as myosepta. Myomere counts are sometimes used for identifying specimens using meristics, since their number corresponds to the number of vertebrae in the adults. Myomere location varies, with some species containing these only near the tails, while some have them located near the scapular or pelvic girdles. Depending on the species, myomeres could be arranged in an epaxial or hypaxial manner; hypaxial refers to ventral muscles (those of the "stomach" region) and related structures, while epaxial refers to more dorsal muscles (those of the "back"). The horizontal septum divides these two regions in vertebrates from cyclostomes (jawless lamprey and hagfish) to gnathostomes (jawed fish). In terrestrial chordates, which are gnathostomes themselves, the myomeres become fused as well as indisti
