Myomeric segmentation
WebApr 15, 2024 · Lancelets have a distinct coelom or body cavity which forms a system of cavities and spaces (Ghiselin, 2008). On the other hand, tunicates do not develop a very distinct body coelom. Moreover, lancelets …
Myomeric segmentation
Did you know?
Myomeres are blocks of skeletal muscle tissue arranged in sequence, commonly found in aquatic chordates. Myomeres are separated from adjacent myomeres by connective fascia (myosepta) and most easily seen in larval fishes or in the olm. Myomere counts are sometimes used for identifying specimens, … See more The shape of myomeres varies by species. Myomeres are commonly zig-zag, "V" (lancelets), "W" (fishes), or straight (tetrapods)– shaped muscle fibers. Generally, cyclostome myomeres are arranged in vertical … See more Fossils Published information on Pikaia gracilens (a well-known Cambrian era fossil) explains evolution of swimming ability in chordates related to myomere shape and function. Specifically, myomeres in this species possessed … See more Specifically, three types of myomeres in fish-like chordates include amphioxine (lancelet), cyclostomine (jawless fish), and gnathostomine (jawed fish). A common function shared by all of these is that they function to flex the body laterally into concavity to provide … See more http://diswww.mit.edu/bloom-picayune.mit.edu/sipb-afs/208923
