Therefore they variety the body wall as well as limbs—much the weightier part of the body. They offer the segmental character to the body wall in neck and trunk, and, adhering to their lead, the spinal wire gets to be correspondingly segmented. The ventral mesoderm is not so extensive; it remains near the alimentary tube and becomes the continual muscle layer of your tummy and intestine. In addition it kinds the lining in the body cavities, The graceful, shining, slippery pleura and peritoneum.
