somitomeric trunk muscle development The process whose specific outcome is the progression of the somitomeric trunk muscle over time, from its formation to the mature structure. The somitomeric trunk muscle is derived from somitomeric mesoderm. The muscle begins its development with the differentiation of the muscle cells and ends with the mature muscle. An example of this process is found in Mus musculus. GO:0002075 biological_process skeletal muscle organ development
