EOG8Z6536 GO:0007517 1/93 muscle organ development biological_process "The process whose specific outcome is the progression of the muscle over time, from its formation to the mature structure. The muscle is an organ consisting of a tissue made up of various elongated cells that are specialized to contract and thus to produce movement and mechanical work."

The anterior-posterior axis is defined by a line that runs from the head or mouth of an organism to the tail or opposite end of the organism."
