myotome[′mī·ə‚tōm] (anatomy) A group of muscles innervated by a single spinal nerve. (embryology) The muscle plate that differentiates into myomeres. (engineering) An instrument used to divide a muscle. Myotome the rudimentary musculature in embryos of chor-date animals and man. The myotome is a paired metameric structure situated on the sides of the chorda and neural tube. It develops from the dorsal part of the internal wall of the somite. myotomeenUK
