1. In embryology, one of the segments of the body wall or trunk musculature that develops from a somite.
Usage: technical; biology
2. In zoology, the dorsal or lateral portion of a somite that gives rise to skeletal muscles and connective tissue.
Usage: technical; zoology

Examples

• The epimere of each somite develops into the muscles of the back and sides.
• During vertebrate development, the epimere differentiates to form the axial musculature.
• Embryologists study the epimere to understand how body segmentation occurs.
• The epimere is distinct from the hypomere, which forms ventral muscles.
