Other names: EHDAA2, Human Developmental Anatomy Ontology, abstract version 2
The EHDAA2 ontology is a human developmental anatomy covering the first 49 days [Carnegie stages (CS)1–20], primarily structured around the parts of organ systems and their development. The ontology includes more than 2000 anatomical entities (AEs) that range from the whole embryo, through organ systems and organ parts down to simple or leaf tissues (groups of cells with the same morphological phenotype), as well as features such as cavities. It represents a complete rebuilding of the EHDA intended to meet current standards. The intention has been to include as much information about human developmental anatomy as is practical and as is available in the literature.
