Description:
Development of the heart from the first and second heart fields. a) The cardiac crescent contains both first heart field (FHF) and second heart field (SHF) precursors. b) In a later stage, the still undivided heart with an atrial component with the cardinal veins and the pulmonary vein. The ventricular compartment shows anterior (future right) and posterior (future left) sides. The cardiac jelly has developed into two cushion complexes: the atrioventricular and outflow tract cushions (blue). The arterial pole shows the aortic sac and with the attached pharyngeal arch arteries. The dorsal mesocardium starts to disrupt (brown hole). The second heart field is depicted in yellow. c) The derivatives of the anterior and posterior parts of the second heart field (yellow) together with the migrated neural crest cells (blue-green). DAo, dorsal aorta; FHF, first heart field; PAA, pharyngeal arch arteries; SHF, second heart field. Description adapted from Poelmann RE, Gittenberger-de Groot AC. Development and evolution of the metazoan heart. Dev Dyn. 2019 Aug;248(8):634-656 (CC BY). Version without labels
