Human Embryo Carnegie stage 11
Carnegie stage 11, 25 days, 19 somite pairs, 100 μm scale bar.
Scanning EM lateral view embryo fractured dorsally (box region) to show the neural crest and neural tube.
Head Region - Cranial neuropore open. Otic placode indenting on dorsal side behind the second pharyngeal arch. First pharyngeal arch lying below and beside the stomedeum.
Body Region - Ventral body wall removed to show pericardial cavity and heart tube. Yolk sac also removed to show midgut.
Carnegie stage 11: Week 4, 23 - 26 days, 2.5 - 4.5 mm, Somite Number 13 - 20
