Image Features

Gastrointestinal Development

Stomach and lesser sac in mesentery. Triangular flange of mesentery with triangular hole and intervitelline anastomosis. Hindgut (without lumen) seen at caudal end of mesentery.

Neural Development

Musculoskeletal Development

Cervical region: dark masses of dorsal root ganglia. Lumbar region: dorsal aorta with its dorsal segmental arterial branches. Between each dorsal segmental artery is a darker-staining mass of mesenchyme (the dark part of a sclerotome) which is the anlage of the intervertebral disc. The dorsal segmental artery itself marks the location of the centre of the light-staining part of the sclerotome, which is the future vertebral body. The dark band dorsal to the sclerotomes is the basal lamina of the wall of the neural tube.
