Embryo Surface Carnegie Stage 23

This movie shows an unlabeled MRI 3D volume embryo surface scan around the Kyoto embryo (stage 23, week 8).


Note:

  • Size of head relative to trunk.
  • Position and size of limbs.
  • Herniated midgut outside ventral body wall.

Central Nervous System

This movie shows a MRI 3D volume scan inside the Kyoto embryo (stage 23, week 8).

The labelled sagittal head section movie show further detail.


Note:

  • Surface size and position of the CNS within the embryo.
  • Growth of the cortex (telencephalon)
  • Neural flexures forming large IV ventricular space.

Midgut Herniation

This movie shows an extract from the whole embryo sagittal MRI scan (left to right) through a Kyoto embryo (stage 23, week 8).

The extracted region shows the midgut (intestines) lie outside the ventral body wall (midgut herniation) at the end of the embryonic period.

This herniation will not be lost until the early fetal period.

Abnormalities can arise from either abnormal body wall development or from gastrointestinal tract development.
