These movies shows the appearance of human embryo during week 6 Carnegie stage 16 (GA week 8).

Embryo Surface - Carnegie Stage 16

This movie shows an unlabeled MRI 3D volume embryo scan of the Kyoto embryo (stage 16, week 6). Compare this with the earlier stage 13 week 4 embryo.

Note:

  • Growth of limb buds
  • Size of the head
  • Pharyngeal arches
  • Size and position of the heart
  • Umbilicus containing cord with placental blood vessels

Neural Development

This labelled version shows the Stage 16 embryo rotating with the CNS spinal cord and the secondary brain vesicles and flexures labeled.

Note:

  • Growth of limb buds.
  • Development of the vision and hearing sensory vesicles (optic and otic) and their relative positions (optic at the diencephalon; otic at the metencephalon).
  • The lamina terminalis at the end of the neural tube (site of cranial/anterior neuropore closure).
  • The 5 secondary brain vesicles.
  • The large ventricular space within the tube, divided into future regions.
  • The lateral walls of the neural tube forming alar and basal plates (particularly obvious along spinal cord).
  • The top and bottom of the neural tube forming thin roof and floor plates (particularly obvious along spinal cord).
  • The large dorsal root ganglia along the length of the spinal cord.
  • The 3 brain flexures; cephalic (or mesencephalic), pontine and cervical.

Sagittal Sections

This movie shows an unlabeled MRI sagittal scan passing from right to left through the Kyoto embryo (stage 16, week 6). Compare this with the earlier stage 13 week 4 embryo CNS.

Note:

  • Growth of limb buds.
  • Development of the vision and hearing sensory vesicles (optic and otic) and their relative positions (optic at the diencephalon; otic at the metencephalon).
  • The lamina terminalis at the end of the neural tube (site of cranial/anterior neuropore closure).
  • The 5 secondary brain vesicles.
  • The large ventricular space within the tube, divided into future regions.
  • The lateral walls of the neural tube forming alar and basal plates (particularly obvious along spinal cord).
  • The top and bottom of the neural tube forming thin roof and floor plates (particularly obvious along spinal cord).
  • The large dorsal root ganglia along the length of the spinal cord.
  • The 3 brain flexures; cephalic (or mesencephalic), pontine and cervical.
