Development of the Nervous System
Image 50 - 56: Midbrain and hindbrain. The isthmus can be observed on 52 - 53 as a constriction between the mid- and hind-brain. The hindbrain is already subdivided into two parts, the slim myelencephalon and the wider metencephalon. The boundary between these two parts is roughly at the level of the otic vesicles 3 - 4. Identify the optic cup and stalk, which are derived from the forebrain 58 - 62. Caudally one can identify the spinal cord along the entire length of the embryo.

About Stage 13 Embryo Sections - This image is from a serial section of a 6mm CRL pig embryo with some features of the Stage 14 embryo. This embryo is approximately equal to the day 42 human embryo. Use these serial images to identify internal features and relationships that exist within the embryo at this stage. Then compare these images with the later features of the Carnegie stage 22 human embryo.
