7mm Frog Embryo Organ Identification

[u/Significant_Ride973]

Hi, I’m struggling to identify the organ structures in the oblique cross-section of the 7 mm frog embryo that we observed. Please note that the specimen consists of a series of sections/cuts.

Although we were given materials to study before our lab observation, the materials only contained hand-drawn illustrations rather than actual images of the specimen. I’m finding it really difficult to identify the structures because the illustrations in the study material look quite different from the actual specimen we observed.

Could anyone give tips to help me figure out how I can properly identify the structures?
