Study Embryos
- Embryo 2W1, 3 mm in length (maximum).
- Embryo S1, 6 mm in length (maximum).
- Embryo B1, 8 mm in length (maximum).
- Embryo M1, 9 mm in length (maximum).
- Embryo S4, 12.5 mm in length (maximum).
- Embryo B2, 13 mm in length (maximum).
- Embryo 16 mm in length (maximum).
- Embryo S3, 20 mm in length (maximum).
- Embryo B3, 22 mm in length (maximum).
- Embryo 30 mm in length (maximum).
- Embryo E1, 28.5 mm in length (maximum).
All of these embryos showed good histological condition, and most of them almost perfect histological detail.
I am indebted to Prof. Symington for the embryos B1, B2, and B3, and to Prof. Peter Thompson and to Prof. Bryce respectively for the opportunity of examining and reconstructing from their sections the heart in the embryos 7 and 10 of the list.
