Riassunto

Excerpt from A Laboratory Manual and Text-Book of Embryology

The study of human embryology deals with the development of the individual from the origin of the germ cells to the adult condition. To the medical student human embryology is of primary importance because it affords a comprehensive understanding of gross anatomy. It is on this account that only recently a prominent surgeon has recommended a thorough study of embryology as one of the foundation stones of surgical training. Embryology not only throws light on the normal anatomy of the adult, but it also explains the occurrence of many anomalies and mon sters, and the origin of certain pathological changes in the tissues. Obstet rics is essentially applied embryology. From the theoretical Side, em bryology is the key with which we may unlock the secrets of heredity, the determination of sex, and, in part, of organic evolution.

There is, unfortunately, a View current among graduates in medicine that the field of embryology has been fully reaped and gleaned of its harvest. On the contrary, much productive ground is as yet unworked, and all well-preserved human embryos are of value to the investigator. Only through the co-operation of Clinicians in collecting and preserving embryos will our ignorance of early human development be rectified. At present, practically nothing is known of the maturing ovum, while of fertilization, cleavage, and the formation of the germ layers we are en tirely in the dark. Aborted embryos and those obtained by operation in case of either normal or ectopic pregnancies should always be saved and pre served at once by immersing them intact in IO per cent formalin or in Zenker's fluid.
