Introduction

Mark Hill.jpg

This page shows the brief historic vignettes that appear on various notes pages introduction and other sections. These are intended to give some historic background to Embryology. These can also appear as a collapsible table.

The links shown below are to full versions of historic embryology textbooks and papers.

Historic Disclaimer - information about historic embryology pages 
Mark Hill.jpg
Pages where the terms "Historic" (textbooks, papers, people, recommendations) appear on this site, and sections within pages where this disclaimer appears, indicate that the content and scientific understanding are specific to the time of publication. This means that while some scientific descriptions are still accurate, the terminology and interpretation of the developmental mechanisms reflect the understanding at the time of original publication and those of the preceding periods, these terms, interpretations and recommendations may not reflect our current scientific understanding.     (More?

Cerebellum

Historic Embryology
Santiago Ramón y Cajal
Much of the basic structure of the cerebellum comes the historic histological studies and staining of Ramón Cahal (1852 - 1934) and Camillo Golgi (1843 - 1926). Cahal was a Spanish researcher who used the then new histology Golgi staining techniques to identify the cerebellum cellular structure. His work was a turning point in our understanding of the structure of the brain, that until then had been described as a "syncytium" and not consisting of discrete cellular elements. For this research and other work on defining the structure of the brain he, along with Camillo Golgi (1843 - 1926), received the 1906 Nobel Prize in Medicine.

Camillo Golgi (1843 - 1926) developed the histology silver staining technique, though is best known today for the cellular organelle that bears his name, the Golgi apparatus.

Ductus Deferens

Historic Embryology
Caspar Friedrich Wolff (1734-1794)
Theoria Generationis 1774.jpg

Caspar Friedrich Wolff (1734-1794) was a German embryologist and anatomist best known today for identifying the Wolffian duct (mesonephric duct; ductus deferens, epididymis), Wolffian body (mesonephros) and Wolffian cyst (mesonephric origin uterine broad ligament cyst) that bear his name. Thought also to be a founder of the germ layer theory. His doctorate dissertation Theoria generationis (1774) discarded the developmental theory of preformation. Later in his career, his teaching in Berlin was opposed by the professors of the Medical-Surgical College, who had guild privileges to teach medicine.

Neural Crest

Historic Embryology
Arthur Milnes Marshall.jpg
Wilhelm His.jpg

Arthur Milnes Marshall (1852–1893) at Cambridge in 1879 historically first described this embryonic region. In his study of dogfish and chicken brain development, and identified it as "neural crest".[1] See neural crest history and the original 1879 article. Wilhelm His (1831-1904) in 1868 also described in the chick embryo the early neural structure that would form neural crest.

Ovary

Historic Embryology
Nelsen1953 fig001.jpg
Meyer1932history3 fig02.jpg
Regnier de Graaf (1641 – 1673) was a Dutch anatomist and physician who described the anatomy of the uterine tube and the development of follicles in the ovary. He was first to describe the "Graafian follicle" (preovulatory follicle) in the ovary of mammals, but erroneously believed the entire follicle to be the mammalian oocyte (egg).

Pituitary

Historic Embryology
Martin Heinrich Rathke (1793 – 1860)
During pituitary development, the boundary surface ectoderm placode epithelium on the roof of the pharynx forms a transient epithelial pocket (Rathke's pouch) that comes into contact with the ectoderm of developing brain.


Rathke's pouch is named after the German embryologist and anatomist Martin Heinrich Rathke (1793 -1860).

Uterus

Historic Embryology
Johannes Muller.jpg
Johannes Peter Müller (1801 - 1858) in 1830 was the first to describe the female genital duct that develops as the uterus and vagina, historically named after him as the "Müllerian duct". The current terminology is the "paramesonephric duct".
