Hermann Amandus Schwarz. Robert Remak (26 July 1815 – 29 August 1865) was an embryologist, physiologist, and neurologist, born in Posen, Prussia, who discovered that the origin of cells was by the division of pre-existing cells. [1] as well as several other key discoveries.
Apr 3, 2024 · Robert Remak was a German embryologist and neurologist who discovered and named (1842) the three germ layers of the early embryo: the ectoderm, the mesoderm, and the endoderm. He also discovered nonmedullated nerve fibres (1838) and the nerve cells in the heart (1844) called Remak’s ganglia, and he.

Dec 20, 2002 · Contradicting Schwann, Remak placed animal cell division at the forefront of cell theory. In 1841, he described forms suggestive of cell division in red cell formation in the chick embryo. This was followed by an examination of muscle development in the tadpole and observations of the division of the fertilized chick ovum ( 7 ).

Abstract. After the first observations of life under the microscope, it took two centuries of research before the 'cell theory', the idea that all living things are composed of cells or their...
Robert Remak (1815-1865) was a pioneer of cell theory and embryology. He discovered nerve fibers, ganglion cells, and cell division, and reduced the four germ layers to three.
