His comprehensive works on the fine structure and forms of tumors are well-known. Here he stated the principle, not before recognized, that the kind of sensation following stimulation of a sensory nerve does not depend on the mode of stimulation but upon the nature of the sense organ. His first important works, Zur vergleichenden Physiologie des Gesichtsinns (“On the comparative physiology of sight,” Leipzig, 1826) and Über die phantastischen Gesichtserscheinungen (“On visual hallucination,” Coblenz, 1826), are of a subjective philosophical tendency.
It manifests Müller’s interests in vitalism, philosophy and scientific rigor. The first work concerns the most important facts as to human and animal sight, the second sounds depths of difficult psychological problems. Entered by André Ferreira, 9 Sep 2022

It may be possible to confirm family relationships.He made valuable observations on the visual organs and the sympathetic nervous system of invertebrates and conducted research on the classification of fish, amphibians, and birds.
In the field of sensory organ physiology, Müller adhered to the concept of "specific energy," which posited that sensations experienced by humans when perceiving the external world are not reflective of objective reality but rather manifestations of the internal properties of the sense organs themselves.
He considers in detail various physiological systems of a wide variety of animals, but attributes the indivisible whole of an organism to the presence of a soul. 13. He authored the renowned textbook "Handbuch der Physiologie des Menschen" (Handbook of Human Physiology) from 1834 to 1840, which went through several editions.
His contributions to the fields of physiology, comparative anatomy, and embryology have had a lasting impact on the scientific community and continue to be studied and appreciated to this day.

He was the son of a poor shoemaker, and was about to be apprenticed to a saddler when his talents attracted the attention of his teacher, and he prepared himself for the Roman Catholic priesthood.When he was 18 though, his love for natural science became dominant, and he turned to medicine, entering the University of Bonn in 1819.

in his A History of British Starfishes, and Other Animals of the Class Echinodermata (1841) in his preface refers to Muller as the “one of the greatest living physiologists, Muller of Berlin”.
Müller mentored such distinguished scientists and physiologists as Hermann von Helmholtz, Emil du Bois-Reymond, Theodor Schwann, Friedrich Gustav Jakob Henle, Carl Ludwig and Ernst Haeckel.
Müller died in Berlin in 1858.
However, the inadequacy of these views was demonstrated by the works of the Russian physiologist I.M. Sechenov.
Müller extensively utilized the microscope in his research. Müller was also the first to attempt a classification of neoplasms based on the comparison of tumor structure and development.
Notable Achievements
Müller provided detailed descriptions of the human embryo at early stages of development, investigated the process of embryonic respiration, and discovered the embryonic ducts that were later named "Müllerian ducts" in his honor.

He discusses the difference between inorganic and organic matter. In 1833 he went to the Humboldt University of Berlin, where he filled the chair of anatomy and physiology until his death.
Müller made contributions in numerous domains of physiology, in particular increasing understanding of the voice, speech and hearing, as well as the chemical and physical properties of lymph, chyle and blood.
In it, for the first time, the results of human and comparative anatomy, as well as of chemistry and other departments of physical science, and tools like the microscope, were brought to bear on the investigation of physiological problems.
The most important portion of the work was that dealing with nervous action and the mechanism of the senses.
