Vesalius
Yes, Galen believed that the jawbone was made of two bones, which he discovered through the dissection of an animal. However this is incorrect as Vesalius later discovered through human dissection that humans only have one jawbone.
Andreas Vesalius is know today as the Founder of Human Anatomy. He was a physician to the Holy Roman Emperor Charles V and later to Phillip II of Spain. He wrote The Seven Books on the Structure of the Human Body which was the most accurate anatomy book at the time.

Because back in the middle ages it was illegal to disect humans.

Andreas Vesalius
Vesalius was faced with many difficulties, many people were against him and his work, one of these people was an english men named John Keys. Keys believed firmly in Galen's work and thought that Vesalius was wrong to disagree, for Keys, any mistakes in Galens work was due to translators, or copyists, and not by Galen himself. In addition Vesalius was asked to carry out a dissection in Bologna, and he broke the rules.He ignored the professors and the old men, he began a lecture of his own and invited students to gather around to see and even touch when they were not supposed to. Vesalius then brought a skeleton into the lecture room, he showed his students how muscles move the bones and so on, however the professor disagreed with him and said that these are not the opinions of Galen. Even Vesalius's old teacher, gunter von andernacht was against Vesalius and wrote the he should be punished by the emperor for the terrible things he was saying however Vesalius won! The emperor ignored Andernacht and appointed Vesalius as his physician.
Vesalius Discovered That The Jaw Was One Bone Not Two As Galen Had Said. That The Breast Was Made Up Of Three Bones Not Seven As Galen Had Said And That Blood Was Not Brought Into And Back Out Of The Heart Through Invisible Holes In The Septum And That In Fact It Was Brought In By The Veins And Back Out Through The Arteries
Andreas Vesalius's book "De humani corporis fabrica" was controversial because it challenged the teachings of Galen, a respected ancient Greek physician whose ideas had been followed for centuries. Vesalius's detailed anatomical observations contradicted many of Galen's claims, leading to significant backlash from traditionalists who were resistant to change in medical knowledge and practices. This marked a pivotal moment in the history of medicine, as it laid the groundwork for modern anatomical study and research.
not really people still thought galen was right about atanomy
To rise to the challenge is to accept the challenge
Andreas Vesalius (1514-64) was a Flemish anatomist. He made many discoveries in anatomy based on his studies involving the dissection of cadavers (human dead bodies).In 1543 Vesalius published the book De humani corporis fabrica (On the Workings of the Human Body), containing wonderful illustrations by Jan von Calcar, a pupil of the artist Titian.In this book Vesalius challenged the anatomical ideas of the anatomist Galen (2nd century AD), which had hitherto been uncritically accepted by doctors and anatomists. Vesalius showed that Galen's anatomy contained serious errors, as it was based on the study of the anatomy of animals (e.g. pigs) and not on a direct study of the anatomy of the human body
Yes, Galen believed that the jawbone was made of two bones, which he discovered through the dissection of an animal. However this is incorrect as Vesalius later discovered through human dissection that humans only have one jawbone.
Due to religious views, people did not believe in his ideas as they wanted to be faithful to God. People still believed in Galen's original theory of the four humours therefore Vesalius's seemed ridiculous and made no sense to them - they didn't want to believe it.
Andreas Vesalius' book on anatomy, De humani corporis fabrica libri septem (Seven Books on the Fabric of the Human Body) was published in 1543.He didn't discover anatomy, but his work challenged the views of human anatomy set forth by Galen 1300 years prior.
