Gilbert Breschet

Gilbert Breschet (July 7, 1784 - May 10, 1845) was a French anatomist who was born in Clermont-Ferrand. He studied medicine at the University of Paris, and in 1812 was conferred as doctor of medicine in Paris. In 1836 he succeeded Jean Cruveilhier (1791-1874) as professor of anatomy at the Faculté de médecine de Paris.

Breschet made many contributions in comparative anatomy and research of zoonotic diseases. In 1813 with François Magendie (1783-1855) he demonstrated that rabies can be transmitted from the saliva of humans to dogs. He also discovered the rete mirabile in whales and dolphins, which is a vascular network that allows these mammals to survive and adapt at ocean depths.

He did extensive anatomical studies of veins of the cranium and spine, and made important investigations of the auditory system in vertebrates. He provided a comprehensive description of the utricle and saccule of the inner ear, and is credited for introducing the terms otoconia and helicotrema. The helicotrema is sometimes referred to as "Breschet's hiatus", which is an passageway that connects the scala tympani and scala vestibuli at the top of the cochlea. Breschet has several other anatomical terms named after him, including:

• Breschet's bone(s): Small ossicles occasionally found in the ligaments of the sternoclavicular articulation. Also known as "os suprasternale" or as an episternal bone.
• Breschet's canals: (canales diploici), Channels in the diploe of the skull that accommodate the diploic veins.
• Breschet's sinus: Also known as the sphenoparietal sinus.
• Breschet's veins: (venae diploici), Diploic veins connected with the cerebral sinuses by emissary veins.
