Bella Symptom

Bella Symptom (1774-1842) - an outstanding Scottish anatomist, physiologist and surgeon.

He was born in Scotland in 1774. Symptom showed great interest in medicine from an early age. After graduating from the University of Edinburgh, he devoted himself to studying the anatomy and physiology of the human body.

The symptom has made a significant contribution to the understanding of the functioning of the nervous system and sensory organs. He described in detail the structure of the eye and ear, as well as the pathways from these organs to the brain.

In addition to scientific activities, Symptom was engaged in practical surgery. He improved many surgical techniques and developed new instruments.

The symptom left behind fundamental works on anatomy and physiology, which served as the basis for further research in these areas. He is considered one of the founders of modern neuroscience.

Bella Symptom died in 1842 at the age of 68, leaving an indelible mark on the history of medicine.



Bell's sign is one of the key terms of anatomy, introduced by the Scottish scientist Charles Bell in 1825. This symptom was described by Bell as an abnormality of certain arteries that were outside the boundaries of a normal artery. Noted in the analysis of blood vessels (including arterial ones) "exclusively in women - incoherent blockage" was then classified as a disease in 1906 by George Laney. Belle moved from surgery to anatomy to observe the changes in the arteries of cadavers throughout their life course. He discovered that many arteries change in size and shape at different times in life, and that the changes may be related to changes in gender.

Bell was best known for his research on the female heart. He made an important insight when he stated that a woman's heart can have two circuits of blood circulation, causing the left side of the heart to beat and contract in the opposite direction to the right side of the heart. His theory of two circuits of blood circulation found support in some other works, but other medical professionals ridiculed his theory, calling it unscientific nonsense. As a result, Bell said he was willing to give up his doctorate, but his theory "remains true." There are several important moments in the life of physician Charles Bell. Bell's main "scientific starting point" lies in his observation of the presence of a male heart in female fetuses born simultaneously from the same presentation, which he made while practicing as a doctor in Westminster. While working in an experimental laboratory, Bell received an impetus to study anatomy and prescribed for himself: “to be only an observer.” From Bell's earliest monographs it follows that he observed ligations of two large round arteries in premature female defects, when the arteries branched after the right atrium. But it was his work on the development of the female heart that subsequently led researchers to a better understanding of the origin of the double circulation. Observing the opening of the pulmonary veins and umbilical arteries and having some knowledge, as far as possible, about the circulation of blood in the human body, Bello came to the conclusion that there was a left independent circle, starting with the pulmonary vein. Neither before nor after him had anyone examined the pulmonary veins and left-sided pulmonary artery as systematically as Bell did (Bell 1813). In Bello's previous work, On the Organ of Generation and its Appendant Circulatory System, Bello described the workings of this circulation in terms of four hearts, consisting of single-chambered left ("left" and "right") hearts. This meant that Bell paved the way for the most common hypothesis, speaking about the origin of the double circle: it was later proposed by Karl Bruno (63 years before



Bella's symptom is a scientific term that refers to a physical therapy procedure used to treat patients with symptoms of sciatica. This medical maneuver is also known as a recumbent roll or a Bird roll. Bella's sign can help reduce pain and improve the patient's mobility. But remember that before using this procedure, you must consult your doctor and make sure there are no contraindications.
