What is the ligamentum arteriosum?
Arteriosum ligamentum is a piece of fibrous tissue that develops from Ductus arteriosus (DA). It is shaped within three weeks of the birth of a person and remains a feature in a normal adult heart. The term ligamentum arteriosum is a Latin phrase for arterial ligament.
Some people describe the ligamentum arteriosum as a broken bit ductus arteriosus after embryonic work. Others, however, quote the remnant as contributing to the rupture of the aorta - the largest artery of the body - during the main trauma. This is because it keeps the artery in its place when it stems back to its original position during rapid slowing. As a result, the aorta can open.
During prenatal development, the heart of the fetus has a small hole or a passage called ductus arteriosus. It is also called Ductus Botalli, connecting the pulmonary artery that transports deogygenated blood from the heart to the lungs and the aorta area, referered it as an aortic arch. In the fetal, howeverfilled with liquid.
, within 12 to 24 hours after birth, however, the DA begins to close - a process that is usually completed within three weeks. Ligamentum Arteriosum is what remains after this closure and is associated with an aortic arch and pulmonary artery. The pulmonary artery is located to the area of the arterial ligament or the lower center. The aortic arch is a posterosuperior to the ligament or is located on the back and above.
Lateral to ligamentum arteriosum is a vagus nerve, which is 10. of 12 pair of skull nerves. For this reason, it is also called the cranial nerve X. Also the side to the vestige is the recurrent larynx or galen's nerve that springs the naagus nerve left. The larynx hooks around the ligaments from the back, where there is a part of the aorta, then goes up into the voice cabinet on which it is called.
in advance or frontal is the ligamentum arteriosum near the surface of the nerve network that innervates the heart from its base. TanGLE is called heart plexus. On the front of the arteriosum ligamentum is also a French nerve, which is mainly based on the fourth uterine nerve (C4).
