What is the difference between somebody with Type-I Diabetes vs. Type II Diabetes?
Type I Diabetes is also known as "Insulin-Dependent Diabetes", because in the case of individuals that have this condition, their Beta cells are unable to create insulin as they are supposed to. This is why individuals with Type-I Diabetes have to receive Insulin injections for treatment. Type II Diabetes is also called "Insulin-Independent Diabetes", because they have no problem producing insulin, but instead are unable to respond to the insulin that is produced. As a result their insulin receptors undergo a down regulation and are exocytosed.
What is the function of the Ligamentum Arteriosum?
The Ligamentum Arteriosum is one of the many remnants that we will find in the thoracic/abdominal region that were useful during embryonic development, but are non-functional. In the case of the Ligamentum Arteriosum, it is a fibrous ligament connecting the Arch of the Aorta to the Left Pulmonary Artery. In the developing embryo, it was previously called the Ductus Arteriosus, and it allowed blood to shunt directly from the right ventricle of the heart to the Ascending Aorta, and not going through the pulmonary arteries so that the blood could bypass the still developing, fluid filled lungs of the developing embryo.
