The theory is considered  constructivist  , meaning that , unlike nativist theories ( which describe cognitive development as the unfolding of innate knowledge and abilities ) or empiricist theories ( which describe cognitive development as the gradual acquisition of knowledge through experience ) , it asserts that we construct our cognitive ...
Introduction. The population frequency of a bicuspid aortic valve is â0.9% to 1.36%, 1â3 with a 2:1 male:female ratio. It is likely that the presence of a bicuspid aortic valve has a genetic basis, with the pattern of transmission in some families suggesting an autosomal dominant pattern of inheritance.
I did. So, I thought you might want to know what I learned before I went into my aortic valve replacement surgery.First, you have to know that all heart valves do not look the same. As you can see in the diagram of the heart below, heart valves differ in size.The aortic valve and the pulmonary valve are smaller than the mitral valve and the tricuspid valve.And, you can also see that the mitral valve is the only valve that is naturally bicuspid. A bicuspid valve only has two leaflets while all the other valves have three leaflets. did. So, I thought you might want to know what I learned before I went into my aortic valve replacement surgery.
