* <spoiler text="What protein makes-up senile amyloid in the ventricle of the heart?">Transthyretin.</spoiler>
* <spoiler text="What protein makes-up senile amyloid in the atrium of the heart?">Atrial natriuretic peptide.</spoiler>
* <spoiler text="At what age does senile amyloidosis usually develop?">Eighth and ninth decades.</spoiler>
* <spoiler text="Where else may senile amyloid deposits occur?">Senile amyloid deposits also occur in the lungs, pancreas, and spleen. Senile cerebral amyloidosis occurs due to deposition of A beta 2 protein in cerebral blood vessels and in senile plaques of Alzheimer's disease patients.</spoiler>
