Background During amphibian metamorphosis, the crucial moment lies in the
rearrangement of the heart, reflecting the changes in circulatory demands. However, little is …

Robert H. Anderson is one of the most important and accomplished cardiac anatomists of
the last decades, having made major contributions to our understanding of the anatomy of …

Cor triatriatum is a very rare cardiac malformation characterized by the presence of an
abnormal interatrial membrane separating either the left or right atrial chamber into two …

The study aims to describe the development of the heart in Podocnemis expansa during the
incubation period and immediately after hatching. A total of 108 embryonic hearts and five …

Cardiogenesis is similar in all vertebrates, but differences in the valvuloseptal
morphogenesis among non‐crocodilian reptiles, birds, and mammals are noted. The origin …

A well-developed heart is essential for embryonic survival. There are constant interactions
between cardiac tissue motion and blood flow, which determine the heart shape itself …

The formed hearts of vertebrates are widely different in anatomy and performance, yet their
embryonic hearts are surprisingly similar. Developmental and molecular biology are making …

All animals with a vertebral column have a heart with an atrium and a ventricle, and the
atrioventricular junction is guarded by a valve of leaflets of connective tissue. The …

Srdeční síně jsou nevelké dutiny, které slouží k příjmu, uskladnění a následnému
pumpování krve do srdečních komor. V průběhu evoluce dochází k změnám srdečních síní i …

Este trabalho objetivou descrever a morfologia do coração durante o desenvolvimento
embrionário de Podocnemis unifilis sob temperatura controlada. Foram coletados 100 ovos …
