Question

Which classification term describes the placenta as disc-shaped at maturity?

Options

• Allantochorial

• Chorioallantoic

• Haemochorial

The metadiscoidal classification refers to the disc-shaped or discoidal appearance of the placenta at maturity. This flattened, disc-like morphology is characteristic of the human placenta and provides an efficient structure for the extensive surface area required for maternal-foetal exchange and hormone secretion.
