The amnion is a thin but tough sac that surrounds a developing embryo in amniotes. It is filled with amniotic fluid, which helps to protect the embryo from physical shocks and maintains a stable temperature. The amnion plays a crucial role in the development of the fetus during pregnancy.

Synonyms

amnionic sac, embryonic membrane

Examples of usage

  • The amnion provides a protective cushioning for the fetus.
  • Amniocentesis involves sampling amniotic fluid from the amnion.
  • The rupture of the amnion can indicate the onset of labor.

Etymology

The term 'amnion' has its roots in the Ancient Greek word 'amnos,' which means 'lamb.' The connection to lambs derives from the observation of the protective membranes surrounding the embryos of various animals, often lambs, in the womb. The word passed into Latin as 'amnion,' which was used in medical texts to describe the membrane in the sac surrounding the developing fetus. Over the centuries, the understanding of the amnion has expanded, particularly with advances in embryology and fetal development studies. The amnion is a defining characteristic of amniotes, a clade comprising reptiles, birds, and mammals, which is distinguished by the presence of this protective membrane during embryonic development.
