Pronunciation: /səˈmatəˌplo͝o(ə)r/ /ˈsōmətə-/


A layer of tissue in a vertebrate embryo comprising the ectoderm and the outer layer of mesoderm, and giving rise to the amnion, the chorion, and part of the body wall. Often contrasted with splanchnopleure.
Example sentences
  • Outside the amniotic ectoderm is a thin layer of mesoderm, which is continuous with that of the somatopleure and is connected by the body-stalk with the mesodermal lining of the chorion.
  • Simultaneously, rapid growth causes the embryo to fold laterally, resulting in the somatopleure layers folding in laterally to enclose the gut.
  • The somatopleure, which is close to the ectoderm, is involved in the formation of the lateral and ventral walls of the embryo.


Late 19th century: from somato- 'of the body' + Greek pleura 'side'.
