Coelom - Wikipedia
The coelom is the mesodermally lined cavity between the gut and the outer body wall. During the development of the embryo, coelom formation begins in the gastrulation stage. The developing digestive tube of an embryo forms as a blind pouch called the archenteron. In protostomes, the coelom forms by a process known as schizocoely. [6]

Coelom Definition “The coelom is the fluid-filled body cavity present between the alimentary canal and the body wall.” The true coelom has a mesodermal origin. It is lined by mesoderm. The peritoneal cavity present in the abdomen and similar spaces around other organs such as lungs, heart are parts of the coelom.

2017年6月8日 · The coelom is a body cavity found in metazoans (animals that develop from an embryo with three tissue layers: ectoderm, mesoderm, and endoderm). The cells in each tissue layer become differentiated during development, becoming different tissues, organs, and a …
What is coelom? - Types & Definition - CK-12 Foundation
The coelom is a fluid-filled body cavity that is located between the digestive tract and the outer body wall in animals. It is lined by an epithelium derived from mesoderm. This cavity provides a space in which the internal organs can be suspended and can move freely.

4 天之前 · The fluid-filled (amniotic fluid) extraembryonic coelom (cavity) formed initially by epiblast and then lined by ectoderm and surrounding extraembryonic mesoderm. In humans, it forms the innermost fetal membrane, produces amniotic fluid expanding to eventually fuse with the chorionic membrane during week 8 of development.

The extensive body cavity (coelom) is modified to form several specialized regions. Two subdivisions of the coelom are the perivisceral coelom and the water-vascular system. The perivisceral coelom is a large, fluid-filled cavity in which the major organs, particularly the digestive tube and sex organs, are suspended. Other regions… Read More

2018年5月21日 · coelom A fluid-filled (see COELOMIC FLUID) body cavity that originates by the splitting of the mesoderm of triploblastic animals. It separates the muscles of the body wall from the gut, allowing them to move independently, and provides an area for the enlargement of internal organs, thus permitting the gut to be differentiated for various ...
