The other two layers are the [[ectoderm]] and the [[endoderm]]. The mesoderm is the middle layer and gives rise to a variety of tissues and structures in the body.<br /> <br /> ==Formation==<br /> The mesoderm forms during the process of [[gastrulation]], which occurs after the formation of the [[blastula]]. During gastrulation, cells migrate to form the three germ layers. The mesoderm is formed between the ectoderm and the endoderm.<br /> <br /> ==Derivatives==<br /> The mesoderm differentiates into several key structures and tissues, including:<br /> <br /> * The [[notochord]], which is a rod-like structure that provides support in the early embryo.<br /> * The [[somites]], which are segmented blocks of mesoderm that give rise to the [[vertebrae]], [[skeletal muscle]], and [[dermis]] of the skin.<br /> * The [[intermediate mesoderm]], which forms the [[urogenital system]], including the [[kidneys]] and [[gonads]].<br /> * The [[lateral plate mesoderm]], which splits into two layers: the [[somatic mesoderm]] and the [[splanchnic mesoderm]]. The somatic mesoderm contributes to the formation of the [[limbs]], [[body wall]], and [[parietal serous membranes]]. The splanchnic mesoderm forms the [[heart]], [[blood vessels]], and [[visceral serous membranes]].<br /> <br /> ==Function==<br /> The mesoderm plays a crucial role in the development of the [[circulatory system]], [[musculoskeletal system]], and [[excretory system]]. It also contributes to the formation of the [[reproductive system]] and the [[connective tissues]] throughout the body.<br /> <br /> ==Clinical Significance==<br /> Abnormal development of the mesoderm can lead to various congenital disorders. For example, defects in the formation of the notochord can result in [[spina bifida]], a condition where the [[spinal cord]] does not develop properly.<br /> <br /> ==See Also==<br /> * [[Ectoderm]]<br /> * [[Endoderm]]<br /> * [[Gastrulation]]<br /> * [[Embryogenesis]]<br /> * [[Somite]]<br /> * [[Notochord]]<br /> <br /> ==References==<br /> {{Reflist}}<br /> <br /> ==External Links==<br /> {{Commons category|Mesoderm}}<br /> <br /> [[Category:Developmental biology]]<br /> [[Category:Embryology]]<br /> [[Category:Animal developmental biology]]<br /> [[Category:Medicine]]<br /> <br /> {{Embryology}}<br /> {{medicine-stub}}</div>
