| 41. | The serous cavities are formed from the intraembryonic coelom and are basically an empty space within the body surrounded by serous membrane.
|
| 42. | A metanephridium typically consists of a ciliated funnel opening into the body cavity or coelom connected to a cells lining the metanephridium.
|
| 43. | The intraembryonic coelom can now be seen as a cavity within the body which is covered with serous membrane derived from the splanchnopleure.
|
| 44. | The body cavity consists of a haemocoel, but the only place where a true coelom can be found is around the gonad.
|
| 45. | During development, echinoderm coelom is divided in metacoel, mesocoel and protocoel ( also called somatocoel, hydrocoel and axocoel, respectively ).
|
| 46. | Initially, between 1879 1883, they worked together and performed embryological studies, especially on the theory of the coelom ( 1881 ).

| 47. | :: : From the German page : The proboscis lies dorsal of the colon in a coelom ( in this case rhynchocoel ).
|
| 48. | Egg brooding is quite common and usually takes place in special chambers on their oral surfaces, but sometimes the ovary or coelom is used.
|
| 49. | The coelom or pseudocoel ( depending on the animal ) develop from the mesothelium and ( in the case of coelom ) become the peritoneum.
