Schizocoelous pattern – Coelom

There are two patterns of coelom formation in animals schizocoelous and enterocoelous. In schizocoelous pattern, two teloblasts cells (primordial mesodermal cells) are given out from close to the blastopore. These proliferate into a pair of teloblastic bands. At first the bands are solid but later each splits forming a cavity within.
