iii)  Bladder is generally filled with clear watery fluid having mostly plasma of the host.

iv)  Bladder wall consists of an outer cuticle and  inner mesenchyme.  [Further development of cysticercus larva takes place only when it is eaten by a  human  host, otherwise it  lodges in the tissue of the host and gets calcified. After  entering the stomach of the human host the proscolex gets evaginated, suckers and rostellum come out and anchor to the mucous membrane and the larva develops further into the adult by  proliferation.]
