This complex organ acts as a barrier against detrimental conditions externally and functions to maintain, in part, the delicate chemical balance internally. The exoskeleton preserves the

The noncontractile region can be further described as the body of the cell containing the sarcoplasm and nucleus. From the body of the cell a process extends to the neural junction, a condition uniqu

Ectoderm forms the secondary structures produced from invaginations of the body wall. The mesodermal parts of the genitalia house the germ cells, and provide f
