Question

In turbellarians,the nervous tissue is concentrated anteriorly in clusters of neurons called
A)longitudinal masses.
B)ganglia.
C)commissures.
D)nephridiophores.
E)protonephridia.

Accepted Answer

Ganglia are clusters of neurons that concentrate the nervous tissue anteriorly in turbellarians. Longitudinal masses are bundles of nerve fibers that run along the length of the body, commissures are connections between ganglia or longitudinal masses, nephridiophores are structures that open the excretory system to the surface, and protonephridia are flame cells that participate in excretion and osmoregulation.
