small brain and longitudinal nerve cords

• nerve net

• cephalization

• central nervous system

• peripheral nervous system

neurons that carry info into and out CNS

• nerve net

• cephalization

• central nervous system

• peripheral nervous system

contracts contraction and expansion of thee gastrovascular cavity

• nerve net

• cephalizaiton

• central nervous system

• peripheral nervous system

elongated, bilaterally symmetrical bodies have specialized systems

• true

• false

ganglia

• segmentally arranged clusters of neurons

• in annelids

• in anthropods

• segmentally arranged clusters of proteins which affect neurons

In vertebrates: brain and spinal chord relates to
