Explanation:

The endocrine system and nervous system interact, but the endocrine system does not solely regulate the nervous system. The nervous system emits both electrical (action - potentials) and chemical signals (neurotransmitters). The endocrine system communicates through the bloodstream, not the nervous system. Neurons in the nervous system send neurotransmitters across synapses to communicate internally.

Answer:

D. The nervous system sends neurotransmitters to communicate internally.
