One of the challenges that scientists face when classifying a new fossil is that any tiny detail is all that separates one species from another. Further exploration is required to identify another set of characteristics that may help in deciding which organism belongs or create a new class.

Brain, spinal cord, nerves
The brain controls thought, behavior, emotion, memory, and basic life functions. The brain is also the origin of control over body movement. The spinal cord connects the peripheral nervous system (PNS) to the brain; nerve impulses reaching the spinal cord through sensory neurons are transmitted up into the brain. Nerves primarily involve control and coordination of all parts of the body.
The nervous system interacts with every other organ system. For example the hypothalamus in the brain controls the pituitary gland and tells it when to produce hormones, this shows that the nervous system interacts with the endocrine system.
Hope this helps :)
