Explanation:

For question 9, messages are sent through the nervous system as electrical impulses (action - potentials) along neurons. Neurons communicate at synapses using neurotransmitters. It's the central command center as it controls and coordinates all body functions, processes sensory information, and initiates responses. For question 10, the main functions of the nervous system include sensory function (detecting internal and external stimuli), integrative function (processing and interpreting sensory information), and motor function (initiating responses to stimuli like muscle contractions or glandular secretions).

Answer:

1. Messages are sent as electrical impulses along neurons and neurotransmitters at synapses. It's the central command center as it controls and coordinates all body functions, processes sensory info and initiates responses.
2. Sensory function: Detects stimuli. Integrative function: Processes sensory info. Motor function: Initiates responses.
