What are neurotransmitters?

• Consists of the brain and spinal cord

• A nerve cell

• The 3 layers of membranes that cover and protect the brain and spinal cord

What is the role of the hypothalamus?

• Controls the autonomic nervous system; also plays a role in emotions

• Part of the autonomic nervous system that prepares the body for action ("fight or flight")

• Part of the autonomic nervous system that counteracts "fight or flight" and returns the body to normal working conditions

• Connects with the spinal cord and regulates heartbeat, respiration, swallowing, coughing, and blood pressure
