Two parts of the system above are labeled with "A" and "B".  Look closely at what these labels are pointing at.  Which answer best describes both parts “A” and “B” in the diagram below?  

• central nervous system only
• brain and motor nerves
• peripheral nervous system only
• central nervous system and peripheral nervous system

Which answer best describes part “A” in the diagram above?  Consider both lines in the diagram!

• peripheral nervous system
•  central nervous system
• sensory nerves
• the longest nerve cell in the body

Which statement best describes the function of the nervous system in the body?  

• to protect other organs and tissues
•  send messages to body parts using only chemicals
• to gather information through the senses (stimuli) and also control all other body systems
• to transport oxygen and carbon dioxide

 Which statement best describes the interactions between the nervous system and the bicep – which is a skeletal muscle in the arm?  

• the nervous system sends chemical messages to the bicep so that it makes new cells
• the nervous system sends electrical signals “telling” the bicep cells to contract
• the nervous system provides an attachment point for the bicep
• the nervous system supplies the oxygen to the bicep cells

The skeletal system interacts with the nervous system by protecting the spinal cord.  However, if a person breaks his neck, it is common that the spinal cord is damaged or even completely ripped.  What is the likely effect of a broken neck?  

• the person will be unable to blink and smile
• the person will be able to move arms and legs but much more slowly
• the brain will not be able to communicate with the peripheral nerves
• the peripheral nerves will receive signals from the brain but will be unable to send signals

Only one of the following statements is true.  Analyze the statements to determine which is completely true about how the endocrine system and cardiovascular system work together. 

• The endocrine system uses glands to produce hormones that travel with the blood through the blood vessels.
• The endocrine system uses glands to produce electrical signals that travel through the blood vessels.
• The endocrine system uses nerve cells to control all other systems including the cardiovascular system and the beating of the heart.
• The endocrine system uses white blood cells to kill diseases that might infect the body.

What is the main function of the endocrine system?  

• it creates chemicals that are sent around the body to maintain homeostasis
• it creates electrical messages that are sent around the body to maintain homeostasis
• it maintains the correct level of oxygen in the body to maintain homeostasis
• it releases waste from the body to maintain homeostasis
