• fluid
• chemical

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 peripheral nerves will receive signals from the brain but will be unable to send signals

What is the main function of the endocrine system?  

• it creates chemicals that are sent around the body to maintain homeostasis
