Please open your notebooks and write down “The Nervous System” as the title of your notes!

Please write down everything in red!

 What is the nervous system?  The body system responsible for helping your body respond to stimuli and act accordingly  What is a stimulus?  Something that causes a response in an organism or part of the body

 What is the nervous system?  The body system responsible for helping your body respond to stimuli and act accordingly  What is a stimulus?  Something that causes a response in an organism or part of the body

Give an example of a stimulus.

What ORGANS do you think would be involved in gathering information from stimuli?

What ORGANS do you think would be involved in responding to stimuli?

 Brain: the organ of the body in the head that controls functions, movements, sensations, and thoughts  Spinal Cord: the large group of nerves which runs through the center of the spine and carries messages between the brain and the rest of the body  Nerves/Nervous Tissue: one of the many thin parts that control movement and feeling by carrying messages between the brain and other parts of the body

 Central Nervous System: Brain, Spinal Cord  Peripheral Nervous System: Nerves (sends messages to and from Spinal Cord and Brain

Autonomic Nervous System: regulates the functions of our internal organs such as the heart, stomach and intestines (Involuntary ) Question Four: Name some examples of functions regulated by the AUTONOMIC nervous system.

Somatic Nervous System: Sends sensory information throughout the body and sends messages to your muscles for movement (VOLUNTARY)

1. Name three activities controlled by the autonomic nervous system. 2. What are the three parts of the nervous system? 3. Would you like to have a life where you did not experience any physical pain? Why or why not?

 How does this disease impact this person physically? Emotionally? Mentally?  How does this disease impact this person’s family?  If you had this disease, how would it impact you and your life?  How does this nervous system disease prevent the body from maintaining homeostasis?

 Take a look at this nerve cell….  It looks very different  From “normal” cells  Why do you think these cells are long and skinny?  What is the main job of the nerve cells?  How would this long thin shape help it do its job?

Connections

 How does the nervous system connect to:  The digestive system?  The muscular system?  The endocrine system?  The respiratory system?  The circulatory system?
