1. Nervous System

2. EQ: How do the functions of the human body systems interact?
Today I will discuss the nervous system because it is the body’s central control center, responsible for gathering and interpreting information.

3. Who Am I?
Create 5 “Yes” or “No” questions to ask the teacher about this picture.

4. The Nervous System: The Nervous System has 2 functions:
Gathers and interprets information
Responds to that information as needed

5. The Nervous System has 2 parts:
Central Nervous System (CNS): consist of your brain and spinal cord.
Peripheral Nervous System (PNS): consists of all the other parts except the brain and spinal cord.

6. The Central Nervous System:
The Central Nervous System (CNS) includes the brain and the spinal cord.
The CNS takes in and responds to information from the peripheral nervous system.

7. The Central Nervous System:
The Brain is the control center of the nervous system. It controls voluntary and involuntary processes.
The Spinal Cord sends messages to and from the brain.

8. Peripheral Nervous System:
The PNS connects all parts of your body to the CNS.
It uses specialized structures called nerves to carry the information between your body and your CNS.

9. The Peripheral Nervous System is divided into 2 parts:
Somatic Nervous System: are under your control (talking, walking, writing)
Autonomic Nervous System: Controls things in the body you do not think about (heat beating and breathing)

10. Neuron:
Messages travel through the nervous system along neurons.

11. Types of Neurons:
Sensory Neurons: gather information about what is happening in and around your body. They receive and send those messages to the CNS.
Motor Neurons: Causes the reaction for the information (Deliverers information)

12. Nerves:
A collection of axons bundled together with blood vessels and connective tissue.

13. Injuries
An injury to the brain can cause temporary or permanent damage. (ex: concussion caused by contact injury)
A spinal cord injury may block the messages to and from the brain. (ex: paralysis)

14. Exit Ticket: Gimmie Five:
Students will write down five things they learned about the nervous system
