1. QuiZZZZZZZZZZZZ!
Quiz on Neuron

2. Do Now
What is the difference between the nervous system and the endocrine system?

3. Unit 3A : Neural Processing & Endocrine System
Nervous System & Endocrine System

4. Nervous System Speedy electrochemical communication network
Fast communication
All nerves in the CNS & PNS
Nerves are a bunch of axons grouped together
2 major division of the nervous system
Central Nervous System (CNS)
Peripheral Nervous System (PNS)
Information travels through the nervous system
Via motor, sensory, and interneurons

5. Central Nervous System
Brain and spinal cord
Talks to muscles, glands, etc. via the PNS
Reflexes happen here

6. A Simple Reflex

7. A Simple Reflex

8. A Simple Reflex

9. Demo The role of thinking in reaction time Big circle
Link hands and squeeze
Stand face to back, squeeze opposite shoulder

10. Peripheral Nervous System (PNS)
Made up on sensory and motor neurons
Connects the CNS to the rest of the body
2 main divisions
Autonomics Nervous System
Somatic Nervous System

11. PNS – 2 Divisions Things your body does naturally Also has 2 divisions
Autonomic
Somatic
Things your body does naturally
Ex: heart rate, breathing, pupil dilation, digestion,
Also has 2 divisions
Sympathetic nervous system
Parasympathetic nervous system
Voluntary movement of muscles
Ex: kicking a ball, hitting a girl, playing a sport

12. PNS  Autonomic  2 Divisions
Sympathetic
Parasympathetic
Happens automatically you don’t control this
Arousing
Ex: increased heart rate, pupil dilation, relaxes bladder(tricky one)
Happens automatically you don’t control this
Calming
Ex: heart rate slowing down, stimulates digestion, contract pupils

13. The Nervous System
Q4 What are the functions of the nervous system’s main divisions?

14. The Nervous System

15. The Nervous System

16. The Nervous System

17. The Nervous System

18. The Nervous System

19. The Nervous System

20. Endocrine System Slower chemical communication system Adrenal Gland
Hormones
Ex: endorphins, testosterone
Blood chemistry
Adrenal Gland
Secrete epinephrine and norepinephrine
AKA: Adrenaline and noradrenaline
Prepares body for fight or flight response
Pituitary Gland
Most powerful gland in the Endocrine System
Controlled by hypothalamus in brain
Regulates growth and controls other glands
