8. REGULATION (control) Nervous EndocrineSkeletalMuscular SYSTEMS INVOLVED

9. SKELETAL SYSTEM Main Parts: – Bones – Joints – Ligaments (join bone to bone) – Tendons (join muscle to bone) – Cartilage

10. SKELETAL SYSTEM Main Functions: – Gives support & structure – Protects internal organs – Helps you move

12. MUSCULAR SYSTEM Main Parts: – Smooth muscle involuntary movement – Cardiac (heart) muscle involuntary movement – Skeletal muscle voluntary movement

13. MUSCULAR SYSTEM Main Function: – Moves your limbs & body – Moves food through the digestive tract – Pumps the blood – Constricts and dilates blood vessels to increase or decrease blood flow

15. NERVOUS & ENDOCRINE SYSTEMS Function together to regulate the body through electrical & chemical signals

17. NERVOUS SYSTEM Main Parts: – Brain – Spinal cord – Neurons (nerve cells) – Sensory organs

18. How It Works: – “Wired” – Chemical signals transmitted between nerve cells or receptors turn into electrical impulses that travel along the neuron – Quick, almost instant responses Reflexes happen before your brain knows what’s going on – Short-term effects

19. Path of a Reflex A sensory neuron Carries the impulse To the spinal cord Where the impulse Is immediately Passed back through A motor neuron to Produce a response! Why is the brain bypassed?

20. ENDOCRINE SYSTEM Main Parts: – Glands – Hormones

21. ENDOCRINE SYSTEM How It Works: – “Wireless” – Chemical signals (hormones) sent anywhere in the body Sent through the bloodstream – Slow-acting responses – Long-term effects

22. Endocrine glands Release hormones into the bloodstream. Hormones are chemicals released in one part of the body that travel through the bloodstream and affect the activities of cells in other parts of the body. Consists of: ENDOCRINE SYSTEM

23. GlandFunction ThyroidBody’s metabolism PancreasKeep the level of glucose in the blood stable. Pituatary Secretes hormones that directly regulate many body functions and controls functions of other glands. Adrenal Releases Adrenaline in the body that helps prepare for and deal with stress. Ovaries Found in women that produce eggs. Also secrete estrogen and progesterone, which control ovulation and menstruation. TestesFound in men that produces sperm. Also secrete Testosterone to give the body its masculine characteristics.

24. The “Master Gland!” The The pituitary gland, located in the brain, is an important link between the endocrine and nervous systems. It is called the master gland because it produces hormones that control other glands.

25. Reaction Time Lab Background: The brain processes stimuli from the environment through its five senses: sight, taste, touch, sound, and smell. Think of an example of how your brain processed each of these types of stimuli as you got ready for school this morning. Problem: Is there a measurable difference between the rates at which one can process sensory information obtained visually, orally, and tactually? Materials: meter stick and stopwatch Hypothesis: Guess which stimulus you can process faster: sight, sound, or touch.

26. Part I: Visual 1. Obtain a meter stick. 2. Hold a meter stick vertically with the “0 cm” end down and approximately at waist height. (The 100 cm end would be high in the air) 3. Have your partner hold their writing hand with her thumb and forefinger held even with the bottom (0 cm end) of the meter stick with one digit on each side of it as if they were going to squeeze it. 4. Prepare to drop the meter stick. 5. Drop the meter stick and have your partner try to catch it as quickly as they can. Don’t give any verbal warnings of when you will drop it. 6. Record the distance the meter stick fell before your partner grabbed it by looking at the number of the meter stick their fingers grabbed. Enter your data on to the data table. 7. Repeat this procedure until you have recorded 3 data points. Part II: Auditory 1. Repeat the procedure above, but this time have the “catcher” close his or her eyes. The dropper indicates when the meter stick is dropped by saying “Now”. It is very important that the dropper says, “Now” exactly when the meter stick is dropped. 2. Record the distance the meter stick fell. 3. Repeat this procedure until you have recorded 3 data points. Part III: Tactile 1. Repeat the procedure above, but this time have the “catcher” close his or her eyes. The dropper indicates when the meter stick is dropped by tapping their shoulder. It is very important that the dropper taps their shoulder exactly when the meter stick is dropped. 2. Record the distance the meter stick fell. 3. Repeat this procedure until you have recorded 3 data points.

27. Conclusion – Copy question and write out answer in complete sentences: 1. Which type of stimulus did your group respond to the best? 2. Why do you think that is? 3. Which type of stimulus did your group respond to the worst? 4. Why do you think that is? 5. Which hand is your writing hand? 6. Did you catch the ruler faster with your left hand or right hand? Why might this be so? 7. Why did you run several trials for each hand? 9. How might the results change if you did this experiment with a person of 70 years old? Why might this be so? Conclusion: Was your hypothesis supported? Support your answer with your data. Were there any sources of error? What did you learn in this experiment? Must be included in your I.A.N.

28. DEBRIEF: Explain how the four systems work together to prevent injury if you touch a hot stove. The nervous & endocrine systems recognize the increased temperature, and send signals to the skeletal & muscular systems to move the body away from injury.
