1. Main Function: – It releases – It is a slow but widespread form of communication. More free powerpoints at http://www.worldofteaching.comhttp://www.worldofteaching.com

2. Endocrine glands Release hormones into - Hormones – and affect the activities of cells in other parts of the body. Consists of:

3. Pituitary Gland- “the Master Gland” Function: - many body functions and controls functions of other glands. Disorders: Too much growth hormones (GH) in early childhood can result in a condition called -. Robert Wadlow

4. Thyroid Gland- located in your neck Function: plays a major role in – Disorders: If the Thyroid Gland produces to much Thyroxin, it can cause a condition known as -.

5. Pancreas Function: - keep the level of glucose in the blood stable. Glucagon tells the liver to convert glycogen to glucose and release it into blood. Insulin tells the liver to store glucose as glycogen. Disorders: When the Pancreas fails to produce or properly use Insulin- Pancreas 

6. Adrenal Gland Functions: - The adrenal glands release - -Also regulates kidney function.

7. Ovaries Functions: –Pair of reproductive organs found in women that - –Also secrete estrogen and progesterone-

8. Testes Functions: –Pair of reproductive glands that produces - –Also secrete -

9. Interaction of Glands The hypothalamus is located in the –. It is an important link between the endocrine and nervous systems. http://www.biocfarm.unibo.it/aunsnc/images/3D%20Obje cts/Hypothalamus.gif

11. Main Function: This communication – and responds to internal and external stimuli. Our nervous system allows us to feel pain.

12. Consists of: brain, - Sense Organs: Eyes, Skin, Ears, Nose & Tongue

13. A nerve is an organ containing a bundle of –. Neurons carry electrical messages called – Picture shows hundreds of severed neuron axons

14. Because neurons never touch- must travel through the space called synapse between two neurons. Neurotransmitters Synapse (gap) The message is transferred when RECEPTORS receive neurotrans- mitters. (pink spheres)

15. Parts of a Neuron 1.Cell body: cytoplasm 1.Dendrites- the neuron to the cell body. 1.Axon: long projection that – 2.from cell body 1 3 2

16. Sensory Neuron I M Interneuron Motor Neuron Muscle Contracts Synapse

17. Sensory Neuron carry – Fun Fact: Where can the largest cells in the world be found? The giraffe’s sensory and motor neurons! Some must bring impulses from the bottom of their legs to their spinal cord several meters away!!

18. Interneuron -processes impulses -- connect

19. Motor Motor Neurons - muscles & glands Axon End Axons branching out to muscle fibers

20. A reflex – spinal cord not the brain. Reflexes – what is going on. Reflex Arc

21. cell body muscle tissue TYPICAL MOTOR NEURON Axon dendrite synapse cell body

22. Nerves work together with muscles for movement. An impulse – The impulse travels down the axons of Sensory neurons – The brain will then send an impulse through motor neurons -.

23. brain Spinal Cord Cerebellum Cerebrum Medulla Oblongata Consists of:

24. Cerebrum of the body-learning, judgment Cerebellum actions of the muscles Medulla Oblongata (Brain Stem) breathing, and swallowing Spinal Cord the rest of the body

25. Consists of: -includes all sensory neurons, motor neurons, and sense organs
