Today’s Standard: describe the interactions that occur among [animal] systems that perform the functions of…regulation… (B.10A)
Now set up your next page… Date: 3/9/16 Title: Regulation Essential Question: Why do we need regulatory systems?
Notes will be fast paced today… Keep questions and comments minimal and on-task
SYSTEMS INVOLVED INJURY Endocrine Skeletal Muscular Nervous We didn’t have time to get this one in yesterday….
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.
SYSTEMS INVOLVED REGULATION (control) Nervous Endocrine
NERVOUS SYSTEM Main Parts: Brain Spinal cord Neurons (nerve cells) Sensory organs Eyes Ears Tongue Nose Skin
NERVOUS SYSTEM How It Works: “Wired” Electrical signals transmitted between nearby cells Quick, instant responses Reflexes happen before your brain knows what’s going on Short-term effects
ENDOCRINE SYSTEM Main Parts: Glands Hormones
ENDOCRINE SYSTEM How It Works: “Wireless”- not directly connected Chemical signals (hormones) sent anywhere in the body Sent through the Circulatory System Slow-acting responses Long-term effects
DEBRIEF: Explain why we need the nervous and endocrine systems. The nervous and endocrine systems control all the body’s responses, so no other organ system would be able to function without these two regulatory systems.
