What are some body conditions we want to keep in homeostasis?

• breathing and eating

• temperature, sugar levels, oxygen, water levels, blood pressure, heart rate

• thinking and speaking

Why do we have reflexes?

• for quick protection

• for memory

• for movement

What are examples of mechanical receptors?

• radiation, such as light

• pressure, movement, tension

• odors and tastes

What are chemical receptors?

• detect pressure, movement, and tension

• detect electromagnetic radiation

• chemical signals, such as odors and tastes

What is a stimulus?

• specialized cells information travels through

• where the signal goes to spinal cord and back to muscle

• an environmental message that starts/creates a reaction
