These circles are not moving, your brain is making them appear to move. Try focusing

on one circle. It will stop moving.

•The control center•Protected by the skull

•Made up of approx. 1 trillion neurons•Divided into two

hemispheres

Right

Left •Each hemisphere controls the opposite part of the body.Ex. The Left hemisphere

controls that right side of the body

Look at the chart and say the color, NOT the word

Your right brain tried to say the color,

but your left brain was reading the word.

The brain consists of three major

parts:

1.Cerebrum

2.Cerebellum

3.Medulla oblongata

Page 12: Using your prior knowledge EXPLAIN in multiple sentences how the game “Simon Says” works? Homeostasis: Regulation How does the nervous system help us.

•The largest part of the brain•Located on both the right and left hemisphere

•The center for thought, memory, learning, senses and voluntary movements.

If a human system fails to function properly, what is the most likely

result?

1. a stable rate of metabolism 2. a disturbance in homeostasis 3. a change in the method of cellular

respiration 4. a change in the function of DNA

Two types of human cells are shown in the diagram below.

Cell A causes the cells at B to contract. This activity

would be most useful for1. lifting a book from a bookshelf 2. coordinating the functions of organelles 3. digesting food in the small intestine 4. carrying out the process of protein synthesis

Imagine you’ve stepped off a curb and a car doing 70 mph,

comes out of nowhere. Identify 2 human body

systems at work to help you respond to this stimuli. How do they work together to help you maintain homeostasis???

•A cluster of nerves that run along the back

•Protected by the

______________ Vertebrae (backbone)

Page 28: Using your prior knowledge EXPLAIN in multiple sentences how the game “Simon Says” works? Homeostasis: Regulation How does the nervous system help us.

A group of nerve cells (neurons) that carries the

messages known as impulses.

Page 29: Using your prior knowledge EXPLAIN in multiple sentences how the game “Simon Says” works? Homeostasis: Regulation How does the nervous system help us.

Structural unit of the brain and

nervous system which conduct

information and carry messages throughout an

organism.

Specialized structures that are sensitive to stimuli

physical or chemical changes within or outside an organism that cause a response

Ex. Eyes, ears, skin, nose

• One microscopic nerve cell• Basic unit of the

nervous system

•There are 100 billion neurons in the brain

Page 37: Using your prior knowledge EXPLAIN in multiple sentences how the game “Simon Says” works? Homeostasis: Regulation How does the nervous system help us.

3 Types of

Neurons• Found in receptors

(sense organs) • Receive stimulus • Send impulses

from receptors to the spinal

cord and brain.

1. Sensory Neurons:

Page 38: Using your prior knowledge EXPLAIN in multiple sentences how the game “Simon Says” works? Homeostasis: Regulation How does the nervous system help us.

• Found in the spinal cord & brain.

• Receive impulses from sensory neurons

• Interpret “process” stimulus

• Send response command to the motor neurons

2. 2. Inter-NeuronsInter-Neurons:

Page 39: Using your prior knowledge EXPLAIN in multiple sentences how the game “Simon Says” works? Homeostasis: Regulation How does the nervous system help us.

• Receives the impulses from the inter-neuron,

• Sends response impulse to the effectors.
