2. FUN FACTS: Muscular System
You use 14 muscles to smile and 43 to frown.
The human body has more than 650 muscles.
The strongest muscle of the body is the tongue, and every person has a unique tongue print.
The muscle that lets your eye blink is the fastest muscle in your body. It allows you to blink 5 times a second.

3. Muscular System
Function: Works with skeletal system to produce voluntary movement; helps to circulate blood and move food through the digestive system
Structures: Skeletal muscle, smooth muscle, and cardiac muscle

4. 3 KINDS OF MUSCLE TISSUE
Cardiac
Striated
Smooth

5. Skeletal System Functions: Protects organs and supports the body
Works with muscles to allow movement
Stores fat and minerals
Make red blood cells in the bone marrow
Structures: Bones, cartilage, ligaments, and tendons

6. FUN FACTS: Skeletal System
The bones in your body are not white - they range in color from beige to light brown.
The adult skeleton contains 206 bones, and more than half them are found in your hands and feet.
The smallest bone is the “stirrup”- it is found in the ear and is less than an inch long.

11. Joints are where bones connect & move
Here are examples of the different types of joints.

12. Arthritis is when the joints become inflamed.

13. LET’S CONNECT! Ligaments is the tissue that connects bones to bones.
Cartilage is at the end of the bones to protect the bones from rubbing together.
Cartilage is a tough but flexible tissue that gives our nose and ears shape.

14. Nervous System Function:
Coordinates the body’s response to changes in its internal and external environments
Structures:
Brain, spinal cord, and peripheral nerves

15. DIVISIONS CNS: Central Nervous System
Relays messages, processes information, and analyzes information
PNS: Peripheral Nervous System
The sensory division transmits impulses from sense organs to the CNS
The motor division transmits impulses from the central nervous system to the muscles or glands
Somatic Nervous System: regulates CONSCIOUS actions (Ex. Wiggling toes)
Autonomic Nervous System : regulates automatic or involuntary actions (Ex. Heart rate)

17. Neuron Axon

18. All Working Together...
Muscles and bones work together to produce movement in response to cues from nerves.
