​The Skeletal System Day II

Skeletal System Review

Skeletal System

Skull

Did you know the skull is actually made up of 22 bones? It helps protect the brain.

Multiple Choice

What is this a picture of?

• a robot

• a body

• a skeleton

• an invertebrate

Spine

Made up of disk-shaped bones called vertebrates. Protects the spinal cord, which is a part of your nervous system. Also supports your posture to keep you upright!

Multiple Choice

The skeleton is made up of the same things as the Skeletal System.... What is the Skeletal System made up of?

• muscles

• bones

• skin

• everything in the body

Ribs

Protects vital internal organs, such as the heart and lungs.

Function 1 - PROVIDES SUPPORT

• One job of the skeletal system is to provide support for the human body.

• The frames of the house HOLD the house UP

• In the same way, the bones of the body HOLD the body UP.

Clavicle

Also known as the collarbone, the clavicle bone is the only bone that connects the ribs to the arms and shoulders.

Multiple Choice

Which option gives the best analogy of the skeletal system providing support?

• The engine of a car helping it move.

• A shield protecting you from getting hurt.

• The Coca Cola Factory producing coke products/drinks.

• The poles and ropes help hold the tent up.

Arms

• Humerus

• Ulna and Radius

Function 2 - HELPS WITH MOVEMENT

• Another function of the skeletal system is to help with movement.

• Our BONES allow us to MOVE!

• A joint is where two bones meet as you can see in the picture.

Hands

• Phalanges - Bones that make up the fingers

• Metacarpals - Inside the palm of the hand

Femur

The femur is the longest, heaviest, and strongest bone in the human body. It connects the hip to the knee.

Multiple Choice

Which option below gives the best analogy of the skeletal system helping with movement?

• The engine of a car helping it move.

• A shield protecting you from getting hurt.

• The Coca Cola Factory producing coke products/drinks.

• The poles and ropes holding up a tent.

Tibia and Fibula

Connects the knee to the foot. Helps keep the body upright!

Function 3 - PROVIDES PROTECTION

• Another function of the skeletal system is that it provides protection for the organs

• In the picture, you can see how the rib cage (bones across the chest) is protecting the heart and other organs in that area.

Feet

Phalanges - the bones in the toes. Same name as the finger bones!

Metatarsal Bones

Tarsals

Multiple Choice

Which option best gives an analogy of the skeletal system providing protection?

• The engine of a car helping the car move.

• A shield protecting you from getting hurt.

• The Coca Cola Factory producing coke products/drinks.

• The poles or ropes help hold the tent up.

Babies have more bones!

The adult human body has 206 bones, but infants have over 300 bones! Bones naturally fuse together as the baby grows.

Function 4 - PRODUCES BLOOD CELLS

• Our skeletal system also produces blood cells for the body.

• The body produces red blood cells and white blood cells that are very important for human bodies to function properly.

• These blood cells are made in the center of your bones called the marrow.

What else do bones do?

• What would happen if we didn't have bones? https://youtu.be/_hyqlKVm2ks

• Some bones also produce red blood cells for the body.

• Bones are "strung together" by ligaments, kind of like a puppet!

Multiple Choice

Which option best gives an analogy of the skeletal system being able to produce blood cells?

• The engine of a car helps the car move.

• A shield protects you from getting hurt.

• The Coca Cola Factory produces coke products/drinks

• The poles or ropes in a tent hold the tent up.

3 Parts of the Bone

• Compact Bone - outer part of the bone, very dense and tough to protect the bone from breaking

• Spongy Bone - inside of the bone, very strong but lightweight (making the bones less heavy)

• Marrow - produces blood cells
