No bones about it!Slide2
5 Functions of the Skeletal System…
Provides shape and supports for bodyAllows for movement
Protects internal organsStores materials (calcium and lipids)Blood cell production (bone marrow)Slide3
The skeletal system is made up of:Bone and the joints that connect them togetherBone: Type of connective tissue that is hard and calcified
Joint: a place where two or more bones come together (can be moveable or immoveable)Slide4
Major Types of JointsSlide5Slide6
Major Types of MoveableJoints:Slide7
Immoveable/Fixed Joints…
Example: skull, pelvisSlide8
How many bones are there in the adult human?206But… humans are born with >270 bones and some fuse together as an infant to become 206 bones.Slide9

The Human Skeleton
-Major BonesSlide11
Two Main Types of Bone:Compact Bone – Solid, dense. Contains blood vessels and nerves. Strong, stores calcium. Spongy Bone
– Numerous spaces and cavities, lightweight. *both can contain bone marrow.Red Bone Marrow – produces blood cells (red blood cells, white blood cells, and platelets). Yellow Bone Marrow – stores fats (lipids)Slide12
Long BoneSlide13
Other materials associated with skeletal system:Cartilage: Soft connective tissue. Some develops into bone after birth. Some remains (nose, ears). Bones have cartilage at the ends where they meet a moveable joint
Ligaments: connective tissue that connects bone to boneTendons: connective tissue that connects muscle to bone (allows for movement)Slide14

Fun Skeletal System Facts:You were born without a patellaHumans and giraffes have the same number of bones in their neckThe longest bone in your body is your femur
The smallest bone in your body is the stapes, also called the stirrup (hardly larger than a grain of rice)The largest bone is the pelvis, which is made of 6 bones firmly joined togetherThe only bone not connected to another is the hyoid, at the base of the tongueThere are 26 bones in the footThe skeleton had a lot more cartilage when born, to be softer and allow for an easier birth. Then the cartilage hardens and forms bone.
You are born will all red bone marrow (produces blood cells), but with age, about half of it turns to yellow bone marrow (stores fats)
