Bones are living tissue!Every movement we make is possible
because of the INTERACTION of muscles with the SKELETAL SYSTEM.
The skeletal system is made up of a strong, connective tissue called BONE.
The skeletal system does 3 things:It serves as the ANCHOR for all the body’s
MOVEMENT.It provides SUPPORT.It PROTECTS soft organs inside the body.
2 Types of Bone Tissue
COMPACT boneFunctions as the basic SUPPORTIVE tissue
of the body.The SKELETON.The outer layer of compact bone is HARD
and TOUGH.It covers the OUTSIDE of most bones.
2 Types of Bone Tissue (cont.)
SPONGY boneMade up of a CALCIUM network.Less DENSE; strong but lightweight.MARROW is found in the spongy bone.Marrow produces RED blood cells.BLOOD VESSELS transport new red blood
cells from the marrow and carry materials and nutrients to and from the bone.
Fill in the blanks on the skeleton in your notes outline & then we’ll talk about the 2 different types of skeletons…
1.Axial Skeleton
2.Appendicular Skeleton
With your partner…
Read about the Axial Skeleton and the Appendicular Skeleton on page 16 of your textbook.
Then, on the back of your notes, create a Venn diagram to compare and contrast the 2 different skeletons.
Making Connections…JOINTS connect parts of the skeletal system.
