Learning about how our bones are anatomically structured.

• Some of the bones in our lower limb are the Tibia and Femur

  • These are really strong bones and are classified as long bones because they are longer in length than in width.

  • We have different kinds of bones in our body (206)

• Bones are not the only thing in our bodies we also have ligaments which attach bone to bone to help create stability. Some of the ones in our knees are the ACL, PCL, LCL, MCL these help provide stability. They are not stretchy but allow for certain movement

• Your knee is called a joint, there are many types of joints. The knee is a synovial joint because it contains synovial fluid to have friction free movement.

• Cartilage is also in the knee it is called a meniscus which serves as a shock absorber

Walking, running and jumping creates stress on our knees. Sometimes can create bad stress if you are overusing, improperly use our knees that can cause a lot of bad impact on our knees and other structures

Sometimes things happen and we get hurt and we injury our knees and they lose stability. This can be really painful sometimes we need to go the doctor or sometimes we just need rest.
