Scenes

Skeleton

  • skull - Its bones are connected by sutures. The only exception is the mandible, which is connected to the skull by a synovial joint.
  • sternum - It is formed by the fusion of three bones. Ribs are connected to it by cartilages.
  • ribs - True and false ribs are connected to the sternum by costal cartilages and to the vertebrae by synovial joints. The first seven pairs of ribs are called true ribs, as they are connected to the sternum directly, by cartilages. The next 3 pairs of ribs are called false ribs: these are connected to the cartilage of the lower true ribs. The last 2 sets of ribs, the floating ribs are not connected to the sternum.
  • spinal column - It consists of vertebrae, connected by cartilaginous joints forming intervertebral discs.
  • sacrum - It is formed by the fusion of 5 sacral vertebrae.
  • coccyx - It is formed by the fusion of 3–5 coccygeal vertebrae.
  • hip bone (coxal bone) - It is formed by the fusion of three paired bones.
  • bones of the upper limb - These bones are typically joined together by synovial joints, which allow relatively free movement of the bones.
  • bones of the lower limb - These bones are typically joined together by synovial joints, which allow relatively free movement of the bones.

Fusion

Suture

  • parietal bone
  • temporalis bone
  • frontalis bone
  • occipital bone
  • bones of the facial skeleton - The mandible is joined to the other bones by synovial joints, the other bones are joined together by sutures.

Cartilaginous joint

Synovial joint

  • convex articular surface
  • concave articular surface
  • joint capsule - A connective tissue capsule surrounding the synovial joint. It contains synovial fluid.
  • synovial joint cavity - It is filled with synovial fluid, which lubricates and reduces friction in the joint.
  • cartilage - Very durable, it covers joint surfaces and it is protected against friction by synovial fluid.
  • patella
  • fibular collateral ligament
  • tibial collateral ligament - It is prone to injury among athletes. As opposed to the anterior cruciate ligament, it often recovers easily, without requiring surgery. Ligaments connect bones with other bones, they are made up of connective tissue.
  • anterior cruciate ligament - It is the knee ligament most often injured among athletes. Its injury usually requires surgery followed by a long recovery period. Ligaments connect bones with other bones, they are made up of connective tissue.
  • posterior cruciate ligament
  • patellar ligament
