  Transverse Plane and In the Superior & Inferior
• The sagittal plane occurs around the _____ Axis of Rotation

  Medial & Lateral

  Compression and Tension
• If asked to label a curve of load and deformation the four main points that you should know when moving along this curve are?

  1. Elastic Region
  2. Yield Point
  3. Plastic Region
  4. Breaking Point
• The 2 static stabilizers for joints are ______ and _______

  Boney Congruency and Joint Capsule
• Articular Cartilage functions minimize both ____ and _____

  Friction And Compression
• The Most Superficial Layer of Articular Cartilage is called the ____

  Lamina
• Diarthrodial Joints can be classified off of their axes of rotation, these axes of rotation are??


  Triaxial, Biaxial, Uniaxial and Non Axial
• The soft tissue with the most orderly arrangement of collagen is?

  Tendons
• The soft tissue with the least orderly arrangement of collagen is?

  Skin
• Osteokinematics means " _____ _____ _____:

  Measuring Bone Motion
• The Function of the mineral part of the bone is ___

  Hardness
• The function of the collagen portion of bone is ____

  Flexibility & Elasticity
• If the loading of a cylinder through the face is seen it may cause?

  Rotation
• When a concave surface moves across a convex surface, roll and glide are in the _____ direction

  Same Direction
• The malalignment Coxa Vara will most likely be paired with ?

  Genu Valgum
• In the cross girdle phenomena the hip extensors are ____ and the hip flexors are _____

  Tight

  Weak
• The most superficial layer of cortical bone is ____

  Periosteum
• Bone is built best for which type of force

  Compression
• Match The different Axes of rotation to their corresponding plane:

  Sagittal Plane - Medial-Lateral Axis

  Frontal Plane - Anterior-Posterior Axis

  Transverse Plane - Longitudinal Axis
• Short bones allow us to _____

  Change and reform around structures and objects
• The Two Different parts of extracellular matrix and the roles that it plays within the bones are:


  Ground Substance - Holds it together

  Water - Supports All Function
• The two main structural differences of bone are seen within what two types of bone.

  Compact and Spongy Bone
• Periosteum is the ____

  Dense Fibrous Membrane that envelops the Diaphysis
• The biomechanical properties of bone are that bone is ____ and _____

  Viscus and Elastic
• Compression causes Atoms to get closer together along the long axis
• Tension causes atoms to get further apart along the long axis
• Shear causes the atoms to get shifted in opposing directions along the long axis
• If osteoclasts outpace osteoblasts too much bone is reabsorbed causing a chance for stress fractures
• If Osteoblasts outpace these osteoclasts too much bone will be laid down
• Fibrous Joints are Bones held together by fibrous CT which have no joint capsule
• Cartilaginous Joints are joints that are held together and connected by cartilage
• Synovial Joints are seen in the space between articulating joints and have the potential for loss of space or inflammation
• A Suture is seen as a less fibrous connective tissue which results in a tighter fit
• The Three different layers of a synovial joint are the joint capsule, the synovial membrane and the Synovial Fluid
• The roles of articular cartilage is to reduce friction as well as disperse forces out
• The Sagittal Plane has the most amount of motion
• The primary functional task of the sagittal plane is related with propulsion and absorption
