What are the 2 types of Kinematics | Osteokinematics and Arthokinematics |
3 Planes of Motion with their Axis of Rotation | 1. Saggital Plane (Frontal Axis) 2. Coronal Plane (Saggital Axis) 3. Transverse Plane (Vertical Axis |
Distal fixed, Proximal moves (eg. Squats and Pull Ups) | Closed Kinetic Chain |
Limb segment free to move in multiple directions (eg. Leg Curl/Extention | Open Kinetic Chain |
Describe the Convex on Concave relationship | Roll + Slide opposite to limb motion |
Describe the Concave on Convex relationship | Roll + Slide + Limb motion in the same direction |
Force + distance btw force and axis of rotation | Torque |
Length between axis of rotation and perpendicular intersection of force | Moment Arm + moment arm = + force |
Load and Force Opposite, Joint in the middle | First Class Lever (Head, Neck, and Cervical Muscles |
Joint and Force Opposite, Load in middle | Second Class Lever (Bracoradialis against Gravity) |
Joint and Load are Opposite, Force in middle | Third Class Lever (Brachradialis and Dumbell) |
Direction of muscular force - determines the action of muscle | Line of Pull |
Only tissue able to regenerate 100% | Bones |
What makes up the axial skeleton? | Skull, hyoid bone, vertebrae, robs |
Function of the skeletal system? | 1. Movement 2. Support 3. Protection 4. Mineral + Fat Storage 5. Blood pdt 6. Mineral homeostasis |
What are the two bone tissue types? | Cortical Compact Bone and Cancellous Porous Bone |
What type of bone tissue absorbs compressive forces and is thickest around the shaft? | Cortical Compact Bone |
What type of bone tissue redirects force and resists local stress; little beams or trabeculae are present. | Cancellous Porous Bone |
What are the Types of Bones and an example of each? | 1. Flat: Scapula 2. Long: Femur 3. Short: Carpals 4. Irregular: Vertebrae 5. Seasmoid: Patella |
Joint Classification: Binds bones together, transmits force from one bone to another. Example? | Synarthosis: Sutures of the skull |
Joint Classification: Provides shock absorption and limits motion. Example? | Cartilaginous or Ampiarthrosis: Intervertebral Disks |
Joint Classification: Fluid filled, between 2 bones | Diarthrosis |
List examples of Diarthosis Joints | Hinge Pivot Ball and Socket Ellipsoid Condyloid Saddle Plave |
