Skeletal And Muscular System Flashcards
Tendon
Connect muscle to bone
Ligament
Connect bone to bone
Flexion
Decrease in the size of the angle at a joint e.g. bicep curl
Extension
Increase in the size of the angle at a joint e.g. throwing a ball
Adduction
Movement of a body part towards the body e.g. forehand shot in tennis
Abduction
Movement of a body part away from the body e.g. backhand shot in tennis
Hinge Joint
Examples include elbow and the knee. Flexion and extension can occur here.
Ball and socket joint
Examples include the hip and shoulder. Abduction, adduction and rotation can take place here.
Synovial Membrame
Produces synovial fluid
Synovial Fluid
Provides lubrication at a joint
Dorsiflexion
Pointing the toes up at the ankle e.g. passing a ball in football.
Plantar Flexion
Pointing the toes down at the ankle e.g. diving from a board
Rotation
Movement around an axis in a circular motion e.g. bowling in cricket
Cartilage
Prevents friction/bones rubbing together, acts as a shock absorber to allow easier movement
Concentric Contraction
When the muscle contracts and shortens e.g. when when bending the elbow the biceps is the agonist
