Fichas del conjunto (34)
- 1FlacrumThe part of a lever system that pivots; joints are the fulcrum in the body's lever systems.
- 2ResistanceThe load to be moved b a lever system; usually this involves weight when the body's lever systems are involved.
- 3EffortThe force applied to move the resistance or wight;in the body,the effort is provided by muscles exerting a force.
- 4First Class LeverFound at the elbow joint,where the triceps causes extension of the lower arm.
- 5Second Class LeverFound at the ankle,where the gastrocnemius causes plantar flexion.
- 6Third Class LeverThe majority of the body's joints act as third class levers;for example ,the biceps acting at the elbow to cause flexion acts as a third class lever system.
- 7Mechanical AdvantageThe benefit to a lever system of having either a short effort arm-giving rapid movements over a large range of movement -or a short resistance arm-giving the advantages of being able to move a heavy weight.
- 8AgonistThe prime mover -muscle that causes movement.
- 9AntagonistMuscle that relaxes to allow the agonist to contract.
- 10TendonAttach muscle to bones.
- 11IsotonicMuscle action where the muscle changes length-causes movement.
- 12IsometricMuscle action where the muscle stays the same length -used in balance.
- 13ConcentricIsotonic contraction where the muscle shortens.
- 14EccentricIsotonic contraction where the muscle lengthens-used to control downward movements.
- 15SagittalForward or backward movement.
- 16FrontalSide to side movements.
- 17TransverseRotation or turning movements.
- 18Sagittal PlaneThrough the centre,dividing the body into left and right parts.
- 19Front PlaneThrough the body from the left side to the right, separating the front and back halves to create the front plane.
- 20Transverse PlaneCutting straight through the hips to divide the top of the body from the bottom.
- 21Sagittal Plane and Transverse axisPlane and axis for forwards and backwards movements-direction for extension and flexion.
- 22Frontal Plane and Sagittal AxisPlane and axis for side to side movements-direction for abduction and adduction.
- 23Transverse Plane and Longitudinal AxisPlane ans axis for rotating movement - direction for rotation and spins.
- 24DeltoidMuscle causing flexion at the shoulder.
- 25Latissimus DorsiMuscle causing extension at the shoulder.
- 26BicepsMuscle causing flexion at the elbow.
- 27TricepsMuscle causing extension at the elbow.
- 28HamstringGroup of muscle causing flexion at the knee.
- 29QuadricepsGroup of muscles causing extension at the knee.
- 30Hip FlexorsMain agonists at the hip during hip flexion.
- 31GlutealsMain agonists at the hip during hip extension.
- 32Tibialis AnteriorMuscle causing dorsiflexion at the ankle.
- 33GastrocnemiusMuscle causing plantar flexion at the ankle.
- 34Rotator CuffGroup of muscles causing rotation at the shoulder.
