1.1a- Skeletal & Muscular- Movement Flashcards
Flexion
reducing the angle at a joint- bending the knee
Extension
increases the angle of a joint- straightening the elbow
Adduction
Moving the limb toward the midline of the body- bringing a leg in
Abduction
Movement away from the midline of the body- moving the arm away from the other
Rotation
the turning of a bone around its own long axis either clockwise or anti-clockwise- turning leg to point toes
Dorsi-flexion
Decrease in the angle of the joint between the foot and lower leg
plantar flexion
pointing toes, increases the angle of the ankle joint
Horizontal flexion & extension
movement of the limbs away from or to midline of body while parallel to ground
Horizontal flexion
Movement of the limbs towards the midline of the body parallel to the ground.
horizontal extension
Movement of the limbs away from the midline of the body parallel to the ground.
Isotonic Muscle Contractions
Tension is produced and there is a change in muscle length
isometric contraction
Tension produced but no change in muscle length
What two types can isotonic be broken down to?
Concentric and Eccentric
concentric
muscle shortens
eccentric
muscle lengthens
Antagonistic Pairs
Pair of muscles that work together to produce movement at a joint
Agonist
muscle that contracts to produce a movement- controls the movement
Frontal plane
divides the body into anterior and posterior portions (front and back)
Transverse plane
divides the body into superior and inferior parts (upper and lower)
sagittal plane
vertical division of the body into right and left portions
movement in sagittal plane
flexion and extension
movement in transverse plane
rotation
movement in frontal plane
abduction and adduction
