Horizontal Adduction- movement of arm in the transverse plane from a lateral position to an anterior position
Extension-to straighten out a joint
Frontal Plane-longitudinal plane dividing the body into front and back halves
Abduction-away from midline
Anteroposterior Axis-imaginary line around which the frontal rotations occur
Momentum-a measure of the motion of a body equal to the product of its mass and velocity
Center of Gravity-point around which the mass and weight of a body are balanced
Adduction-towards midline
Muscle Endurance-ability of the muscle to exert tension over time
Static Position-constant state of motion
Posterior Pelvic Tilt-pelvis tilted back aiding with flexion
Hip Flexors-rectus femoris, Iliopsoas, Sartorius, Pectineus, Tensor fascia latae
Knee Flexors-Semitendinous, Semimembranosus, Vastus medialis, Biceps femoris, Sartorius
Agonist-muscle acting to cause movement
Antagonist-muscle acting to slow or stop movement
Superior-structure being closer to the head or higher than another structure
Flexion-joint is bent or angle between bones of the joint or decreased
Hip Extensors-gluteus maximus, semitendinosus, semimembranosus, biceps femoris
Sagittal Plane-longitudinal plane dividing the head and torso into left and right parts
Mediolateral Axis-imaginary line around which sagittal plane rotations occur
