## Additional Accounting Flashcards

Term
 biomechanics
Definition
 a study that uses principles of physics to quantitaively study how forces interact within a living body.
Term
 superior
Definition
 positioned above a point of reference.
Term
 inferior
Definition
 positioned below a point of reference
Term
 proximal
Definition
 positioned nearest the center of the body, or point of reference.
Term
 distal
Definition
 positioned farthest from the center of the body.
Term
 anterior
Definition
 on the front of the body
Term
 posterior
Definition
 on the back of body
Term
 medial
Definition
 positioned near the middle of the body
Term
 lateral
Definition
 toward the outside of the body
Term
 contralateral
Definition
 positioned on the opposite side of the body
Term
 ipsilateral
Definition
 positioned on the same side of the body
Term
 sagittal plane
Definition
 an imaginary bisector that divides the body into left and right halves
Term
 flexion
Definition
 the bending of a joint, causing the angle to the joint to decrease
Term
 extension
Definition
 the straightening of a joint, causing the angle of the joint to increase.
Term
 frontal plane
Definition
 an imaginary bisector that divides the body into front and back halves
Term
 abduction
Definition
 movement of a body part away from the middle of the body
Term
Definition
 movement of a body part toward the middle of the body
Term
 transverse plane
Definition
 an imaginary bisector that divides the body into top and bottom halves
Term
 internal rotation
Definition
 rotation of a joint toward the middle of the body
Term
 external rotation
Definition
 rotation of a joint away from tve middle of the body
Term
 eccentric contraction
Definition
 the lengthening of a muscle
Term
 isometric contraction
Definition
 a muscle maintaining a certain length
Term
 concentric contraction
Definition
 the shortening of a muscle
Term
 force
Definition
 an influence applied by one object to another, which results in an acceleration of deceleration of the second object
Term
 length-tension relationship
Definition
 the length at which a muscle can produce the greatest force
Term
 force-couple
Definition
 muscle groups moving together to produce movement around a joint
Term
 rotary motion
Definition
 movement of the bones around the joints
Term
 torque
Definition
 a force that produces rotation
Term
 motor behavior
Definition
 the process of the body responding to internal and external stimuli
Term
 motor control
Definition
 the study of posture and movements and the involved structures and mechanisms that the central nervous system uses to assimilate and intergrate sensor information with previous experiences
Term
 synergies
Definition
 group of muscles that are recruited by the central nervous system to provide movement
Term
 proprioception
Definition
 the cumulative sensory input to the central nervous system from all mechanoreceptors that sense position and limb movements
Term
 sensorimotor integration
Definition
 the cooperation of the nervous and muscular system in gathering information, interpreting, and executing movement
Term
 motor learning
Definition
 repeated practice of motor control processes, which lead to a chance in the ability to produce complex movements
Term
 feedback
Definition
 the use of sensory information and sensorimotor integration to help the kinetic chain in motor learning
Term
 internal feedback
Definition
 the process whereby sensory information is used by the body to reactively monitor movement and the enviroment
Term
 external feedback
Definition
 information provided by some external source, such as a health and fitness professional, videotape, morror, or heart rate monitor to supplement the internal enviroment.
