Chapter 1 Flashcards
Kinetics
Forces that cause motion
Kinematics
Branch of mechanics dealing with body in motion
Osteokinematics
Movement of two bones occuring at joint
Arthrokinematics
Motion that occurs at joint surface as result of moving bones
Sagittal Plane/ Frontal Axis
Flexion, Extension
Frontal Plane/Sagittal Plane
Abduction/Adduction
Inversion/Eversion
Radial/Ulnar Deviation
Horizontal Plane/Vertical Axis
Horizontal Abduction/Adduction
Pronation/Supination
IR/EE
R/L Rotation
Curvelinear
Movement occuring in curved path that isn’t always circular.
Linear
Occurs in straight line with movement from one point to another.
Angular
Motion occuring at fixed point.
Isometric Contraction
Muscle producing a pulling force while maintaining a constant length
Concentric Contraction
Muscle produces a pulling force as it contracts(Shortens).
Muscle attachments move towards each other.
Eccentric Contraction
Muscle produces a pulling contraction as it is being elongated.
Muscle attachments separate
Agonist
Muscle most directly related to movement
Antagonist
Muscle/group that has opposite action of agonist
