AHPT 604 - Test 1 Questions AndAccurate Answers
kinesis: - Answer to move
logy: - Answer to study
Kinematics: - Answer study of movement without regards to the forces creating the
motion
Kinetics: - Answer study of movement in regards to the forces creating the motion
What are the 2 types of motion? - Answer translation and rotation
Translation describes ... - Answer a linear motion in which all parts of a rigid body move
parallel to and in the same direction as every other part of the body
Rotation describes ... - Answer a motion in which an assumed rigid body moves in a
circular path around some pivot point. As a result, all points in the body simultaneously
rotate in the same angular direction (clockwise or counterclockwise) across the same
number of degrees
Translation in a curved line: - Answer curvilinear
Translation in a straight line: - Answer rectilinear
Osteokinematics describes ... - Answer the motion of bones relative to the three cardinal
planes of the body: sagittal, frontal, and horizontal
Movement in the sagittal plane: - Answer flexion and extension
dorsiflexion and plantar flexion
forward and backward bending
Movement in frontal plane: - Answer adduction and abduction
lateral flexion
ulnar and radial deviation
eversion and inversion
Movement in horizontal plane: - Answer internal and external rotation
axial rotation
Human center of mass: - Answer located generally just anterior to sacrum
, axis of rotation: - Answer the pivot point for angular motion of the body or body parts
Active movements are caused by: - Answer Stimulated muscle
Passive movements are caused by: - Answer sources other than active muscle
contraction, such as a push or pull from another person, the pull of gravity, or tension in
stretched connective tissues
Bones rotate around a joint in a plane that is _____ to an axis of rotation - Answer
perpendicular
Degrees of freedom: - Answer number of independent directions of movements allowed
at a joint
Open kinematic chain describes ... - Answer a situation in which the distal segment of a
kinematic chain, such as the foot in the lower limb, is not fixed to the earth or another
immovable object; therefore, the distal segment is free to move
Closed kinematic chain describes ... - Answer describes a situation in which the distal
segment of the kinematic chain is fixed to the earth or another immovable object; The
proximal segment is free to move
Arthrokinematics describes ... - Answer the motion that occurs between the articular
surfaces of joints
What are the three fundamental arthrokinematics that occur between curved joint
surfaces? - Answer roll, slide, spin
In _________-on-__________ arthrokinematics, the roll and the slide are in opposite
directions. - Answer convex-on-concave
In _________-on-__________ arthrokinematics, the roll and the slide are in the same
direction - Answer concave-on-convex
Define roll: - Answer multiple points along one rotating articular surface contact multiple
points on another articular surface
analogy: a tire rotating across a stretch of pavement
Define slide: - Answer a single point on one articular surface contacts multiple points on
another articular surface
analogy: a nonrotating tire skidding across a stretch of icy pavement
Define spin: - Answer a single point on one articular surface rotates on a single point on
another articular surface
analogy: a toy top rotating on one spot on the floor
close-packed position: - Answer position of maximal congruency
