Questions and Correct Answers, 100%
Correct. 2024/2025.
kinesis:
to move
logy:
to study
Kinematics:
study of movement without regards to the forces creating the motion
Kinetics:
study of movement in regards to the forces creating the motion
What are the 2 types of motion?
translation and rotation
Translation describes ...
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 ...
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:
curvilinear
Translation in a straight line:
rectilinear
Osteokinematics describes ...
the motion of bones relative to the three cardinal planes of the body: sagittal, frontal, and horizontal
Movement in the sagittal plane:
flexion and extension
dorsiflexion and plantar flexion
forward and backward bending
Movement in frontal plane:
, adduction and abduction
lateral flexion
ulnar and radial deviation
eversion and inversion
Movement in horizontal plane:
internal and external rotation
axial rotation
Human center of mass:
located generally just anterior to sacrum
axis of rotation:
the pivot point for angular motion of the body or body parts
Active movements are caused by:
Stimulated muscle
Passive movements are caused by:
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
perpendicular
Degrees of freedom:
number of independent directions of movements allowed at a joint
Open kinematic chain describes ...
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 ...
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 ...
the motion that occurs between the articular surfaces of joints
What are the three fundamental arthrokinematics that occur between curved joint surfaces?
roll, slide, spin
In _________-on-__________ arthrokinematics, the roll and the slide are in opposite directions.
convex-on-concave
In _________-on-__________ arthrokinematics, the roll and the slide are in the same direction
