Biomechanics Exam 1 Flashcards
qualitative analysis
nonnumeric evaluation of motion based on direct observation
quantitative analysis
numeric evaluation of the motion based on data collected during performance
kinesiology
scientific study of human movement
biomechanics
the study of the structure and function of biological systems by means of the methods of mechanics
Linear motion
movement (straight or curved) pathway where all the points on a (body or object) move the same distance in the same amount of time
angular motion
motion around (some point) so that different regions of the same (body segment or object) do not move through the same distance in a given amount of time
Kinematics
concerned with the characteristics of motion from a spatial and temporal perspective without reference to the forces causing the motion
Kinetics
area of study that examines the forces acting on a system
Statics
branch of mechanics that examines systems that are not moving or are moving at a constant speed
Dynamics
branch of mechanics used to evaluate systems that are being accelerated
relative angle
included angle between two segments
anterior
ventral
posterior
dorsal
ipsilateral
same side
contralateral
opposite side
absolute reference frame
is one in which the axes intersect at the center of the joint and movement of a segment is described with respect to that joint
relative reference frame
is one in which the movement of a segment is described relative to the adjacent segment
sagittal plane
bisects the body into right and left halves
frontal plane
bisects the body to create front and back halves
transverse (horizontal) Plane
bisects the body to create upper and lower halves
mediolateral axis
running side to side through the center of mass of the body
anteroposterior axis
frontal plane movements occur
Longitudinal axis
transverse or horizontal occur in this axis
structural anatomy is the science of the structure of the body
True
Movement is a change in place, position, or posture occurring over time
True
Kinesiology is the study of human motion
True
the appendicular skeleton include the upper and lower extremities
True
Any angular motion has an axis of rotation
True, Occurs in plane and around axis
a relative angle
joint
Absolute angle
segment
The right arm is ipsilateral to the right leg
True
Medial is
toward the center of the body
Lateral is
away from the body
The anatomical and fundamental positions are used by biomechanists
True
Lateral flexion applies only to the movement of the head or trunk
True
