Exam 1 - Part 2 Flashcards
movement in a straight line
translational motion
movement around an axis
rotational motion
combination of rotational and translational movements
curvilinear Motion
most common motion produced by the body
Curvilinear (coupled) motion
plane that divides right and left
Sagittal plane
plane that divides anterior and posterior
frontal (coronal) plane
plane that divides superior and inferior
Transverse plane
line around which a motion occur
Axis
the three axes of motion are each formed by the _________
junction of 2 planes
how many degrees of freedom for each joint?
6 (3 translational and 3 rotational)
movement that takes place along an axis
translational
movement that takes place around an axis
rotational
which axis is at the junction of the coronal and transverse planes
X-Axis
which axis is at the junction of the coronal and sagittal planes
Y-Axis
which axis is at the junction of the sagittal and transverse planes
Z-Axis
