Segments, planes, axes Flashcards
movements based on systems of planes and axes
how many planes are there?
3
Describe the transverse plane
Divides body horizontally into superior and inferior halves
Describe the frontal plane
Divides the body into front (anterior) and back (posterior) halves.
What movements are on the frontal plane
Abduction and adduction of upper and lower limb, lateral flexion of trunk/spine
Describe the sagittal plane
divides body into right or left equal halves,
Define parisagittal plane
Any plane parallel to the sagittal plane
What movements are on the sagittal plane
Flexion and extension
What movements are on the transverse plane?
Medial and lateral rotation of shoulder, lateral rotation of the trunk
Musculoskeletal motion involves what?
Some form of rotation around an axis
What is the longitudinal axis
Vertical axis (Y) rotation within the transverse plane
What is the anteroposterior axis
(Z axis) motion within the frontal plane
