Chapter 5 Flashcards
Human Movement Science
the study of how internal and external forces affect a living body (ESPECIALLY the skeletal system)
biomechanics
a position ABOVE a point of reference
superior
a position BELOW a point of reference
inferior
a position near the CENTER of your body or a point of reference
proximal
What is an example of a proximal joint position?
your knee joint is more proximal to your hip joint than your ankle joint is.
a position that is FARTHER away from the center of your body or point of reference
distal
What is an example of a distal body position?
your ankle is more distal to your hips than your knees are.
refers to the front of your body facing forward
anterior / ventral
refers to the back of your body
posterior / distal
refers to things close to the midline of the body
medial
Give an example of a medial body part…
adductors
positioned on the outside of the body
lateral
Give an example of a lateral body part…
abductors
these are body parts located on the same side of your body
ipsilateral
Give an example of two ipsilateral body parts…
your left foot is ipsilateral to your left hand
Describe the anatomic position…
body is erect, arms at your side with palms facing forward.
this plane splits the body into RIGHT and LEFT halves.
sagittal
What are movements in the sagittal plane?
Extension and flexion
this is a vertical plane breaking up the body into frontal and posterior planes; right angles.
frontal
What are movements in the frontal plane?
abduction and adduction
the plane that divides the body into a lower and upper section
transverse
What are movements in the transverse plane?
internal and external rotation
bending movement where a relative angle between two adjacent sections decreases.
flexion
movement in which the relative angel between adjacent section increase.
extension
extension beyond normal limits of the body
hyperextension
the act that typically moves a limb AWAY from the midline of the body.
abduction
the act that typically moves a limb TOWARDS the midline of the body.
adduction
when a limb rotates in the transverse plane going towards the midline of the body
internal rotation
when a limb rotates in the transverse plane going away from the midline of the body
external rotation
