CHAPTER 7: Human Movement Science Flashcards
Define Flexion
Bending movement that DECREASES the angle between bones of a joint.
(In relation to the ANATOMICAL POSITION in the sagital plane.)
Define Extension
Generally, the straightening of a joint.
Straightening movement that increases the angle between to adjacent segments of a joint.
(ANATOMICAL POSITION in the sagital plane.)

Ankle EVERSION (sole turned outward)
Ankle INVERSION (sole turned inward)

Arthrokinematics
(hint: think arthritis)
Surface movement of a joint. Invisible to the naked eye.
Three major types of arthrokinematics joint movements
Roll
Slide
Spin
Osteokinematics
(hint: think osteo=bones)
Movement of a LIMB that is visible.
In general, what is the Axial skeleton?
Part of skeleton that is the principal supportive structure of the body, oriented along its median longitudinal AXIS.
Parts of the skeleton that make up the AXIAL skeleton.
Skull
Vertebrae
Sternum
Ribs
(Hyoid Bone)
Appendicular Skeleton
All parts of the skeleton that are not classified in the axial skeleton.
Parts of the skeleton that make up the APPENDICULAR skeleton
All parts of the skeleton except the skull, ribs, sternum and spinal vertebrae. (and hyoid bone)

How are sesamoid bones classified?
–Mostly bone
–Developed in tendons
–Often mixed with fibrous tissue and cartilage
