Chapter 5: Human Movement Science Flashcards
The science concerned with the internal and external forces acting on the human body and the effects produced by these forces.
Biomechanics
Positioned above a point of reference
Superior
Position below a point of reference
Inferior
Positioned nearest the center of the body, or point of reference.
Proximal
Positioned farthest from the center of the body, or points of reference
Distal
On the front of the body.
Anterior (or ventral)
On the back of the body.
Posterior (or dorsal)
Positioned near the middle of the body.
Medial
Positioned toward the outside of the body
Lateral
Positioned on the opposite side of the body
Contralateral
Positioned on the same side of the body
Ipsilateral
The position with the body erect with the arms at the sides and the palm forward. The anatomic position is of importance in anatomy because it is the position of reference for anatomic nomenclature.Anatomic terms such as anterior and posterior, medial and lateral, and abduction and adduction apply to the body when it is in the anatomic position.
Anatomic position
An imaginary bisector that divides the body into left and right halves
Sagittal plane
A bending movements in which the relative angle between two adjacent segments decreases.
Flexion
A straightening movement in which the relative angle between two adjacent segments increases
extension
Extension of a jointed beyond the normal limits or range of motion
Hyperextension
Imaginary bisector that divides the body into front and back Avenues
Frontal plane
A movement in the frontal plane away from the midline of the body
Abduction
