eccentric
All of the following are movements of the wrist except:
extension
Isometric contractions are eccentric or concentric.
false
It is the isotonic contraction that involves tension developed within muscle but joint angles remain constant.

false
The medial malleolus is an anatomical landmark located on the fibula.
false
The quadriceps muscle group functions as a decelerator to knee joint flexion in weight-bearing movements by contracting concentrically to prevent too rapid of a downward movement.

Biomechanics is the study of mechanics related to the functional and anatomical analysis of biological systems.
true
Concentric muscle actions are the shortening contraction of muscles against gravity or a resistance.
true
Isometric contraction involves tension developed within the muscle but the joint angles remain constant.
