0 a muscle that moves an arm, leg, or other body part into a straight position from a bent one --
1 a muscle that allows you to make part of your body straight --
Large longitudinal extensor and flexor muscles derived from the longitudinal body wall muscle in the forebody extend into the hindbody.
To achieve this type of motion, only two extensors will be coordinately actuated at the same time.
The right one is then called the front auxiliary extensor and the left one the rear auxiliary extensor.
The stroke lengths of all extensors are the same.
This label sequence represents the sequence of the extensor states of a gait.
The extensors changing from 0 to 1 are shaded in the figure for illustration.
This causes triceps weakness and increased involvement of wrist extensors and finger extensors.
This could be caused by short length of flexors and extensors muscle groups and/or lack of muscular power.
