Powerful pull of the triceps can also cause avulsion fractures.
For example, in the human arm, the triceps acts to extend the lower arm outward while the biceps acts to flex the lower arm inward.
The biceps is routed through a skin tunnel to the posterior side and woven into the triceps tendon to create more length.
Muscles act in pairs in opposition to each other (e.g. biceps and triceps).
Most latissimus dorsi exercises concurrently recruit the teres major, posterior fibres of the deltoid, long head of the triceps brachii, among numerous other stabilizing muscles.
It also uses predominantly triceps brachii and anconeous to extend the elbows.
We had well-built men with their biceps and triceps completely withered, and frequently they used to die.
These findings are of interest because they imply that there is a real difference to be made in the interpretation of triceps and subscapular skinfold thicknesses.
