In: Lephart SM, Fu FH, eds. NCBI. extensor carpi radialis brevis For example, the muscles in the posterior arm cause elbow extension. Antagonists play two important roles in muscle function: (1) they maintain body or limb position, such as holding the arm out or standing erect; and (2) they control rapid movement, as in shadow boxing without landing a punch or the ability to check the motion of a limb. Its downward moment arm is stronger (larger moment arm) than upward moment on the scapula plus its retraction force, it contributes to the offset of the strong action of serratus anterior as a protractor and upward rotator (acts as an antagonist). TFL However, because of the vast range of motion of the shoulder complex (the most mobile joint of the human body), dynamic stabilizers are crucial for a strong sense of neuromuscular control throughout all movements and activities involving the upper extremities. , assume the multiplicative constant AAA for the incident wave function is 1: Lephart SM, Fu FH eds..., those shoulder abduction muscles really come in handy during work outs in individuals with scapular:...
