Triceps Brachii Muscle - Human Anatomy - Actions

Actions

The triceps is an extensor muscle of the elbow joint and an antagonist of the biceps and brachialis muscles. It can also fixate the elbow joint when the forearm and hand are used for fine movements, e.g., when writing. It has been suggested that the long head fascicle is employed when sustained force generation is demanded, or when there is a need for a synergistic control of the shoulder and elbow or both. The lateral head is used for movements requiring occasional high-intensity force, while the medial fascicle enables more precise, low-force movements.

With its origin on the scapula, the long head also acts on the shoulder joint and is also involved in retroversion and adduction of the arm.

Famous quotes containing the word actions:

    Because impudence is a vice, it does not follow that modesty is a virtue; it is built upon shame, a passion in our nature, and may be either good or bad according to the actions performed from that motive.
    Bernard Mandeville (1670–1733)

    When a man’s life is destroyed or damaged by some wound or privation of soul or body, which is due to other men’s actions or negligence, it is not only his sensibility that suffers but also his aspiration toward the good. Therefore there has been sacrilege towards that which is sacred in him.
    Simone Weil (1909–1943)

    Our pride and self-importance are European, while our development and actions are Asiatic.
    Anton Pavlovich Chekhov (1860–1904)
