The '''triceps brachii''' ([[Latin]] for "three-headed" [muscle] of the arm) is the large muscle on the back of the human [[upper limb]]. It is the muscle principally responsible for extension of the [[elbow]] joint (i.e. straightening of the arm). Though a similarly-named muscle, the [[triceps surae]], is found on the [[lower leg]], the triceps brachii is commonly called simply the "triceps". |

==Terminology== |
|||
The proper plural form of the [[adjective]] ''triceps'' is ''tricipes'', a form not in general use; instead, ''triceps'' is used in both [[singular]] and [[plural]] (i.e., when referring to both arms). The form ''{{sic|tricep}}'', though common even in professional contexts, is incorrect. The error may derive from a mistaken belief that ''triceps'' is a plural noun (rather than a singular adjective), since English typically forms its plurals with the addition of the letter ''s'' to the end of a word stem. |
|||
==Origin and insertion== |
|||
{{Unreferencedsection|date=March 2008}} |
|||
The three heads have the following names and origins: |
|||
*The "Long head": [[infraglenoid tubercle]] of the [[scapula]] |
|||
*The "Lateral head": posterior [[shaft of the humerus]], lateral and superior to the [[Radial sulcus|radial (spiral) groove]]. |
|||
*The "Medial head": posterior [[shaft of the humerus]], medial and inferior to the radial (spiral) groove. |
|||
The fibers converge to a single tendon to insert onto the [[olecranon process]] of the [[ulna]] (though some research indicates that there may be more than one tendon.)<ref>{{cite journal | author = Madsen M, Marx R, Millett P, Rodeo S, Sperling J, Warren R | title = Surgical anatomy of the triceps brachii tendon: anatomical study and clinical correlation | journal = Am J Sports Med | volume = 34 | issue = 11 | pages = 1839–43 | year = 2006 | pmid = 16735585 | doi = 10.1177/0363546506288752}}</ref> |
|||
Many mammals have a fourth head, the "Accessory head", which lies between the Lateral and Medial heads. In humans, the [[Anconeus muscle|Anconeus]] is sometimes loosely called "the fourth head of the triceps brachii". |
|||
==Actions== |
|||
The triceps is an [[extensor muscle]] of the elbow joint, and is 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. |
|||
The triceps accounts for approximately 70 percent of the upper arm's muscle mass. |
|||
==Training== |
|||
The triceps can be worked through either isolation or compound elbow extension movements, and can contract statically to keep the arm straightened against resistance. |
|||
Isolation movements include cable push-downs, "skull-crushers", and arm extensions behind the back. Examples of compound elbow extension include pressing movements like the [[push up]], [[bench press]] (flat, incline or decline), [[military press]] and [[dips]]. Using a closer grip stabilizes the arm allowing more weight to be used, so the triceps can be worked harder without assistance from the [[pectoral]]s or deltoids. |
|||
Static contraction movements include pullovers, straight-arm pulldowns, and bent-over lateral raises, which are also used to build the [[deltoid]]s and [[latissimus dorsi]]. |
|||
Elbow extension is important to many athletic activities. As the biceps is often worked more for aesthetic purposes, this is usually a mistake for fitness training. While it is important to maintain a balance between the biceps and triceps for postural & effective movement purposes, what the balance should be and how to measure it is a conflicted area. Pushing and pulling movements on the same plane are often used to measure this ratio. |
