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.
