  Triceps Brachii
The biarticulate long head of the triceps brachii [1 ] enters passive insufficiency through the completion of elbow flexion when the shoulders are more flexed and abducted or through the completion of shoulder flexion and abduction when the elbows are more flexed.
The biarticulate long head of the triceps brachii [1 ] enters active insufficiency through the completion of elbow extension when the shoulders are more extended and adducted (other heads of the triceps becomes more active) or through the completion of shoulder extension and adduction when the elbows are more extended.
When the shoulder is internally rotated, the ability of the long head of the triceps brachii to extend and adduct the shoulder is diminished.

 Biceps brachii muscle - Encyclopedia, History, Geography and Biography
The term biceps brachii is a Latin phrase meaning "two heads of the arm", in reference to the fact that the muscle consists of two bundles with a common insertion point near the elbow.
These are the coracobrachialis muscle, which like the biceps attaches to the coracoid process of the scapula, and the brachialis muscle which connects to the ulna and the humerus.
It has also been proven through several tests into muscle group stimulation, that supination of the forearm with an isometric grip allows for close and normal-grip bench press exercises to have a much more profound effect on the biceps brachii and the clavicular portion of the pectorialis major.

 Triceps brachii muscle - Encyclopedia, History, Geography and Biography
The triceps brachii muscle is a large three-headed skeletal muscle found in humans.
The triceps account for approximately 60 percent of the arm's mass, but people who exercise the arms with weights often neglect this group of muscles in favour of the biceps brachii.
In sports such as (american) football, the triceps are a far superior muscle group than the biceps and should be exercised in much greater detail.

 Building Bigger Stronger Arms: Triceps
The triceps kickback has a reverse torque pattern, overloads the triceps at its weakest position of full extension, and recruits all three heads.
The triceps extensor or stabilization response: Pressure on the ulnar surface of the palm (little finger-side) causes a neuromuscular reflex that allows greater contraction of the triceps.
Obviously, dips are one of the better triceps exercises, provided the person is strong enough, or their shoulders are healthy enough to perform them with good form.

 Muscles of the Arm
The anconeus muscle is located chiefly in the forearm, but it is described with the brachial muscles because it is morphologically and functionally related to the triceps brachii muscle.
This is a flattened, fusiform muscle that lies posterior to the biceps brachii.
This is an elongated, narrow muscle in the superomedial part of the arm and is important mainly as a landmark (e.g., the musculocutaneous nerve pierces it).

It differs in thickness at different parts, being thin over the Biceps brachii, but thicker where it covers the Triceps brachii, and over the epicondyles of the humerus: it is strengthened by fibrous aponeuroses, derived from the Pectoralis major and Latissimus dorsi medially, and from the Deltoideus laterally.
The Biceps brachii is a flexor of the elbow and, to a less extent, of the shoulder; it is also a powerful supinator, and serves to render tense the deep fascia of the forearm by means of the lacertus fibrosus given off from its tendon.
The long head of the Triceps brachii descends between the Teres minor and Teres major, dividing the triangular space between these two muscles and the humerus into two smaller spaces, one triangular, the other quadrangular (Fig.

It is a continuation of the axillary artery and it originates from the lower margin of teres major muscle and continues down the arm, until it reaches the cubital fossa at the elbow.
These supply the muscles of the upper arm, such as biceps brachii muscle and triceps brachii muscle, and contribute to important anastomotic networks of the elbow and (as the axillary artery) the shoulder.
The pulse of the brachial artery is palpable on the anterior aspect of the elbow and, with the use of a stethoscope and sphygmomanometer (blood pressure cuff) often used to measure the blood pressure.

The term biceps brachii is a Latin phrase meaning "two heads of the arm", in reference to the fact that the muscle consists of two bundles each with its own origin but with a common insertion point near the elbow.
One of the main functions of the biceps is to, along with the supinator muscle, aid in supination of the forearm, which refers to the allowing the forearm, and subsequently, the palm, to be rotated or moved toward the anatomical position, the resulting hand position not dissimilar to that of the biceps curl.
It has also been proven through several tests into muscle group stimulation, that a supinated grip allows for close and normal-grip bench press exercises to have a much more profound effect on the biceps brachii and the clavicular portion of the pectoralis major.

 Biceps brachii muscle   (Site not responding. Last check: )
In human anatomy, the biceps brachii is a muscle on the upper arm that acts to flex the elbow.
It is arguably the best known muscle, as it lies fairly superficially, and is often well-defined even in non-athletes.
The biceps brachii is innervated by the Musculocutaneous nerve (C5-C7).

The triceps brachii is the opposing muscle to the biceps.
Conversely, the biceps lengthens as the triceps shortens to extend the elbow.
Extension is the triceps primary function although the long head of the muscle does cross the shoulder joint and contributes to shoulder extension and adduction.

The third is between the tubercles of the humerus, for the passage of the long tendon of the Biceps brachii.
The muscles in relation with the joint are, above, the Supraspinatus; below, the long head of the Triceps brachii; in front, the Subscapularis; behind, the Infraspinatus and Teres minor; within, the tendon of the long head of the Biceps brachii.
The muscles which raise the scapula are the upper fibers of the Trapezius, the Levator scapulæ, and the Rhomboidei; those which depress it are the lower fibers of the Trapezius, the Pectoralis minor, and, through the elavicle, the Subclavius.
