The base of the triangle is directed upward, and is represented by a line connecting the two epicondyles of the humerus; the sides are formed by the medial edge of the Brachioradialis and the lateral margin of the Pronator teres; the floor is formed by the Brachialis and Supinator.
It passes medialward upon the Brachialis, and piercing the medial intermuscular septum, winds around the back of the humerus between the Triceps brachii and the bone, forming, by its junction with the profunda brachii, an arch above the olecranon fossa.
As the vessel lies on the Brachialis, it gives off branches which ascend to join the superior ulnar collateral: others descend in front of the medial epicondyle, to anastomose with the anterior ulnar recurrent.

It is formed by the four lower cervical nerves and part of the first dorsal, and lies between the root of the neck and the axilla or armpit, where it breaks up into several branches.
The brachialis is a slender, flat muscle that lies under the biceps along the front of the lower half of the humerus and in front of the elbow joint.
The brachialis is innervated by the musculocutaneous nerve and the radial nerve.

 Brachialis muscle - Wikipedia, the free encyclopedia
Brachialis is a flexor muscle in the upper arm.
It lies deep to biceps brachii, and is a more powerful flexor of the elbow.
Brachialis arises from the anterior surface of the humerus, particularly the distal half of this bone.

 Bodybuilding.com - Glen Danbury - Elbow Flexion 101.
The second elbow flexor is the smaller brachialis which lies across the outer edge of the elbow and provides a visible contour between the muscles of the anterior and posterior upper arm.
The brachialis originates from the anterior distal surface of the humerus and inserts into the tuberosity of the ulna.
Secondly the fibre type compositions of the muscles could be different, with the brachialis being a shunt muscle and its role as a stabilisation muscle require more fatigue resistance and therefore a greater proportion of slow twitch fibres.

Brachialis: During elbow flexion the brachialis muscle is used in combination with other elbow flexors, regardless of whether the wrist is pronated or supinated.
The brachialis originates on the lower half and front portion of the humerus, crossing the elbow joint and inserting on the coronoid process of the ulna.
Because of this, anatomists credit the brachialis with being the "only pure flexor of the elbow," since its only action is true flexion of the elbow.

 Build Huge Biceps - The Bodybuilding Truth
For an unlucky bunch, the main contributor is the brachialis muscle, which runs underneath the outer part of the bicep.
Since everyone's point of insertion is different, for some, the brachialis may absorb the majority of stress, thus, the biceps function becomes limited.
Going with the "opposite" concept, the best way to circumvent any assistance from the brachialis would be to not lean forward, as is the case with the preacher bench, but to lie backward.

Wrong, the answer is B. Since the brachialis inserts on the ulna, contraction of this muscle causes flexion of the elbow joint.
No, the answer is A. In addition to being a supinator of the radio-ulnar joint, contraction of the biceps does what brachialis and coracobrachialis do together, flex and adduct the shoulder joint and flex the elbow joint.

 7 Tips For Massive Arms - Training Biceps and Triceps (part 2)
The brachialis muscle is a widely neglected muscle in the bodybuilding world.
The brachialis muscle is better known among kinesiologists as the workhorse of elbow flexion.
Your arsenal of brachialis exercises in the arms race include: reverse Scott curls (wide or narrow grip, low pulley or EZ bar), hammer curls, Gaspari bar curls, Zottmann curls (seated or one arm at a time on the Scott bench).

 Men's Fitness: Bigger-looking biceps - Ask Our Experts - weight training tips
Hammer curls don't target the biceps directly, but rather the brachialis, the muscle that lies between the triceps and biceps.
The best exercises for targeting the brachialis are reverse-grip curls (with either an EZ-curl bar or a barbell, whichever is more comfortable) and hammer curls.
To train your brachialis as part of your biceps training, add four sets of either hammer curls or reverse-grip curls to the end of your biceps workout.

 Building the peak - IronMagazine.com BodyBuilding Forums
The brachialis only comes into play to a large extent if you curl with a hammer or reverse grip, and/or curl with your elbows up by you ears and bring the weight behind your head (this can only be done with cables).
Now, as to the brachialis...if you are actually dumb enough to think that doing a hammer curl or a reverse curl works the bicep and brachialis in the same manner as a barbell curl then you are more pathetic than your bench press.
Doing movements with cambered bar hits the brachialis more than if you were to do the same movement with a straight bar.

 CHARM VIDEO
The analysis shows that the main contributors are the brachialis, the brachioradialis and the biceps for forearm flexion, while the main abductors are the deltoideus, the supraspinatus and the subscapularis.
This code allows the analysis of large deformation of solids, and the implementation of user-defined constitutive relationships, which is appropriate for soft tissue simulation.
Passive deformation of the brachialis muscle under stretching has thus been simulated using the complex constitutive model previously described.

Hence when the elbow is flexed the brachialis must work harder to move the load.
The brachialis lies underneath the biceps and when developed adds thickness to the arm and helps push the biceps brachii up higher - creating the illusion of a peak.
the brachialis is the muscle typically associated wit hhaving "lower biceps", and the brachioradialis is teh muscle on the posterior forearm (hairy part) which bulges up when you turn your hand away from your body and flex your biceps.

The plane of cleavage and the retracted muscle fibers were consistent with a partial rupture of the brachialis muscle, suggesting a traumatic injury rather than a malignant lesion.
Isolated rupture of the brachialis muscle appears to be a rare injury that has not been well documented.
The current case involved a partial distal brachialis tear that responded to nonoperative treatment.

Use narrow pronated grip where the spacing between both hands is roughly 4 to 6 inches.
This grip increases the amount of overload on the brachialis and brachio-radialis muscles because in this anatomical position, the biceps brachii have a rather ineffective line of pull.
At the bottom of the range of motion, the hanging position, if you are experiencing shoulder discomfort it is a warning sign that you may have less than optimal shoulder mechanics.

 Let's Talk About ... Biceps vs. Brachialis Strain
To perform a successful treatment, the practitioner needs to determine which structure is injured and where on the muscle tendon unit the injury has occurred.
When the biceps is injured, both resisted supination of the forearm and resisted elbow flexion are painful.
Both the brachialis and the biceps flex the elbow, but only the biceps supinates the forearm (so brachialis strain does not cause pain on resisted supination).

The biceps have two heads: the long head and the short head, both of them originating from the scapula and attached to the radius (a small bone in the forearm).
For the brachialis you can do almost any type of a hammer curl whether it is a cable rope, machine, or on an incline bench.
The reason is that the Brachialis is responsible for arm flexion and when your hand is not supinated, then the Brachialis will come more into play.

No true internervous plane and both the lateral part of brachialis and brachio-radialis are innervated by the radial nerve, the innervation is however proximal and de-nervation of the lateral part of brachialis is of no significance
The radial nerve must be identified in the interval between brachialis and brachio-radialis prior to deep dissection
Proximal extension between brachialis and the lateral head of triceps is possible but care should be taken in the region of the spiral groove

 The Bodybuilding Truth by Nelson Montana
For an unlucky bunch, the main contributor is the brachialis muscle, which runs underneath the outer part of the biceps.
Naturally, as the resistance is increased, the muscle fibers of the biceps come into play, which is why heavy curling will increase biceps size.
It would then stand to reason that positioning the wrist in as opposite a direction as possible would take the stress off of the brachialis and place it more onto the biceps.

The pop 'em out muscles that I'm referring to are the brachialis, pec minor and soleus, and if trained correctly, they'll pop out your arms, your chest, and your calves.
The brachialis is a large muscle beneath the biceps brachii originating on the anterior shaft (lower half) of the humerus and inserting onto the coronoid process of the ulna.
The biceps brachii was found to be preferentially recruited during the fast protocol while the brachialis was found to be preferentially recruited during the slow protocol.

A: My blueprint is to use hammer curls to develop thick and bulging brachialis (the knotty muscles on the outside of the arm) and to prod the forearms to swell out at the sides, like Popeye's, as much as they do on the top and bottom.
Barbell curls, indispensable though they are for building the most mass possible in the biceps brachii, do not hit your brachialis as effectively.
Alternate cable hammer curls Cables can be substituted for dumbbells to maximize brachialis isolation and for consistent range-of-motion resistance.
