Exempel på brachii

• Anatomy. —The triceps brachii is the principal structure which fills the space between the posterior border of the scapula and the humerus. 

• However, radial paralysis is encountered following injury to the nerve occasioned by its being stretched, as in cases where the triceps brachii is unduly extended in restraining subjects by means of a casting harness. 

• The radial nerve supplies branches to the three heads of the triceps brachii, to the common and lateral extensors of the digit and also to the skin covering the forearm. 

• The triceps brachii is the chief antagonist of the biceps brachii. 

• Thus it is seen, the biceps brachii is a weight bearing structure, as well as one that has to do with swinging the leg. 

• It also uses predominantly triceps brachii and anconeous to extend the elbows.

• Most latissimus dorsi exercises concurrently recruit the teres major, posterior fibres of the deltoid, long head of the triceps brachii, among numerous other stabilizing muscles.

• It primarily works the anterior deltoid, with assistance from the serratus anterior, biceps brachii and clavicular portions of the pectoralis major.

• The fusion of myoblasts is specific to skeletal muscle (e.g., "biceps brachii") and not cardiac muscle or smooth muscle.

• A cell from the biceps brachii muscle may contain 100,000 sarcomeres.

• This is assisted by elbow flexors (brachialis, brachioradialis, biceps brachii) which bring the humerus to the forearm.

• The brachial artery gives off an important branch, the profunda brachii (deep artery of the arm).

• The triceps brachii and anconeus extend the elbow, and attach to the posterior side of the humerus.

• It also supplies coracobrachialis, biceps brachii, brachialis, and the forearm skin close to the insertion of each of those muscles.

• The barbell curl specifically targets the biceps brachii which is located on the front part of the arm between the shoulder and the elbow.

• It lies deeper than the biceps brachii, and is a synergist that assists the biceps brachii in flexing at the elbow.

• The nerve may pass under the coracobrachialis or through the biceps brachii. 4.

• When pronated, the brachioradialis is more active during elbow flexion since the biceps brachii is in a mechanical disadvantage.

• The bicipital aponeurosis originates from the distal insertion of the biceps brachii.

• It pierces the coracobrachialis muscle and gives off branches to the muscle, as well as to brachialis and biceps brachii.
