Latin: M.. brachialis
- back to the arm muscles overview
- to the musculature overview
The arm flexor (musculus brachialis) is 3 cm thick and 5 cm wide, directly below the two-headed arm muscle.
Insertion / origin / innervation
Approach: Ellen roughness (Ulna tuberosity)
Origin: Attachment point of the deltoid muscle (Deltoid tuberosity)
Innervation: Musculocutaneous nerve
How is the muscle trained / contracted?
As with the biceps, a flexion of the arm is caused by a flexion in the Elbow joint reached. A classic form of exercise for isolated stress on the arm flexor muscles is Biceps curl.
Other forms of stress occur with tensile movements in the Back training on.
You can find an overview of all relevant topics in the area of strength training in the overview Weight training
The arm flexor (musculus brachialis) is a double-feathered, powerful flexor of the elbow joint.Due to the relatively short lever arm, the muscle is able to reach a deflection of 20 cm on the hand even if the hand is shortened by only 1 cm.
