Olecrenon process of the ulna
The triceps brachii is the muscle of the body primarily used to extend the elbow. It is a long muscle that originates in the scapula.
The proximal attachment of the anconeus muscle is the lateral epicondyle of the humerus, while the distal attachment is the olecranon process of the ulna. The anconeus muscle plays a role in assisting the triceps brachii muscle in extending the forearm at the elbow joint.
Triceps brachiiElbow flexion is due to the contraction of the biceps brachii, the prime mover. The triceps brachii extends as the biceps brachii contracts and therefore is the antagonist muscle.
The Triceps brachii
The Triceps Brachi is the antagonist for the Corachobrachialis, the Brachialis and the Biceps Brachi
your brain.... i think its that dont get mad if its not!
Triceps Brachii - it is the only muscle fleshing out the posterior humerus; its three heads arise from the shoulder girdle and proximal humerus, and it inserts into the olecranon process of the ulna. It is a powerful prime mover of elbow extension.triceps brachii
Triceps brachii
Long (Scapular) Head: Infra-glenoid tubercle at the lateral border of scapula inferior to the glenoid fossa
I think you are referring to the triceps. This is the muscle that attaches at the elbow and the shoulder. The one that you use when extending your arm. biceps; up triceps; under
Agonist - Pectoralis Major, Triceps Brachii Antagonist - Bicep Brachii, Latissimus Dorsi
Biceps lies anterior whereas triceps is posterior
