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.
None. The ulnar collateral ligament prevents abduction of the elbow joint.
extensor carpi radialis
Triceps muscle is not a flexor. Triceps is an extensor of elbow joint. Biceps muscle is flexor.
extensorThe triceps brachii is an extensor. It is the large muscle on the back of the arm and is primarily the muscle used for extension of the elbow joint or straightening of the arm. The triceps is also an antagonist of the biceps and the brachialis muscles.ExtensorsTriceps is not a flexor. It is extensor of the elbow joint.
That depends on the position of your elbow joint. Triceps is powerful extensor muscle of the elbow joint.
The prime extensor at the elbow is the triceps bracii.
Straightening your arm at the elbow is called extension. Elbow extension is caused primarily by contracting the triceps brachii muscle, although the small anconeus muscle does play a role. Wrist extension is accomplished primarily by contracting the extensor carpi radialis & the extensor carpi ulnaris; but is also assisted by contracting the extensor digitorum, the extensor indicis, the extensor digiti minimi, the extensor pollicis brevis, & the extensor pollicis longus.
The main extensor of the arm is the triceps brachii muscle. It is located on the back of the upper arm and is responsible for extending the elbow joint, which straightens the arm.
tendons
A muscle having three heads; specif., the great extensor of the forearm, arising by three heads and inserted into the olecranon at the elbow.
Biceps brachii.
The triceps brachii muscle is the primary extensor of the elbow, also known as the olecranon. To clarify, it is the elbow that can also be known as the olecranon. The olecranon is the posterior process of the ulna. The triceps brachii muscle has three heads (hence TRI-, meaning three) - the long head which originates from the infraglenoid tubercle of the scapula, and the short and lateral heads which originate from the posterior surface of the humerus. The three meet and join to the olecranon of the ulna. When this muscle contracts, it pulls the olecranon in the direction of the shoulder - thus extending the forearm at the elbow joint. The triceps brachii muscle is innervated by the radial nerve, originating from spinal levels C6 and C8, but primarily C7.
