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.

Extends the wrist and digits?
extensor digitorum
Is a quadricep tendon a flexor or extensor tendon?
Dorsi flexion and eversion are its main actions. I just can't justify this your question.
What are some foot tendons?
There are a variety of foot tendons. Some of these include the tendon of tibialis anterior, tendon of extensor halluces longus, and tendons of extensor digitorum longus.
What is the primary elbow extensor?
Biceps brachii.
What is the prime extensor of the elbow joint?
The prime extensor at the elbow is the triceps bracii.
What is the primary extensor of the wrist and fingers?
The extensor digitorum communis is an extensor of the wrist and fingers. The extensor digitorum communis is the primary extensor of the lateral four fingers IP joint and assists in wrist extension.
Muscle that extends the elbow?
extensor carpi radialis
What muscle is used in elbow extensor?
None. The ulnar collateral ligament prevents abduction of the elbow joint.
Does triceps help you to lower your hand?

What joints are used in triceps extensions?
tendons
What do the muscles do when you straighten your arm?
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.
What function do th triceps serve?
The primary function ofthe biceps brachi is suppination of the forarm, only when the forearm is suppinated does the biceps brachi assist brachialis in flexion of the elbow. The Triceps brachi is the only significant extensor of the elbow joint.
Is tricepes flexor?
Triceps muscle is not a flexor. Triceps is an extensor of elbow joint. Biceps muscle is flexor.
Do the triceps flex or extend the forearm?
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.
What Action does the extensor carpi radialis longus have on the elbow?
There is no action of the carpi radialis longus on the elbow. ?æThe carpi digitalis longus enables?æwrist action, namely the abduction and extension.
