In human anatomy, the biceps brachii is a muscle located on the upper arm. The term biceps brachii is a Latin phrase meaning "two heads of the arm", in reference to the fact that the muscle consists of two bundles with a common insertion point near the elbow. The biceps has several functions, the most important simply being to flex the elbow and to rotate the forearm. Image File history File links Gray411. ...

Anatomy

Proximally, the short head of the biceps attaches to the coracoid process of the scapula.

Distally, biceps attaches to the radial tuberosity, and because this bone can rotate, the biceps also supinates the forearm. The biceps also connects with the fascia of the medial side of the arm, at the bicipital aponeurosis. The radius and ulna of the left forearm, posterior surface. ... Opposite the bend of the elbow the tendon of the biceps brachii gives off, from its medial side, a broad aponeurosis, the lacertus fibrosus (aponeurosis of biceps muscle of arm, bicipital fascia) which passes obliquely downward and medialward across the brachial artery, and is continuous with the deep fascia covering...


Two additional muscles lie underneath the biceps brachii. These are the coracobrachialis muscle, which like the biceps attaches to the coracoid process of the scapula, and the brachialis muscle which connects to the ulna and the humerus. The coracobrachialis is one of the three muscles that attach to the coracoid process of the scapula. ... Brachialis is a flexor muscle in the upper arm. ... The ulna (Elbow Bone) [Figs. ... The humerus is a long bone in the arm or fore-legs (animals) that runs from the shoulder to the elbow. ...


Functions

The biceps is tri-articulate, meaning that it works across three joints. These joints and the associated actions are as follows: A joint (articulation) is the location at which two bones make contact (articulate). ...

The most important of these functions are to flex the elbow and to supinate the forearm. This article does not cite its references or sources. ... Elbow redirects here. ... This article or section does not cite its references or sources. ...


Supination

An example of an arm flexed in a supinated position with the biceps fully contracted.

One of the main functions of the biceps is to allow supination of the forearm, which refers to the allowing the forearm, and subsequently, the palm, to be rotated or moved, not dissimilar to the movement of the biceps curl. This has also been achieved through the use of functional electrical stimulation as a means of emulating electrical impulses used within the synapses, and allow slight movement within those with paralysis.

It has also been proven through several tests into muscle group stimulation, that supination of the forearm with an isometric grip allows for close and normal-grip bench press exercises to have a much more profound effect on the biceps brachii and the clavicular portion of the pectorialis major. [citation needed] Isometrics is a form of exercise involving the contraction of a muscle without the shortening of the angle of the joint. ...

Originally, supination of the forearm was attributed as a function of the brachioradialis muscle. However, the original idea of the biceps acting as a supinator was something hypothesised by Leonardo da Vinci, in a series of annotated drawings made between 1505 and 1510 (referred to as his Milanese period); in which the principle of the biceps as a supinator, as well as its role as a flexor to the elbow was devised. However, this function remained undiscovered by the medical community as Da Vinci was not regarded as a teacher of anatomy, nor were his results publicly released. Brachioradialis is a muscle located in the forearm, that acts to flex the elbow. ... Leonardo di ser Piero da Vinci (April 15, 1452 – May 2, 1519) was an Italian polymath: architect, anatomist, sculptor, engineer, inventor, mathematician, musician, and painter. ...


It was not until 1713, that this movement was re-discovered by William Cheselden, and subsequently recorded for the medical community, being rewritten several times by different authors wishing to present information to different audiences. Nevertheless, the most notable recent expansion upon Cheselden's recordings was achieved by Guillaume Duchenne in 1867 in a journal named Physiology of Motion, something which to this day is one of the major references on supination action of the biceps brachii. // Events April 11 - War of the Spanish Succession: Treaty of Utrecht June 23 - French residents of Acadia given one year to declare allegiance to Britain or leave Nova Scotia Canada first Orrery built by George Graham Ongoing events Great Northern War (1700-1721) War of the Spanish Succession (1702-1713...

The term biceps brachii is a Latin phrase meaning "two-headed [muscle] of the arm", in reference to the fact that the muscle consists of two bundles each with its own origin but with a common insertion point near the elbow.
These are the coracobrachialis muscle, which like the biceps attaches to the coracoid process of the scapula, and the brachialis muscle which connects to the ulna and the humerus.
One of the main functions of the biceps is to, along with the supinator muscle, aid in supination of the forearm, which refers to the allowing the forearm, and subsequently, the palm, to be rotated or moved toward the anatomical position, the resulting hand position not dissimilar to that of the biceps curl.
