Structure and Function The brachialis is an elbow flexor that originates from the distal anterior humerus and inserts onto the ulnar tuberosity. The brachialis is one of the largest elbow flexors and provides pure flexion of the forearm at the elbow.

As a shunt muscle contracts it applies force along the bones and pulls the joint surfaces together in order to stabilise the joint. The brachialis and brachioradialis are examples of shunt muscles. Spurt muscles tend to be prime movers and the bicep brachii is classified as a spurt muscle.

Muscle A, with its functional insertion further removed from the joint axis than its functional origin, is a ‘shunt’ muscle. Muscle B, with its functional origin further removed from the joint axis than its functional insertion, is a ‘spurt’ muscle.

Spurt muscle (def) The distance from its attachment to the moving bone (distal/insertion) to the joint is greater than the distance from its attachment to the stationary bone (origin/proximal) to the joint.
