When the brachialis acts as the agonist, the biceps brachii often serves as a synergist, especially during flexion of the elbow. While the brachialis is primarily responsible for flexing the elbow joint, the biceps brachii enhances this movement, particularly when the forearm is supinated. Other muscles, like the brachioradialis, may also assist in this action, depending on the position of the arm.
brachialis
Agonist muscles are the primary muscles responsible for producing movement. However, synergist muscles are helper muscles that assist the agonist in executing a particular movement. Synergists help stabilize the movement and control the direction in which the force is exerted.
Technically speaking it's the abs. The agonist muscle in a situp is actually the hip flexors.
In a sit-up, the primary agonist muscle is the rectus abdominis. This muscle contracts to flex the spine and bring the torso towards the thighs. Other muscles, such as the hip flexors, also assist in the movement but the rectus abdominis is the main muscle responsible for the action.
The Coracoid process of the ulna is a triangular projection with a rough surface. The Coracoid process is the insertion site for the brachialis muscle.
The agonist being the biceps brachii group. The two synergist muscles that assist the biceps brachiiare the brachialis and to a lesser extent the brachioradialis.

Synergists aid agonists by promoting the same movement.a synergist :)

the antagonsit is the tricep but im not sure what the synergist is sorry : revised : the synergist in a biceps curl would be the posterior deltoid as it flexes to stabilize the shoulder, as the secondary role of the biceps brachii in a biceps curl is to pull the elbow forward and upward in an arc towards the shoulder. if you were looking at the synergists to the biceps brachii as an agonist in its usual role, then the brachioradialis would be the synergist.
hm...if I had to take a wild guess....I would guess serratus anterior and pec minor.
The three functional roles in a movement that are used to characterize muscle groups are Origin, Insertion, & Contraction (Actions). However my instructor argued that the key word was functional therefore the answer she felt was correct is/was agonists, antagonists, or synergists.
