for biceps it is triceps
Quadricepts
antagonist goes against the muscle biceps brachii are antagonistic to the triceps brachi quadriceps are antagonistic to the hamstrings an agonist works with the muscle lifting a glass of water brachialis works with the biceps
Every muscle (no matter which muscle, even a single muscle fibre-unit) have several motor neurons.
biceps - front of arms (muscle) triceps - back of arms (muscle) qaudriceps - muscle of thigh
The triceps brachii is the antagonist to the biceps brachii.
No biceps, triceps, quadriceps and muscles that you can selectivly use are voluntary muscles.
A antagonist muscle is a muscle that opposes the action of another muscle. The Triceps Brachii is the antagonist of the Biceps Brachii.
The triceps and biceps are antagonistic muscle groups; the triceps straighten the arm and the biceps pull it in the opposite way. Therefore, when the triceps contract, the biceps lengthen.
The hamstring muscle group (biceps femoris, semitendonosis, semimembranosis) are the antagonists to the quadricep group.
It tells you the number of origins. "When biceps, triceps, or quadriceps forms part of a muscle's name, you can assume that the muscle has two, three, or four origins, respectively. For example, the biceps brachii muscle of the arm has two origins, or heads."- Human Anatomy & Physiology. Eighth Edition. Elaine N. Marieb page 321

Antagonist muscles are muscles that counteract the action of agonist muscles.Some examples of antagonist muscles are:Triceps work opposite of biceps.Hamstrings works opposite of quadriceps.The sternocleidomastoid works opposite of the deltoids.
