What two actions make muscle movement possible?
brain says move triceps triceps contract and moves
What movement does the arm make when the triceps muscle contract?
The biceps muscle relaxes!!!!!=)
How do muscles bring about movement in an organism?
Contraction of the biceps and the relaxation of the triceps bend the arm .In straightening the arm the triceps contract and the biceps relax
What contracts when the biceps relax?
The triceps contract when the biceps relax.And, vice versa. The triceps relax when the biceps contract.
When the triceps contract what do the biceps do?
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.
Does the triceps contract concentrically during the down phase of a push up?
No, the triceps do not contract concentrically during the down phase of a push-up. Instead, they are involved in an eccentric contraction as the elbows flex and the body lowers toward the ground. This eccentric action helps control the descent and stabilize the movement. During the upward phase, the triceps contract concentrically to extend the elbows.
How are triceps and biceps useful?
When your biceps contract (and your triceps relax), your arm bends at the elbow. When your triceps contract (and your biceps relax), your arm straightens. The biceps and triceps enable you to bend or extend your arm at the elbow.
What two muscles are antagonists to themselves with flexion and extension?
The two muscles that act as antagonists to themselves during flexion and extension are the biceps brachii and triceps brachii. When the biceps contract to flex the elbow, the triceps relax, and when the triceps contract to extend the elbow, the biceps relax. This interplay allows for smooth movement and control of the arm.
What movement occurs when the hamstrings contract eccentrically?
Knee Extension
What is an example of an antagonistic pair?
A muscle that opposes the actions of another. =] A muscle that opposes the actions of another. =]
Is the coactivation of the triceps necessary for proper functioning of the biceps and vice versa?
Yes, the coactivation of the triceps and biceps is necessary for stability and proper functioning of the elbow joint during movements. The triceps stabilize the elbow when the biceps contract, and vice versa, to ensure smooth and coordinated movement.
What Muscle extends in any movement?
None. Muscles only contracts. In order to extend, the muscle on the opposite movement has to contract. For example, the biceps help flex the elbow, but it does not extend the elbow; the triceps does that.
