What is the role of antagonist synergistic stabilizer and neutralizer muscle in human body?
Stabilizer - the muscle may contract to hold a body part immobile while another body part is moving. The sustained stabilizing contraction is frequently isometric. In most normal activities, proximal joints are stabilized by muscle contractions during movement of more distal joints - proximal stabilization. For an isolated movement at one joint to occur, the muscles that control the joints proximal to that joint must stabilize the proximal joints so that no motion occurs there. The antagonists for each motion at the proximal joint co-contract or contract against each other to prevent motion. Example: the quadriceps may stabilize the knee in an extended position of permit plantar flexion of the ankle as when the individual rises to tip-toe in erect position To perform isolated elbow flexion the proximal shoulder joint must be stabilized by flexors/extensors, abductors/adductors and internal/external rotators. Neutralizer - prevents unwanted motions a muscle can perform so a specific motion can occur. Mostly dependant on the angle of pull. Examples: the biceps can flex the elbow and supinate the forearm. If only elbow flexion is wanted, the supination component must be ruled out. Therefore, the pronator teres, which pronates the forearm, would contract to counteract the supination component of the biceps, and only elbow flexion would occur. Neutralizers act to cancel out an unwanted movement With wrist ulnar deviation the flexor carpi ulnaris will cause lexion and lunar deviation of the wrist. The extensor carpi ulnaris will cause extension and ulnar deviation. If ulnar deviation is desired, these muscles would contract doing two things: they would neutralize each other's flexion/extension component, and they would act as agonists in wrist ulnar deviation Stabilizers and Neutralizers both use co-contraction to prevent motion and have an antagonistic relationship. Stabilizersare associated with joints; Neutralizers are associated with muscle.
What is the role of fixator muscle in human body?
i dont know thats why i asked
What is the role of papillary muscle?
The papillary muscles are muscles located in the ventricles of the heart. The role of the papillary muscle is to prevent inversion or prolapse or the atrioventricular valves.
What is the role of calcium ions in muscle contraction?
They bind to regulatory sites on troponin to remove contraction inhibition
Microfilaments are well known for their role in what?
Microfilaments are well known for several things. They are known for amoeboid movement, formation of cleavage furrows, and the contracting of muscle cells.
Which two muscles are forearm flexors with no role in supination?
Brachialis and brachioradialis
Forearm flexore no role in supination two muscles?
brachialis
What synergist for supination of the hand?
A supinator is a synergist for supinating the hand. Brachialis is the forearm flexor which has no role in supination.
Muscle flex the spine?
Generally, the main trunk flexors are Rectus Abdominus and the Obliques (Internal and External). Quadratus Lumborum, Trapezius and Latissimus Dorsi also play a small role in flexion.
Which muscle plays a main role in breathing?
The muscle that plays the main role is the diaphragm.:)
Which of the following muscles has no direct role in flexing the forearm at the elbow?
Biceps. Brachhil
What is every muscle used in an arm wrestling competition?
There are several muscles used to actually rotate your arm about the shoulder joint. Here is a list of some of them: pectoralis major, subscapularis, coracobrachialis, biceps brachii, supraspinatus, deltoid, latissimus dorsi, teres major and minor, infraspinatus, long head of triceps. This is not a complete list of the muscles involved, but what it should say is that this is not a straight forward and simple mechanical motion. The only good (time efficient) exercise is to mimic the arm wrestling motion--with a cable machine perhaps. The role of the wrist is also a contributing factor in arm wrestling, but that is much more simple. In this part, the forearm flexors is the muscle that's used.
Witch muscle plays a main role in breathing?
The diaphragm muscle plays a main role in breathing. This muscle pushed the lungs up and down to take in or push out air.
What is the role of the skeletal muscle?
for posture and motion

Does calcium has any role in vasoconstriction?
Yes it does, as a matter of fact calcium plays a huge role in muscle contraction, as so in the smooth vascular muscle.
What is the muscle's role in the body?
to contract to cause movement.
