Synergists are muscles that facilitate the fixation action. There is an important difference between a helping synergist muscle and a true synergist muscle. A true synergist muscle is one that only neutralizes an undesired joint action, whereas a helping synergist is one that neutralizes an undesired action but also assists with the desired action.
The muscle which can 'cancel' or to some degree reverse the action of the muscle. Muscle synergies are noted in parentheses when relevant. O (Occurrences) Number of times that the named muscle row occurs in a standard human body. Here it may also be denoted when a given muscles only occurs in a male or a female body.
Muscle coactivation occurs when agonist and antagonist muscles (or synergist muscles) surrounding a joint contract simultaneously to provide joint stability, [1] [2] and is suggested to depend crucially on supraspinal processes involved in the control of movement. [3]
Sherrington, one of the founding figures in neurophysiology, observed that when the central nervous system signals an agonist muscle to contract, inhibitory signals are sent to the antagonist muscle, encouraging it to relax and reduce resistance. This mechanism, known as reciprocal inhibition, is essential for efficient movement and helps ...
Joints are stabilised by interacting muscles, so called synergist muscle. Different synergists feature partial similar functions. Therefore, a certain movement can be formed out of different combinations and participations of muscles acting on a certain joint. Even muscles not being in a direct connection towards a certain joint can fulfill a ...
Reciprocal inhibition — While agonist muscles contract, contraction of the opposing antagonist muscles is inhibited. (Such as when alternately flexing and extending one's elbow.) Muscle spindles — Sensory nerve endings in muscle detect the change in length of the muscle and its rate of change.
Broadly, a synergist is an entity that displays synergy with respect to another entity. More specifically, a synergist may be: a synergist muscle; a substance that enhances the effect of another substance, such as a drug (see Synergy § Biological sciences) something relating to the theological position of synergism
Muscles of the gluteal and posterior femoral regions with gluteus minimus muscle highlighted. It is fan-shaped, arising from the outer surface of the ilium, between the anterior and inferior gluteal lines, and behind, from the margin of the greater sciatic notch.
