(1) In addition, we believe that the agonist / antagonist muscle ratios are important values when considering how the scapula provides stability, mobility, and symptom-free function.

(2) There is a failure to select the right agonist muscles

(3) Alternate between agonist and antagonist muscle groups (e.gu2026 quadriceps and hamstrings), and alternate sides.

(4) To every agonist , there is an antagonist.

(5) But now, replying to Harapha's taunts with a startling invitation to combat, Samson is confident as the agonist was never before depicted.

(6) The agonist and antagonist muscles work in concert to create muscular balance in the human body.

(7) For example, the highly potent opioid receptor agonist etorphine is not a medically useful drug because it can only be used a few times before the body becomes desensitized to the drug.

(8) They may mimic naturally occurring steroids, act as hormone receptor agonists or antagonists or alter the enzymes responsible for hormone synthesis and degradation.

(9) An agonist is described as a drug that binds to and activates receptors; the possibility of spontaneous receptor activity and therefore of inverse agonism is not mentioned.

(10) Pharmacologically, it is characterized by the constitutive activity of the ligand-free receptor, and by the inverse, partial, and full agonism due to the bound ligand.

(11) Muscles may act as agonists , antagonists, synergics and fixators.

(12) Medications that can reduce androgen levels include estrogen, gonadotropin-releasing hormone agonists , and glucocorticoids.

(13) Rather, all known abused drugs affect a limited number of neurotransmitters by agonism or antagonism of a specific receptor site.

(14) These observations provide support for the model that glucose and structurally related sugars are agonists of the Gpr1 receptor.

(15) Opioid receptor agonists act at sites that are distributed throughout this circuit to produce analgesia.

(16) Studies have clearly demonstrated that key therapies in the acute attack of migraine share the common pharmacologic activity of serotonin receptor agonism .

(17) It's a matter of muscle aesthetics: The upper arm looks best when both its opposing muscle groups, the agonists and antagonists - that's bis and tris to you - carry a complementary amount of muscle.
