What is an example of an antagonist drug?
An antagonist is a drug that blocks opioids by attaching to the opioid receptors without activating them.
Antagonists cause no opioid effect and block full agonist opioids.
Examples are naltrexone and naloxone..
Why do muscles exist in pairs?
Skeletal muscles only pull in one direction. For this reason they always come in pairs. When one muscle in a pair contracts, to bend a joint for example, its counterpart then contracts and pulls in the opposite direction to straighten the joint out again.
Is antagonist good or bad?
The antagonist can be one character or a group of characters, but they have to get in the protagonist’s way of pursuing their goals. In conventional narratives, the antagonist is synonymous with the “bad guy,” while the protagonist represents the “good guy.”
What are examples of antagonistic muscles?
Antagonist and agonist muscles often occur in pairs, called antagonistic pairs. As one muscle contracts, the other relaxes. An example of an antagonistic pair is the biceps and triceps; to contract, the triceps relaxes while the biceps contracts to lift the arm.
What is the role of the antagonist muscle?
In an antagonistic muscle pair as one muscle contracts the other muscle relaxes or lengthens. The muscle that is contracting is called the agonist and the muscle that is relaxing or lengthening is called the antagonist.
What muscles are extensors?
The opposing muscle of a flexor is called the “extensor” muscle. Your triceps is an extensor. When you contract your triceps your arm straightens and the angle between the forearm and the upper arm increases.
What is Coactivation of antagonistic muscles?
Muscle coactivation occurs when agonist and antagonist (or synergist) muscles surrounding a joint contract simultaneously to provide joint stability. It is also known as muscle cocontraction, since two muscle groups are contracting at the same time.
How do antagonistic muscles work?
Muscles transfer force to bones through tendons. They move our bones and associated body parts by pulling on them – this process is called muscle contraction. In an antagonistic muscle pair as one muscle contracts the other muscle relaxes or lengthens. …
What is muscle synergy?
Definition. … Here a muscle synergy is defined as the coordinated recruitment of a group of muscles with specific activation balances or specific activation waveforms. Recent experiments have indicated that many motor behaviors are controlled through the flexible combination of a small number of muscle synergies.

What are antagonistic drugs?
An antagonist is a type of ligand or drug that avoids or dampens a biological reaction. Upon binding to the receptor, it does not activate. Rather it tends to block the particular receptor. Sometimes, they are also referred to as blockers such as alpha-blockers or beta-blockers.
What’s the meaning of antagonistic?
: showing dislike or opposition : marked by or resulting from antagonism an antagonistic relationship factions antagonistic to one another. Other Words from antagonistic Synonyms & Antonyms More Example Sentences Learn More about antagonistic.
Which one is the meaning of antagonistic function?
Chemical antagonists impede the normal function of a system. They function to invert the effects of other molecules. … The word is most commonly used in this context in biochemistry and toxicology: interference in the physiological action of a chemical substance by another having a similar structure.
What is the difference between an agonist and antagonist?
An agonist binds to the receptor and produces an effect within the cell. An antagonist may bind to the same receptor, but does not produce a response, instead it blocks that receptor to a natural agonist. … Insurmountable antagonists bind strongly to the receptor and are not reversed by additional agonist.
What is the function of a synergist and antagonist?
Antagonist: muscles that oppose, or reverse, a particular movement. Synergist: helps prime movers by adding a little extra force to the same movement or by reducing undesirable or unnecessary movements.
