An example of an antagonist muscle is?
Antagonist muscles are muscles that counteract the action of agonist muscles.Some examples of antagonist muscles are:Triceps work opposite of biceps.Hamstrings works opposite of quadriceps.The sternocleidomastoid works opposite of the deltoids.
What muscle creates the movement when somebody touches and holds their finger on their nose?
If I'm not mistaken I believe that for this movement to happen there are two muscles that need to be used- because muscles work in pairs. For this particular movement I am sure that the Agonist muscle (prime mover), the muscle that relaxes, is the Bicep. And the Antagonist, the muscle that contracts, is the Tricep.
What is it called when two muscles work together?
When two muscles work together, it is referred to as "synergism." In this process, the muscles collaborate to produce a specific movement or stabilize a joint, enhancing the efficiency and effectiveness of the action. Synergistic muscles often assist the primary muscle responsible for the movement, known as the agonist, while the antagonist muscles relax to allow for smooth motion.
What would happen if both muscles of an antagonist pair contracted simultaneously?
This is not possible. The spinal cord is wired so that when an extensor muscle contracts, a flexor muscle must relax. It is not possible to contract antagonizing muscle groups at the same time.
What are the 2 functional characteristics used to classify muscles into classes?
The two functional characteristics used to classify muscles into classes are agonist and antagonist. Agonist muscles are responsible for causing movement, while antagonist muscles work in opposition to the agonist to help control the movement.
The iris of the eye has two main types of muscles. Name these two muscles and how they affect the pupil.?
The iris of the eye has two main types of muscles - the radial muscle and the sphincter muscle. The radial muscle lies on the outside of the iris, and the sphincter muscle surrounds the pupil, allowing it to dilate and contract.
Which types of muscles are involuntary?

What muscle tissue is the tissue of the heart?
