Abduction and addiction are two opposite functions, involving movement away from the centre line of the body, and towards the centre line of the body, respectively. When two muscles perform these two opposite functions, and are dependent on each other, they are called an antagonistic pair. This also applies to muscles that flex and extend.
A pair of large neck muscles called sternocleidomastoids is responsible for turning the head.
The biceps and triceps are muscles. They flex and extend the forearm, respectively, so they are considered antagonists.
Skeletal muscles work in pair because of the limitation that these muscles can only contract or pull and can only move in one direction.
ussually, one muscle in the pair bends part of the body.the other muscle straightens part of the body.
I think what your after is called an antagonistic pair of muscles, for example the bicep and the tricep. When the bicep is contracting the tricep relaxes and when the tricep is contracting the bicep relaxes.
i do not no
It is important because both muscle's are a pair, So they should both be exercised in a pair for the equal amount of strength in both muscles.
1 pair:m.sternohyoideus 2 pair: m.thyreohyoideus 3 pair : m.omohyoideus 4 pair. m.sternothyreoideus
These muscles are the pectoralis major and the pectoralis minor muscles.
which two pairs of muscles are antagonistic pairs?

you find muscle pairs in your legs... like you hamstrings or quadriceps.
