What are the differences between flexors and extensors?

Flexors:

* Muscles that decrease the angle between two body parts.

* Located on the anterior (front) side of the body.

* Examples: Biceps brachii, rectus femoris

Extensors:

* Muscles that increase the angle between two body parts.

* Located on the posterior (back) side of the body.

*Examples: Triceps brachii, hamstrings

*Flexors and extensors work in pairs or antagonistic muscle pairs- they pull in opposite directions to control joint positions*.
