They are muscles the pull your head back. So if you are walking along, minding your own business and hear a fighter jet cruising through the sky, when you tilt your head back so you can look up to see they are about to shoot some terrorist down, you will be using your neck extensor muscles. Conversely, when you realize that its actually just a 747 taking off, but you trip over a curb because you weren't looking were you were going, you will probably look down in preparation for impending fall. Looking down uses your neck flexors. As a rule of thumb, flexor and extensor muscles always work in opposition and generally occur in a plane that is perpendicular to the body in its anatomical position. Flexors reduce the angle of the joint (ie biceps brings forearm closer to arm) and extensors increase the angle of the joint (triceps brings forearm away from arm).

Where is your back extensors located?
Low back
Examples of flexors and extensors?

What nerves control the extensors muscles?
The Radial Nerve.
What are the main functions and importance of the hip flexors and extensors in the human body?
The main functions of the hip flexors and extensors are to help with movement and stability in the hip joint. The hip flexors are important for activities like walking, running, and bending at the waist, while the hip extensors are crucial for activities like standing up straight and lifting objects. Strong hip flexors and extensors are essential for overall mobility and strength in the body.
