The muscles in our shoulders

Our shoulders are an important part of our ability to keep our upper bodies upright, and they also allow the arms to move in a number of different directions and to carry heavy items. They are also one area of the body that can be affected by prolonged periods of sitting. We tend to find that our shoulders start to arch, and this can cause problems in the shoulder regions as well as the neck and even cause a number of different types of headaches. It is important that when sitting at a desk for a long period of time, you use the correct chair type and that you take regular breaks.

There are eight muscles in our shoulder region that attach themselves to the bone structures of the scapula, humerus and clavicle. The muscles are what give the shoulder its shape and definition and provide it with its strength and movement range.

The muscles are:

  • Deltoids
  • Rotator Cuffs – supraspinatus, infraspinatus, teres minor and subscapularis
  • Trapezius
  • Serratus Anterior
  • Pectoralis Major
  • Pectoralis Minor

Each of these muscles allows for the shoulder to move in a certain direction, and this works by some of the muscles flexing and the others contracting. It is one of the many reasons that it is important to stretch and work out all the muscles of the shoulder with a variety of exercises and ensure that they are all equally as strong as one another.
