In medical dictionary upper limb is defined as “one of the paired appendages of the body used in grasping. The limb of the body extending from the deltoid region to the hand; it is specialized for functions requiring great mobility, such as grasping and manipulating, called arm”.

The upper limb is essential for our daily functioning. It enables us to grip, write, lift and throw among many other movements. The upper limb has been shaped by evolution, into a highly mobile part of the human body. This contrasts with the lower limb, which has developed for stability.

Describing in descending order it is divided into:

  • Shoulder;
  • Arm;
  • Elbow;
  • Forearm;
  • Wrist;
  • Hand;
  • Finger.

The upper limbs perform a secondary role as stabilizer meanwhile subjects are walking or running; helping the trunk remaining stable counteracting the possible compensations.

For all those reasons is very important to take care of this anatomical region. Check regularly the stability and the physiological range of motion. The absence of symptoms does not exclude joint problems that may arise in the future.
