The word "adduction" is spelled as /əˈdʌkʃən/, with the emphasis on the second syllable. The first sound, /ə/, represents the schwa sound and the letters 'a' and 'o' are pronounced the same. The second sound, /ˈdʌk/, is made up of the letters 'd', 'u', and 'c' which make a hard /k/ sound. The last sound, /ʃən/, represents the sound 'shun' which is made by adding the letters 's', 'h', 'u' and 'n'. Adduction is a term used in anatomy and refers to the movement of a body part towards the midline of the body.
Adduction is a term primarily utilized in the fields of anatomy and physiology, referring to the movement of a body part or a structure towards the midline of the body. It denotes the action of bringing or drawing a body part or limb closer to the midline, either horizontally or vertically, in relation to the body's core. This movement occurs when the muscles or tendons contract, pulling the limb or structure inward.
In anatomical terms, adduction is the opposite of abduction, which involves movement away from the midline. Adduction is typically observed in movements involving the extremities, such as arms or legs, when they are drawn towards the central axis of the body. For instance, when an individual brings their arms down from an extended position to rest alongside their torso, or when crossing one leg over the other while sitting.
Adduction is not limited to movements involving the limbs; it can also apply to other body parts or structures. For instance, bringing the fingers together or closing the eyelids would be considered adduction. The range and degree of adduction depend on the joint type and the specific muscles involved.
Overall, adduction is a fundamental concept in understanding the range and variety of movements that occur within the human body. Its opposite, abduction, allows for increased flexibility and versatility in performing various physical actions.
1. Movement of a limb toward the central axis of the body, or beyond it. 2. A position resulting from such movement.

The word "adduction" comes from the Latin term "adductio", which is derived from the verb "adducere". "Adducere" is composed of two elements: "ad", meaning "to" or "toward", and "ducere", meaning "to lead" or "to bring". Therefore, the etymology of "adduction" can be understood as "to bring or lead toward". In anatomical terms, adduction refers to the movement of a body part toward the midline of the body.
