Movement of the joints away from the mid-line of the body is called?

Appeared in: AIIMS Patna NO - 2020

Explanation

Abduction is the specific anatomical term for the lateral movement of a body part away from the midline of the body.
A common example is raising the arm or leg out to the side, away from the center of the body.
The term is derived from Latin, where 'ab' means 'away' and 'ducere' means 'to lead' or 'to draw'.
This movement occurs at synovial joints like the shoulder and hip.

Option A: Addiction is a neuropsychological disorder characterized by a persistent and intense urge to engage in certain behaviors, often despite substantial harm and other negative consequences. It is not a term used to describe joint movement.
Option B: Adhesion refers to the abnormal sticking together of tissues or organs by fibrous bands. It is a pathological condition, often a complication of surgery or inflammation, and not a type of normal anatomical movement.
Option C: Adduction is the opposite of abduction. It describes the movement of a limb or other body part toward the midline of the body.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Anatomical Terms of Movement as background academic context rather than a clinical decision trigger.
Nurses must accurately document a patient's range of motion (ROM) using precise terms like abduction and adduction. This is vital for tracking progress after orthopedic surgery, a stroke, or in degenerative joint diseases.
Clear communication with physical and occupational therapists relies on the correct use of these terms to develop and implement effective rehabilitation plans.
What if? If a patient who had a total hip replacement is instructed to avoid adduction past the midline, the nurse must be able to identify this movement to educate the patient and prevent dislocation of the new hip joint.

How to Approach the Question

First, identify the key action described in the question stem: 'movement... away from the mid-line'.
Second, analyze the prefix of the options. 'Ab-' often means 'away from' (like in 'abnormal'), while 'Ad-' often means 'toward' (like in 'adhere').
Third, apply this prefix knowledge. 'Abduction' logically corresponds to movement 'away from' the body.
Fourth, differentiate the movement terms (Abduction, Adduction) from the non-movement terms (Addiction, Adhesion) to eliminate incorrect choices.
Finally, confirm the definition. Abduction is moving away from the midline, and Adduction is moving toward it.
