Movement of forearm upside down with static elbow, is known as :

Question

Accepted Answer

The movement of the forearm upside down with a static elbow is known as "Pronation & Supination," which is correctly identified as Option 2. Here's a detailed explanation:

1. **Pronation & Supination (Option 2):**
   - Pronation and supination are movements that occur at the forearm. Pronation refers to the rotation of the forearm so that the palm faces downward or backward, while supination is the opposite movement, rotating the forearm so that the palm faces upward or forward. These movements occur at the radioulnar joints, allowing the radius and ulna (the two bones of the forearm) to cross over each other. This is the correct description of the movement of the forearm upside down with a static elbow.

2. **Flexion & Extension (Option 1):**
   - Flexion and extension are movements that typically occur in the sagittal plane, involving the bending and straightening of a joint. In the context of the elbow, flexion refers to bending the elbow so that the forearm moves closer to the upper arm, while extension refers to straightening the elbow. These movements do not describe the rotation of the forearm, hence they are incorrect for the given question.

3. **Abduction & Hyperabduction (Option 3):**
   - Abduction refers to the movement of a limb away from the midline of the body, while hyperabduction is an exaggerated form of abduction. These terms are generally used in the context of movements at the shoulder or hip joints, not the forearm. Therefore, they do not apply to the movement described in the question.

4. **Adduction & Hyperadduction (Option 4):**
   - Adduction is the movement of a limb toward the midline of the body, and hyperadduction is an exaggerated form of adduction. Similar to abduction, these terms are used for movements at the shoulder or hip joints and do not describe the rotational movement of the forearm. Thus, they are incorrect for this context.

In summary, the correct answer is Option 2, "Pronation & Supination," as it accurately describes the rotational movement of the forearm with a static elbow. The other options do not pertain to this specific movement and are therefore incorrect.
