Question

Recurrent laryngeal nerve RLN - Motor

Option 1: Unilateral motor loss
Option 2: Bilateral motor loss
Option 3: Increased motor function
Option 4: No effect on motor function

Answer 1

The RLN is a motor nerve that controls the muscles in the larynx. Damage to the RLN can lead to unilateral or bilateral motor loss.

Step-by-step explanation:

The recurrent laryngeal nerve (RLN) is a motor nerve that supplies the muscles in the larynx. Damage to the RLN can lead to various motor impairments. Option 1: Unilateral motor loss refers to the loss of motor function on one side of the larynx. Option 2: Bilateral motor loss refers to the loss of motor function on both sides of the larynx. Option 3: Increased motor function does not accurately describe the effect of RLN damage. Option 4: No effect on motor function is incorrect as damage to the RLN can cause motor deficits.
