A sign of respiratory distress seen in the neck is:

accessory muscle use
muscular definition
muscular atrophy
muscular twiches

The correct answer is: accessory muscle use

When a person is experiencing respiratory distress, their body may try to recruit additional muscles to assist in breathing. These muscles are known as accessory muscles and are not typically used for breathing. In this scenario, the muscles in the neck may appear more prominent due to increased use, leading to muscular definition. Muscular atrophy, or wasting away of muscles, would not be a sign of respiratory distress. Muscular twitches may occur in any muscle during a state of distress and are not specific to the neck.
