Final answer:
If the vocal cords are observed closed while viewing the glottis and need to be examined or manipulated, the proper action is to open the vocal cords. This is usually done either manually with an instrument or by asking the person to breathe deeply or phonate.
Step-by-step explanation:
When you have the glottis in view but the vocal cords are closed, the correct action would depend on the context of the situation. In a normal physiological state, the vocal cords can be closed when not producing sound or to prevent particles from entering the trachea. However, if the goal is to examine the vocal cords or perform a procedure that requires them to be open, then the action to take would be to open the vocal cords (Option 1).
The vocal cords can be opened manually by an instrument or they may open naturally when the person breathes deeply or makes an effort to phonate. It's important to note that the epiglottis, which covers the opening of the trachea during swallowing to prevent aspiration, is different from the vocal cords and is not what is being referred to here. Understanding the anatomy of the larynx, including the role of the epiglottis, the glottis, and the true and false vocal cords, is essential for correctly responding to the situation in question.
