Final answer:
The cricothyroid membrane (ligament) is located between the cricoid and thyroid cartilages, as part of the larynx which is involved in voice production and respiration.
Step-by-step explanation:
The cricothyroid membrane, also known as the cricothyroid ligament, is located between the cricoid and thyroid cartilages. Specifically, it's part of the larynx, which is the cartilaginous structure that connects the pharynx to the trachea and is involved in voice production and breathing. The larynx is composed of several cartilage structures, including the thyroid cartilage, cricoid cartilage, and epiglottis. The thyroid cartilage, often known for the laryngeal prominence or 'Adam's apple,' is the largest and is found at the front of the larynx. The cricoid cartilage forms a complete ring below the thyroid cartilage. The cricothyroid ligament connects these two cartilages, playing a role in the tension of the vocal folds and thus impacting voice pitch.
