THYROID NOTCH Meaning and
Definition
-
The thyroid notch, also known as the laryngeal prominence or Adam's apple, is a prominent anatomical feature located in the human neck. It is specifically formed by the protrusion of the thyroid cartilage, the largest cartilage of the laryngeal skeleton.
The thyroid notch is typically more prominent in males than in females due to the physiological differences in the development of the laryngeal prominence. During puberty, hormonal changes cause the cartilage to grow larger and project outward, resulting in a more visible thyroid notch in males.
Situated at the front of the neck, just below the hyoid bone, the thyroid notch serves as a landmark for various medical procedures like tracheotomy, where the airway is surgically opened. It is also useful in identifying the position of the vocal folds during an examination of the larynx.
The thyroid notch plays a role in the production of sound. When speaking or singing, the vocal cords vibrate, and the resonance produced by the structure of the larynx, including the thyroid notch, contributes to the formation of different tones and pitches. This is why the prominence of the thyroid notch can affect the pitch of one's voice.
Overall, the thyroid notch serves as a prominent anatomical feature in the neck, carrying both functional and aesthetic significance.

Etymology of THYROID NOTCH
The word "thyroid" derives from the Greek word "thyreoeidēs", which means "shield-shaped", referring to the shape of the thyroid gland. "Notch" comes from the Old English word "noche" and Old French word "noche", both meaning "nick or incision". Therefore, the term "thyroid notch" is derived from the combination of "thyroid", relating to the thyroid gland, and "notch", referring to a small indentation or cut in the shape of the thyroid gland. The term is used to describe the V-shaped indentation at the upper border of the thyroid cartilage in the neck.
