The human larynx rests in a frame of cartilage bound by ligaments and muscles. At the front is the thyroid cartilage, creating the lump at the front of the neck, known as the laryngeal prominence or more commonly as the Adam's apple.
Regarding the etymology of the term "Adam's apple", Webster's 1913 dictionary states that the term "… is so called from a notion that it was caused by the forbidden fruit, (an apple) sticking in the throat of our first parent."
Laryngeal prominence
The Adam's apple is typically more prominent in adult men than in women or prepubescent girls or boys. The growth of the adam's apple and the larynx during puberty is responsible for the voice cracking in teenage boys. The main reason for the Adam's apple usually being more prominent in males is that the two laminae of the thyroid cartilage that form the protrusion meet at an angle of 90° in males but that angle is usually 120° in females.
A prominent Adam's apple is commonly considered a male secondary sex characteristic.
For some transwomen and a few men, the Adam's apple is more prominent than desired, and this is sometimes remedied by a chondrolaryngoplasty (trachea shave), a type of plastic surgery to reduce the size of the Adam's apple. This surgery is not without risk as it can adversely affect the voice and cause permanent damage.
The thyroid cartilage is the largest of the nine cartilages that make up the laryngeal skeleton, the cartilage structure in and around the trachea that contains the larynx. It is composed of two plate-like laminae that come together on the anterior side of the cartilage to form a peak, called the laryngeal prominence. This prominence is often referred to as the "Adam's apple". The laryngeal prominence is obvious in both sexes, but it tends to be somewhat more robust in the adult male. The lip of the thyroid cartilage just superior to the laryngeal prominence is called the thyroid notch or superior thyroid notch.
The two laminae that make up the main lateral surfaces of the thyroid cartilage extend obliquely to cover either side of the trachea. The posterior edge of each lamina articulates with the cricoid cartilage inferiorly at a joint called the cricothyroid joint. Movement of the cartilage at this joint produces a change in tension at the vocal folds, which in turn produces variation in voice. The entire superior edge of the thyroid cartilage is attached to the hyoid bone by the thyroid membrane.
The thyroid cartilage forms the bulk of the anterior wall of the larynx, and serves to protect the vocal folds ("vocal cords") which are located directly behind it. It also serves as an attachment for several laryngeal muscles.

A few months ago, I was very sick, zero energy, freezing cold, depressed, weight gain, thought I was dying. I read every word of this Hypothyroidism Revolution program and followed all the advice. My life turned around the first week. I started to feel human again. Within weeks my energy came back and I felt like living again.

It houses the entire vocal mechanism and the Epiglotis, which keeps food from going down your wind pipe.
