Detailed explanation-1: -The throat (pharynx and larynx) is a ring-like muscular tube that acts as the passageway for air, food and liquid. It is located behind the nose and mouth and connects the mouth (oral cavity) and nose to the breathing passages (trachea [windpipe] and lungs) and the esophagus (eating tube).

Detailed explanation-2: -The three parts of the pharynx are the nasopharynx, oropharynx, and hypopharynx.

Detailed explanation-3: -The connective tissue, cartilage, and smooth muscle of these structures develop from the splanchnic mesenchyme surrounding the foregut. The endoderm lining the laryngotracheal tube gives rise to the epithelium and glands of the larynx and trachea.

Detailed explanation-4: -Regionally, the pharynx divides into three parts which are from superior to inferior:-the nasal pharynx, located behind the posterior nasal apertures (choanae), the oral pharynx, located behind the opening of the oral cavity, and the laryngeal pharynx, located behind the inlet (opening) of the larynx.
