Anatomy Head And Neck Laryngopharynx Statpearls Ncbi Bookshelf The laryngopharynx, also referred to as the hypopharynx, is the most caudal portion of the pharynx and is a crucial connection point through which food, water, and air pass. specifically, it refers to the point at which the pharynx divides anteriorly into the larynx and posteriorly into the esophagus. the act of swallowing, or deglutination, is a complex multistep process performed by several. The larynx is a cartilaginous segment of the respiratory tract located in the anterior aspect of the neck. the primary function of the larynx in humans and other vertebrates is to protect the lower respiratory tract from aspirating food into the trachea while breathing. it also contains the vocal cords and functions as a voice box for producing sounds, i.e., phonation. from a phylogenetic view.

The laryngopharynx is a clinically important anatomical location because of the high proportion of pharyngeal cancers that originate there. the pyriform sinus is the most frequent site of laryngopharyngeal cancer, with squamous cell carcinoma accounting for 95% of cases. the laryngopharynx is also clinically relevant due to a disorder related.

The pharynx is the digestive system posterior to the nasal cavity, oral cavity, and larynx and divides into the oropharynx, nasopharynx, and laryngopharynx. a group of muscles called the pharyngeal muscles, which consist of the outer circular layer and the inner longitudinal layer, forms the lumen o ….

The neck is the bridge between the head and the rest of the body. it is located in between the mandible and the clavicle, connecting the head directly to the torso, and contains numerous vital structures. it contains some of the most complex and intricate anatomy in the body and is comprised of numerous organs and tissues with essential structure and function for normal physiology. structures. The arches are located in between the pouches and clefts and develop into the mesoderm, which eventually forms the cartilage, muscles, and nerves of the head and neck. the fourth and sixth arches develop into the cartilaginous structures that make up the larynx, which includes the arytenoids, cricoid, cuneiform, and thyroid cartilage.
