Pharyngeal pouch (embryology) In the embryonic development of vertebrates, pharyngeal pouches form on the endodermal side between the pharyngeal arches. The pharyngeal grooves (or clefts) form the lateral ectodermal surface of the neck region to separate the arches.The pouches line up with the clefts, and these thin segments become gills in fish.n the embryonic development of vertebrates, pharyngeal pouches form on the endodermal side between the pharyngeal arches.

Guttural Pouch Empyema & Chondroids The guttural pouches are paired outpocketings of the upper airway (pharynx). They are located near the throatlatch region of the neck. Major vessels and nerves supplying the head course through the walls of the pouch. The pouch is accessed with an endoscope through a small slit in the pharynx. The guttural pouches are thought to be involved in cooling blood that passes to the brain through the large carotid arteries. They may also have a role in equalizing air pressure on the tympanic membrane.

- Posterior pharyngeal pulsion (Zenker's) diverticulum: Zenker called this pulsion diverticula. Earlier foreign body impaction was attributed as a cause of this diverticulum. Killian attributed spasmodic contraction of the circular fibers at the upper end of the esophagus.efinition: Pharyngeal pouches are mainly acquired and rarely congenital diverticula in and around the pharynx and oesophagus. These diverticula are nothing but circumscribed pouches caused by a protrusion of mucosa through a preexisting weakness / opening in the muscle layers of pharynx / oesophagus.

Pharynx In humans the pharynx is part of the digestive system and also of the conducting zone of the respiratory system. The conducting zone also includes the nose, larynx, trachea, bronchi, and bronchioles, and their function is to filter, warm, and moisten air and conduct it into the lungs.he upper portion of the pharynx, the nasopharynx, extends from the base of the skull to the upper surface of the soft palate. It includes the space between the internal nares and the soft palate and lies above the oral cavity.

What is the Pharynx and Tonsils? Function, Location, Pictures The pharynx is the uppermost part of the alimentary tract and commonly referred to as the throat. It directs the passage of air and food between the mouth and nose into esophagus and larynx. The tonsils are collections of lymphoid tissue that lie in the pharynx.he oropharynx extends from the back of the mouth and carries ingested food and drinks from the mouth into the esophagus. The laryngopharynx lies just behind the larynx (voice box) and is the lowermost part of the pharynx. It serves as a common passage for both food (into the esophagus) and air (into the larynx).

HISTOLOGICAL FEATURES OF TONSIL Waldeyer's Ring of Lymphoid Tissue. The lymphoid tissue that surrounds the opening into the respiratory and digestive systems forms a ring. The lateral part of the ring is formed by the palatine tonsils and tubal tonsils (lymphoid tissue around the opening of the auditory tube in the lateral wall of the nasopharynx).he tonsils constitute a lymphoid tissue that lies beneath, and in contact with, the epithelium of the initial portion of the digestive tract. Depending on their location, tonsils in the mouth and pharynx are called palatine, pharyngeal, or lingual.
