What makes up the pharynx?

The pharynx is divided into three regions according to location: the nasopharynx, the oropharynx, and the laryngopharynx (hypopharynx). The nasopharynx is the portion of the pharynx that is posterior to the nasal cavity and extends inferiorly to the uvula.

What does the pharynx consist of?

The pharynx is composed of mucous membrane, submucosal connective tissue, glands, lymphoid tissue, muscle and an outermost adventitial coating. The mucous membrane does not possess a muscular layer.

What cells make up the pharynx?

oropharynx and laryngopharynx, are lined by nonkeratinizing stratified squamous epithelium.

What two systems make up the pharynx?

The pharynx is part of both the digestive system and the respiratory system.

What are the 3 parts of the pharynx?

The throat (pharynx) is a muscular tube that runs from the back of your nose down into your neck. It contains three sections: the nasopharynx, oropharynx and laryngopharynx, which is also called the hypopharynx.

What are the three parts of the pharynx and their functions?

These parts include the nasopharynx, oropharynx, and laryngopharynx. The nasopharynx is the most superior, or uppermost, part of the pharynx that works with the nasal cavity during breathing. It provides a passageway for air moving from the nose.

Is the pharynx made of cartilage?

Its walls are formed by the thyroid cartilage and the middle and inferior pharyngeal constrictor muscles. The piriform fossa is a depression in the mucous membrane on each side of the inlet.

What is the epithelial cells that lining the pharynx?

The oropharynx and pharynx proper are lined by largely non-keratinizing stratified squamous epithelium. The nasopharynx is mainly lined by ciliated columnar epithelium but stratified squamous epithelium occurs at its lower end where it joins the oropharynx.

What is the blood supply to the pharynx?

The upper part of the pharynx receives blood from the pharyngeal branch of the ascending pharyngeal artery and descending branches of the lesser palatine arteries. The lower part of the pharynx receives blood supply from inferior thyroid artery and superior thyroid artery.

How does the pharynx work in the digestive system?

The pharynx, or throat, is the passageway leading from the mouth and nose to the esophagus and larynx. The pharynx permits the passage of swallowed solids and liquids into the esophagus, or gullet, and conducts air to and from the trachea, or windpipe, during respiration.

What does the pharynx do in the respiratory system?

Pharynx (Throat) The pharynx, usually called the throat, is part of the respiratory system and digestive system. It carries air, food and fluid down from the nose and mouth.

Which part of the pharynx is associated with the digestive system?

The oropharynx is continuous superiorly with the nasopharynx. The laryngopharynx is composed partially of cartilage. It extends from the nasal and oral cavities superiorly to the esophagus anteriorly. The nasopharynx is involved in digestion.

Where does the pharynx start and end?

Definition. The pharynx is a muscular column that begins in the head posterior to the nasal cavity, travels inferiorly behind the oral cavity before finally merging with the larynx and esophagus.

How many openings does the pharynx have?

The pharyngeal cavity has seven (7) openings which are: 1-The paired posterior nose –rostrodorsally which connect nasopharynx with nasal cavity. 2-The paired eustachian tube –dorsolaterally, opening of the auditory tubes, connect the nasopharyngeal with auditory tubes and then middle ear.

What are the three parts of the pharynx and where is each located?

The pharynx is divided into three regions according to location: the nasopharynx, the oropharynx, and the laryngopharynx (hypopharynx). The nasopharynx is the portion of the pharynx that is posterior to the nasal cavity and extends inferiorly to the uvula.
