What is the structure of the pharynx?

pharynx, (Greek: “throat”) cone-shaped passageway leading from the oral and nasal cavities in the head to the esophagus and larynx. The pharynx chamber serves both respiratory and digestive functions. Thick fibres of muscle and connective tissue attach the pharynx to the base of the skull and surrounding structures.

What are the three structures of the pharynx throat )?

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 major structures of the mouth and pharynx?

The pharynx is the cavity which connects the nose and the mouth to the larynx and the esophagus. It is divided into 3 sections, the nasopharynx, oropharynx and laryngopharynx. The nasopharynx runs from the back of the nasal cavity down the posterior aspect of the soft palate.

What is the structure and function of the pharynx?

pharynx, (Greek: “throat”) cone-shaped passageway leading from the oral and nasal cavities in the head to the esophagus and larynx. The pharynx chamber serves both respiratory and digestive functions. Thick fibres of muscle and connective tissue attach the pharynx to the base of the skull and surrounding structures.

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.

What is the pharynx?

The hollow tube inside the neck that starts behind the nose and ends at the top of the trachea (windpipe) and esophagus (the tube that goes to the stomach). The pharynx is about 5 inches long, depending on body size. Also called throat.

What are the three functions of the pharynx?

The pharynx, commonly called the throat, is a passageway that extends from the base of the skull to the level of the sixth cervical vertebra. It serves both the respiratory and digestive systems by receiving air from the nasal cavity and air, food, and water from the oral cavity.

What is the pharynx and larynx?

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).

What structures form the boundary of the pharynx?

The boundaries of the pharynx are the mouth and the nasal choanae anteriorly; the soft palate, or velum, and portions of the skull base superiorly; the posterior tongue inferiorly; and the pharyngeal constrictors posteriorly.

What is the structure of mouth?

Parts of the mouth include the lips, vestibule, mouth cavity, gums, teeth, hard and soft palate, tongue and salivary glands. The mouth is also known as the oral cavity or the buccal cavity.

What does the pharynx secrete?

The lining of the pharynx secretes mucus to lubricate the pharynx and helps in smooth propulsion of food down to the esophagus and reduce throat irritation.

What is the function of pharynx?

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.

What is the function of the pharynx in respiration?

The pharynx acts as a passageway for food on its way to the stomach and for air en route to the lungs. The mucosal epithelium in the pharynx is thicker than elsewhere in the respiratory tract as it has to protect the tissues from any abrasive and chemical trauma caused by food.

Is the pharynx part of the respiratory system?

The pharynx is part of the digestive system as well as the respiratory system because it carries both food and air.

Which structure of the respiratory system connects the pharynx to the trachea bronchi larynx nasal cavity lungs?

The larynx connects the lower part of the pharynx, the laryngopharynx, to the trachea.

Where is the posterior pharynx?

The posterior aspect of the pharynx is lined by the posterior pharyngeal wall and soft tissue that covers the cervical spine. The tongue is retracted by the mouth gag and is visible in the top of the picture. The base of tongue forms the base of the pharynx. The base of tongue contains the lingual tonsils.
