What does the pharynx connects the nasal cavity to?
The Pharynx Connects the Nasal and Oral Cavities to the Larynx and Esophagus. The pharynx, or throat, is shaped like a funnel. During respiration, it conducts air between the larynx and trachea (or “windpipe”) and the nasal and the oral cavities.
What structure separates the nasal cavity and the pharynx?
Anatomy of the nasal cavity The nasal cavity extends from the external opening, the nostrils, to the pharynx (the upper section of the throat), where it joins the remainder of the respiratory system. It is separated down the middle by the nasal septum, a piece of cartilage which shapes and separates the nostrils.
What connects nasal cavity with throat?
Pharynx — is the muscle-lined space that connects the nose and mouth to the larynx and esophagus (eating tube). Larynx — also known as the voice box, the larynx is a cylindrical grouping of cartilages, muscles and soft tissue that contains the vocal cords.
What is the opening to the pharynx from the nasal cavity called?
Air enters the nasal cavity from the outside through two openings: the nostrils or external nares. The openings from the nasal cavity into the pharynx are the internal nares.
What separates the pharynx from the larynx?
The pharynx is a space that connects the mouth with the esophagus, and the nasal cavity with the larynx. The soft palate divides the pharynx into the nasopharynx dorsally and the oropharynx ventrally. The oropharynx is divided into the isthmus of fauces (throat opening) and a laryngeal part.
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.
Why is the nasal cavity divided?
The nasal cavity is divided in two by the vertical nasal septum. These turbinates disrupt the airflow, directing air toward the olfactory epithelium on the surface of the turbinates and the septum. The vomeronasal organ is located at the back of the septum and has a role in pheromone detection.
What is the nasal pharynx?
pharynx, (Greek: “throat”) cone-shaped passageway leading from the oral and nasal cavities in the head to the esophagus and larynx. The anterior portion is the nasal pharynx, the back section of the nasal cavity. The nasal pharynx connects to the second region, the oral pharynx, by means of a passage called an isthmus.
What separates the nasal cavity?
The nasal septum divides the cavity into two cavities, also known as fossae. Each cavity is the continuation of one of the two nostrils.
What cavity is the pharynx located in?
The pharynx (plural: pharynges) is the part of the throat behind the mouth and nasal cavity, and above the oesophagus and trachea (the tubes going down to the stomach and the lungs). It is found in vertebrates and invertebrates, though its structure varies across species….

What is located in 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.
