Figure of pharynx

He also explains how oxygen is carried on … Not all sites, such as cheek, are included in this figure.

At the top of the nasopharynx are the pharyngeal tonsils. Movements of the hyoid are coordinated with movements of the tongue, larynx, and pharynx during swallowing and speaking.

Each of the three pharyngeal constrictors has a left and right part that interdigitate (join in fingerlike branches) in the midline, forming a raphe, or union.

The pharynx: The pharynx is another word for the throat, and the part of the pharynx that is associated with the "r" sound is at the very top of the throat. The pharynx is divided into three regions: the nasopharynx, the oropharynx, and the laryngopharynx. Figure 6.1 shows their location. 23.3 The Mouth, Pharynx, and Esophagus van Loon FPL, Holmes SJ, Sirotkin B, Williams W, Cochi S, Hadler S, Lindegren ML. Divisions of the Pharynx. Normal pharynx as viewed with an endoscope, demonstrating the junction of the hard and soft palate, uvula, and posterior pharynx. The pharynx is a conductive structure located in the midline of the neck. When exceptionally large the sphenoid sinuses may extend into the roots of the pterygoid processes or great wings, and may invade the basilar part of the occipital bone.. Each sinus opens into the roof of the nasal cavity via apertures on the posterior wall of the sphenoethmoidal recess directly above the choana.The apertures are located high on the anterior walls of the sinuses themselves.

The pharynx is divided into three major regions: the nasopharynx, the oropharynx, and the laryngopharynx (Figure 22.6). The nasopharynx is flanked by the conchae of the nasal cavity, and it serves only as an airway.

Cancers of the head and neck include cancers that start in several places in the head and throat, not including brain cancers or cancers of the eye.


Elevates pharynx and larynx 3. The pharynx is divided into 3 parts including the nasopharynx, oropharynx, and hypopharynx (Figure 1). Figure 6.1. Crash Course Biology is now available on DVD!

The pharynx is divided into three regions: the nasopharynx, the oropharynx, and the laryngopharynx. The pharynx is a tube formed by skeletal muscle and lined by mucous membrane that is continuous with that of the nasal cavities (see Figure 22.4). Pharynx. Morbidity and Mortality Weekly Report: Mumps surveillance -- United States, 1988–1993 [Internet].

With the endoscope advanced under direct vision, the inferior portion of the uvula is seen at the base of the tongue. Figure 5. A lateral pharyngeal diverticulum is a protrusion of nonkeratinizing squamous mucosa originating in the pharynx. He then tours the major organs of the respiratory system; from the pharynx to the trachea, bronchus, bronchiole and alveoli.

When it is raised so that the soft palate is pressed against the back wall of the pharynx there is said to be a velic closure. It is the main structure, in addition to the oral cavity, shared by two organ systems, i.e., the gastrointestinal tract (GIT) and the respiratory system.

The pharynx is the intermediate part of the upper aerodigestive tract in the head and neck region, connecting the nasal cavity to the lower airway thru the larynx and the oral cavity to the esophagus.

This raphe forms the back wall of the pharynx.

It is divided into three contiguous anatomic regions: the nasopharynx, oropharynx, and hypopharynx ( Fig. A: Incidence rates for oropharyngeal cancer (overall), HPV-positive oropharyngeal cancer, and HPV-negative oropharyngeal cancer. Opens auditory tube when swallowing 4.
