What 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.
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 is the most posterior part of the pharynx?
The oropharynx is the portion of the pharynx that is posterior to the oral cavity.
What is the anatomy 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 should the pharynx look like?
The surface may be smooth or appear to have small coral pink to translucent, gelatin-like, homogenous surface prominences which are consistent with normal areas of scattered lymph tissues (lymphoid aggregates).
Where is the posterior nasopharynx?
nasal cavity
The nasopharynx is located posterior to the nasal cavity which is lined by pseudostratified columnar epithelium. It communicates with the nasal cavities through the nasal choanae and with the middle ear through the eustachian tube. It also contains the pharyngeal tonsils (adenoids) in its posterior wall.
Where is your pharynx located?
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 tissue is the pharynx made 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 happens if the pharynx is damaged?
The damage can range from minor vocal cord weakness to fractures of the cartilage structures of the larynx or trachea. These fractures can cause air to escape into the neck and chest, leading to significant respiratory compromise and even death if not diagnosed and treated quickly.
What organs are found in the nasopharynx?
The nasopharynx represents the most superior portion of the pharynx, bounded superiorly by the skull base and inferiorly by the soft palate. The nasopharynx connects the nasal cavity to the oropharynx and contains the Eustachian tube openings and adenoids.
What are the 3 parts of the pharynx from superior to inferior?
Regionally, the pharynx divides into three parts which are from superior to inferior:-the nasal pharynx, located behind the posterior nasal apertures (choanae), the oral pharynx, located behind the opening of the oral cavity, and the laryngeal pharynx, located behind the inlet (opening) of the larynx.
What color is the pharynx?
The tissue in this area should appear very vascular but otherwise homogenous in color tending towards reddish pink (Figure 25).
