PHARYNX ANATOMY Positioned above the mouth (which is the entryway point for nourishment) is the nasopharynx. This is the only entryway for air alone. The mouth serves both the digestive and the respiratory system. Situated directly behind the nasal cavity and just above the soft palate, this is the highest point of the pharynx.The uvula, which is the pendulum-like fixture that hangs above the opening of the esophagus, dangles from the middle lower segment of the soft palate.ttp://www.medicalook.com. SEARCH. The pharynx is responsible for adjoining the nasal cavity and the oral cavity to the larynx (which belongs to the respiratory system) and the esophagus (which belongs to the digestive system.

Nose Anatomically, a nose is a protuberance in vertebrates that houses the nostrils, or nares, which admit and expel air for respiration in conjunction with the mouth. Behind the nose are the olfactory mucosa and the sinuses. Behind the nasal cavity, air next passes through the pharynx, shared with the digestive system, and then into the rest of the respiratory system. In humans, the nose is located centrally on the face and serves as an alternative respiratory passage especially during suckling for infants. On most other mammals, it is located on the upper tip of the snout.

Anatomy and Physiology of the Nasal Cavity (Inner Nose) and Mucosa Introduction. The nasal cavity refers to the interior of the nose, or the structure which opens exteriorly at the nostrils. It is the entry point for inspired air and the first of a series of structures which form the respiratory system.he nasal cavity functions to allow air to enter the respiratory system upon respiration. Structures within the cavity regulate the flow of air and particles it contains. The olfactory region of the nasal cavity regulates the sense of smell.

- The oral cavity begins at the lips and extends back to the beginning of the tonsils. The bones of the lower jaw (mandible) and upper jaw (hard palate) are included in this region. The oral cavity also includes: The floor of the mouth, situated directly behind the lower teeth in what looks like a smooth gutter.

Body cavity The dorsal cavity includes the cranial and spinal cavities. 1  The cranial cavity is a large, bean-shaped cavity filling most of the upper skull where the brain is located. 2  The vertebral cavity is a very narrow, thread-like cavity running from the cranial cavity down the entire length of the spinal cord.

Body cavity Together the cranial cavity and vertebral cavity can be referred to as the dorsal body cavity. In the posterior (dorsal) cavity, the cranial cavity houses the brain, and the spinal cavity (or vertebral cavity) encloses the spinal cord.Just as the brain and spinal cord make up a continuous, uninterrupted structure, the cranial and spinal cavities that house them are also continuous. The two pleural cavities are situated on both sides of the body, anterior to the spine and lateral to the breastbone. 2  The superior mediastinum is a wedge-shaped cavity located between the superior regions of the two thoracic cavities.

The Ethmoid Bone The cribriform plate (Latin “cribriform” = perforated) lies within the ethmoidal notch of the frontal bone and forms the roof of the nasal cavity. As the name suggests it comprises numerous openings through which the olfactory fibers from the nasal cavity pass through to the anterior cranial fossa.he cribriform plate (Latin “cribriform” = perforated) lies within the ethmoidal notch of the frontal bone and forms the roof of the nasal cavity.

Pharynx The pharynx consists of three main divisions. 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. The oral pharynx begins at the back of the mouth cavity and continues down the throat to the epiglottis, a flap of tissue that covers the air passage to the lungs and that channels food to the esophagus.

1. ANATOMY OF THE ORAL CAVITY. The mouth is that part of the body bounded by the cheeks, lips, palate, and the floor of the mouth (the area beneath the tongue). The nasal cavity is located above the mouth and is separated from the mouth by the hard and soft palate.

Maxilla Home > Skeletal System > Bones of the Head and Neck > Maxilla. The maxilla consists of maxillary bones that form the upper jaw; together they are the keystone of the face, for all other immovable facial bones are connected to them. Portions of these bones make up the front of the roof of the mouth (hard palate), the floors of the orbits, and the sides and floor of the nasal cavity. They also contain the sockets of the upper teeth. Inside the maxillae, on the sides the nasal cavity, are the maxillary sinuses (antrum of Highmore). These air-filled spaces are the largest of the sinuses, and they extend from the floor of the orbits to the roots of the upper teeth.

Nasal Cavity - Anatomy & Physiology The nasal cavity is occupied to a large extent by nasal conchae. These are turbinate bones which project into the nasal cavity with the purpose of supporting the olfactory mucus membranes and increasing the respiratory surface area, creating turbulence within the passing air.he respiratory tract begins with the nose which includes the external nose, internal nasal cavities and paranasal sinuses. As well as being vital for transport of gases to the lower respiratory tract, the nasal cavity is also the site for one of the special senses-Olfaction.

Overview This development places the floor of the sinus well below the floor of the nasal cavity. The shape of the sinus is a pyramid, with the base along the nasal wall and the apex pointing laterally toward the zygoma. The natural ostium of the maxillary sinus is located in the superior portion of the medial wall.

Sore Throat 101: Symptoms, Causes, and Treatment A sore throat can feel: scratchy; burning; raw; dry; tender; irritated; It may hurt more when you swallow or talk. Your throat or tonsils might also look red. Sometimes, white patches or areas of pus will form on the tonsils. These white patches are more common in strep throat than in a sore throat caused by a virus.

Pharynx The pharynx makes up the part of the throat situated immediately behind the nasal cavity, behind the mouth and above the esophagus and larynx. The human pharynx is conventionally divided into three sections: the nasopharynx, the oropharynx and the laryngopharynx. It is also important in vocalization. In humans there are two sets of pharyngeal muscles that form the pharynx, determining the shape of its lumen.

Nasopharynx The soft palate separates the nasopharynx from the oropharynx, which sits just below the soft palate. The nasopharynx remains open even when surrounding muscles flex so that the person can continue to carry on respiratory functions.he nasopharynx is 2 to 3 cm wide and 3 to 4 cm long and situated behind the nasal fossa inside the occipital bone. The nasopharynx is the space above the soft palate at the back of the nose and connects the nose to the mouth, which allows a person to breathe through the nose.

Mouth The throat, or pharynx, is a funnel-shaped tube located in the posterior of the mouth. The pharynx connects the nasal cavity and mouth to the esophagus and larynx in the neck. The region of the throat behind the mouth is known as the oropharynx and forms the posterior wall of the mouth.
