Anatomy III Respiratory System Connects the nasal cavity with the rest of the pharynx. Behind the soft palate and has two openings from the nose (posterior nares) and the passageways connecting the ears (eustachian tubes or pharyngotympanic tubes). structure of the respiratory system that consists of two nasal cavities separated by the nasal septum, anterior nares, posterior nares, ridges in the nose called the nasal concha (or turbinate bones).

Pharynx The oropharynx lies behind the oral cavity, extending from the uvula to the level of the hyoid bone. It opens anteriorly, through the isthmus faucium, into the mouth, while in its lateral wall, between the palatoglossal arch and the palatopharyngeal arch, is the palatine tonsil.

soft palate When the soft palate rises, as in swallowing and in sucking, it separates the nasal cavity and the nasopharynx from the posterior part of the oral cavity and the oral part of the pharynx.The posterior border of the soft palate hangs like a curtain between the mouth and the pharynx.hen the soft palate rises, as in swallowing, it separates the nasal cavity and nasopharynx from the posterior part of the oral cavity and oral portion of the pharynx. In sucking the soft palate and posterior superior surface of the tongue occlude the oral cavity from the orapharynx, creating a posterior seal.

Pharynx â Functions, Anatomy, Pictures, Disorders Pharynx is a vertical tube lying behind the nasal and oral cavity. Its walls are built from striated (voluntary) muscles, covered by mucosal layer on its inner side. The part of the pharynx lying behind the nasal cavity is called the nasopharynx (Lat. nasus = nose).

Anatomy and Physiology of the Nasal Cavity (Inner Nose) and Mucosa The sinuses develop as outgrowths of, and drain into, the nasal cavity. The mucosa of the sinuses connects to the nasal mucosa. Nasolacrimal ducts. Nasolacrimal ducts are the ducts which connect the lacrimal (tear) ducts in the eye to the nasal cavity.

Nasal passageway The nasal cavity is the air passage starting at the nostril (opening of the nose) and ending at the back of the throat(4). Nasal Obstruction is a partial or complete blockage of one or both of these air passages. The nose is one of the few openings of the body for bacteria and microbes to go inside the body.

- The nasal passage joins to the larynx by the pharynx. The pharynx is about 15cm long in an adult horse. This includes the naspharynx, which protects the entrance to the auditory tubes, the oropharynx, which contains the tonsilar tissue, and the laryngopharynx.

The Pharynx Fig 1.0 – The pharynx in relation to the nasal and oral cavities. The pharynx is a muscular tube that connects the nasal cavities to the larynx and oesophagus.It is common to both the alimentary and the respiratory tract. The tube begins at the base of the skull and ends inferior to the cricoid cartilage (C6).he most distal part of the pharynx, this is located between the superior border of the epiglottis and inferior border of the cricoid cartilage (C6), at which point it becomes continuous with the oesophagus.

What Are Nasal Cavity and Paranasal Sinus Cancers? The nasal cavity. The nose opens into the nasal passageway, or cavity. This cavity is a space that runs along the top of the roof of the mouth (the palate, which separates your nose from your mouth) and then turns downward to join the passage from the mouth to the throat.he nasal cavity and the paranasal sinuses are lined by a layer of mucus-producing tissue called mucosa. The mucosa has many types of cells, including: 1  Squamous epithelial cells, which are flat cells that line the sinuses and make up most of the mucosa.

Pharynx It makes up the part of the throat situated immediately posterior to the nasal cavity, posterior to the mouth and superior to 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.he oropharynx lies behind the oral cavity, extending from the uvula to the level of the hyoid bone. It opens anteriorly, through the isthmus faucium, into the mouth, while in its lateral wall, between the palatoglossal arch and the palatopharyngeal arch, is the palatine tonsil.

Nasal Cavity - Anatomy & Physiology The 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.

How Long Is the Great Wall of China? â 21,196 Kilometers Wan means 10,000, and a li is half a kilometer. So 10,000 li is 5,000 km (3,100 miles), which was a actually a good estimation of the Great Wall length in the Qin Dynasty. However it continued in use through future dynasties, despite the Great Wall becoming longer.

pelvic cavity The common meatus is the narrow, vertical passage close to the nasal septum. The rostral end of the cavity just inside the nostril is the nasal vestibule, and the caudal part opening into the pharynx is the nasopharyngeal meatus. the cavity of the mouth, made up of a vestibule and oral cavity proper.

Selner's Rhinolaryngoscopy Online Chapter 3. NORMAL ANATOMY OF THE UPPER AIRWAY Chapter 3. NORMAL ANATOMY OF THE UPPER AIRWAY. For convenience in the study of anatomy and pathology, the upper airway may be divided into sections (Figure 1). In adults, the nasal cavity is a channel approximately nine to ten centimeters in length from the meatus to the choana. The choana (posterior naris) separates the nasal cavity from the nasopharynx.

What Are Nasal Cavity and Paranasal Sinus Cancers? The nose opens into the nasal passageway, or cavity. This cavity is a space that runs along the top of the roof of the mouth (the palate, which separates your nose from your mouth) and then turns downward to join the passage from the mouth to the throat. Sinuses are cavities (spaces) or small tunnels.

Overview Overview. The eustachian tube (pharyngotympanic tube) connects the middle ear cavity with the nasopharynx. It aerates the middle ear system and clears mucus from the middle ear into the nasopharynx. Opening and closing functions of the eustachian tube are physiologically and pathologically important.
