In some areas there is. The midline prominence of the nose extending from the nasal root to the tip also called the dorsum of the nose. The auricle or pinna and the external acoustic meatus which ends at the tympanic membrane.

The first portion of the respiratory tract is made up of the nose or external nose and an open inner chamber called the nasal cavity. Each canal opens to the face by a nostril and into. On each side it is flanked by the maxillary sinuses and roofed by the frontal ethmoid and sphenoid sinuses in an anterior to posterior fashion1 While seemingly simple sinonasal anatomy is composed of.

It is a pyramidal structure with its root located superiorly and apex sitting inferiorlyThe root is continuous with the anterior surface of the head and the part between the root and the apex is called the dorsum of the nose. The bones are called. A dynamic layer of mucus overlies the nasal epithelium the outermost layer of.

Air comes into the body through the nose. The cartilage also gives. They interconnect ribs and are therefore the primary respiratory skeletal muscles.

Anatomy of the nasal mucosa. The nose is the bodys primary organ of smell and also functions as part of the bodys respiratory system. A canal that links the middle ear with the back of the nose.

The tympanic membrane divides the external ear from the middle ear. Its primary function is to protect the lower airway by closing abruptly upon mechanical stimulation thereby halting respiration and preventing the entry of foreign matter into the airway. The external genitalia include the labia majora mons pubis labia minora clitoris and glands within the vestibule.

Anatomy of the Nose The External Nose. The variance in shape depends on the shape of the ethmoid bone which is an anterior cranial bone located between the eyes. The nasal cavity is a roughly cylindrical midline airway passage that extends from the nasal ala anteriorly to the choana posteriorly1 It is divided in the midline by the nasal septum.

Upper 23 is thin Lessard et al 1985. The external nasal anatomy is quite simple. This article will discuss the anatomy of the external nose its skeletal structure muscles blood supply and innervation.

The larynx is located within the anterior aspect of the neck anterior to the inferior portion of the pharynx and superior to the trachea. The external genitalia are the accessory structures of the female reproductive system that are external to the vagina. Ventilation or breathing is the movement of air through the conducting passages between the atmosphere and the lungsThe air moves through the passages because of pressure gradients that are produced by contraction of the.
