The inferior nasal conchae, also known as the inferior turbinate bones, are small, curved bones located within the nasal cavity. These bones are an important part of the respiratory system, as they help to humidify, warm, and filter the air that we breathe.
The inferior nasal conchae are located on either side of the nasal cavity and are attached to the lateral walls of the nasal cavity. They are covered with a thin layer of mucous membrane, which helps to produce and secrete mucus. This mucus helps to moisten the air that we breathe, as well as trapping dust, dirt, and other particles that may be inhaled.
The inferior nasal conchae also play a role in the regulation of air flow through the nasal cavity. They are lined with tiny blood vessels that can expand or contract, depending on the temperature and humidity of the air that we breathe. This allows the inferior nasal conchae to help maintain a consistent and comfortable temperature and humidity within the nasal cavity.
In addition to their role in respiratory function, the inferior nasal conchae are also important for our sense of smell. The olfactory nerve, which is responsible for our sense of smell, is located in the roof of the nasal cavity. The inferior nasal conchae help to direct the flow of air over the olfactory nerve, allowing us to effectively detect and identify different smells.
Overall, the inferior nasal conchae are a crucial part of the respiratory and olfactory systems. They help to humidify, warm, and filter the air that we breathe, as well as aiding in our sense of smell. Without these small but important bones, our respiratory and olfactory systems would not function properly.
Inferior nasal concha
This concha connects directly to the ethmoid and maxillary sinuses. Because the nasal cavity is symmetrical, there are technically pairs of turbinates, leading to 6 in total for an average human. Medial surface It is a convex surface full of small perforations for apertures and marked with longitudinal grooves for accommodating several blood vessels.

This includes vacuuming carpets, pillows, drapes, and furniture to remove dust. The swell bodies literally do swell upon an alternating cycle of every 20—30minutes. The lateral nasal wall usually has three medially directed projections: the superior, middle, and inferior nasal conchae, below each of which is a corresponding superior, middle, or inferior nasal meatus see Figures 10-2 and 10-3.

What does the inferior nasal concha do?
The epithelium that lines the nasal cavities plays a critical role in the overall function of the nose. In medical radiographic images, overall morphology of the bone, anatomical landmarks, trabecular patterns, orientation, placement of foreign materials including bullets or shrapnel and surgical implements, skeletal anomalies, pathological conditions, and evidence of traumatic injury can be used. This filter can help to eliminate a significant amount of irritating dust in a room. Age was estimated based on fetal crown heel length. Unlike the inferior conchae, these are not separate bones, but medial extensions of the labyrinth portion of the ethmoid bone. Septoplasty and turbinate surgery. The lacrimal process of the inferior nasal concha extends superiorly to contribute to the medial wall of the inferior lacrimal canal.

Nasal Concha Explained
What bones form inferior concha? INFERIOR NASAL CONCHA The inferior nasal concha is a spongy curved bone present inside the nose along the outer wall. The trachea extends from the neck into the thorax, where it divides into the right and left main bronchi entering the right and left lung, respectively. What are 3 functions of the conchae? What are 3 main functions of the nasal cavity quizlet? This type of infection is common in people having immunocompromising conditions like HIV, Organ transplant patients, and Diabetes. Functionally, the inferior nasal concha should probably be viewed as a detached piece of the ethmoid bone. A duct that drains tears from the eyes, known as the Nasolacrimal duct, connects to the inferior meatus and drains into the nasal cavity. Because of their appearance under the microscope, they are called goblet cells.

By the time, the air reaches the lungs, its temperature approaches that of the body, and it is nearly saturated with humidity. Filename: Inferior Nasal Concha Surfaces 1. Henry Knipe and Dr. These sinuses are covered by a similar epithelium, but with fewer mucus-producing cells, and they contribute to both the warming and humidification of the air. Inferior nasal conchae function in olfaction and in humidifying inhaled air. Dust adheres to the sticky mucus, and the cilia helps to propel it back up the trachea, where it is either swallowed or coughed out.

Owing to tuberculosis concerns, chest radiographs became a routine procedure across the United States Armed Forces in 1942, unknowingly creating an archive of antemortem radiographs for American soldiers. However, studies of trabecular patterns have shown that the morphology is maintained over time and through subsequent remodeling events. The superior concha serves the role of protecting the olfactory bulb which is important in the sensation of smell. The conchae are also responsible for filtration, heating, and humidification of air inhaled through the nose. Gross anatomy Each inferior nasal concha is a separate facial bone articulating with its respective maxilla and palatine bone. Anatomical variations of nasal turbinates.

What is the function of the nasal conchae?
Studies have shown that features of the vertebral column are individualizing and can be used for scientific identifications. Lymphatic drainage for nasal conchae For lymphatic drainage, lymph from the nasal conchae drains into the submandibular, deep cervical, and retropharyngeal nodes. These may include the use of cryosurgery, radiofrequency ablation, or superficial thermal ablation. Turbinates are also called concha. Inferior nasal conchae function in olfaction and in humidifying inhaled air. This underscores the importance of appropriate forensic training and experience for practitioners to accurately make scientific identifications.

The air could be frigid and dry in a northern winter or very dusty, with even a few flying insects thrown in, during the summer. The swirling allows the air to remain longer in the nose, and that, too, allows for more effective warming. The posterior ethmoidal artery, usually smaller than the anterior ethmoidal artery and absent in up to 30% of the ophthalmic arteries, feeds the mucosa of the posterior ethmoid sinus and the dura of the planum sphenoidale. Conversely, both the middle and superior conchae are part of the ethmoid bone 2. One of the reasons is that constant exposure to flowing air results in metaplasia of the nasal epithelium.

The nasal conchae greatly narrow the width of the nasal chambers and greatly increase the surface area of the walls of the chambers. The trapping function is facilitated by the swirling of air currents in the nose, as well as by electrostatic charges on the mucus, which attract bacteria, pollen, or dust to the mucus. Beyond the tooth structures visible in dental radiographs, other anatomical landmarks are also used to corroborate an identification. The anterior ethmoidal artery, a terminal branch of the ophthalmic artery, supplies the mucosa of the anterior and middle ethmoid sinuses and the dura covering the cribriform plate and the planum sphenoidale. What are the functions of the nasal cavity quizlet? In reality, however, these features are relatively consistent between most individuals and are not always individualizing. In addition to mucus, some of the cells in the mucous glands are specialized to produce a watery serous secretion that enters the nasal chambers and plays an important role in humidifying the air. Nasal Conchae Functions of the nasal conchae The nasal conchae or turbinates are named this way because they function in a similar way as a turbine, being principally responsible for regulating the air flow during inhalation.

Inferior Nasal Conchae Flashcards
Warmth from the flowing blood is dissipated into the air, and changes in the amount of blood flow regulate the degree of warming the air. Yuranga Weerakkody and Dr. Areas that are visible on radiographs and can be used in a point-by-point comparison include the shape of the vertebral bodies, the spinous processes, the transverse processes, the pedicles, intervertebral disc space, and any arthritic lipping or other degenerative changes. Most inhaled airflow travels between the inferior concha and the middle meatus. The Journal of Anatomy. Note, however, that the surface texture of the inferior nasal conchae is highly perforated by numerous tiny apertures, giving them a fragile and lightweight aspect. Turbinate surgery can be difficult because a doctor should not completely remove the turbinates since they serve an important purpose.

In the process of breathing, air enters the nasal cavity through the nostrils and is filtered by coarse hairs vibrissae and mucus. Features of dental radiographs that can be used in forensic identifications include crown and root morphology, tooth angulation, bone trabecular patterns, maxillary sinus morphology, the location and morphology of dental restorations, cavities or other dental pathologies, and missing teeth Figure 1. This process of transformation of one type of cell to another in a tissue is called metaplasia. Computed tomographic anatomy of the canine nasal passages. Forensic anthropologists with training and experience are able to differentiate the distinctive skeletal features that will be useful for a personal identification from those that are commonplace.
