The inferior nasal concha is ossified from a single center, which appears about the fifth month of fetal life in the lateral wall of the cartilaginous nasal capsule. [citation needed] The entire inferior concha may be absent in some people. This is a consequence of embryologic agenesis and is a normal anatomic variant. Clinical significance Concha nasalis inferior 1/3 Synonyms: Inferior nasal turbinate The nasal conchae (also known as turbinates) are bony plates located on the lateral wall of the nasal cavity. There are three nasal conchae in each nasal cavity including the superior, middle and inferior nasal conchae.
Inferior Nasal Concha Anatomy, Definition & Development Kenhub
Anatomy The inferior nasal conchae are a pair of bones, with one concha on either side, that separates the middle and lower nasal meatus, or nasal cavity. They are often described as being "spongy" bones. While the superior and middle nasal conchae are technically part of the ethmoid bone, the inferior nasal concha forms a completely separate bone. A concha is any of the scrolled spongy bones of the nasal passages in vertebrates. [3] In humans, the conchae divide the nasal airway into four groove-like air passages, and are responsible for forcing inhaled air to flow in a steady, regular pattern around the largest possible surface area of nasal mucosa. The inferior nasal conchae are considered a pair of facial bones since they articulate with their respective maxillae bones and project horizontally into the nasal cavity. Superior to the inferior nasal conchae are the middle nasal conchae and superior nasal conchae. The inferior nasal concha, also known as the inferior turbinate or the lower nasal concha, is a small bone located within the nasal cavity of the human body. It is one of the three paired nasal conchae, which are thin, curved bones that project from the lateral wall of the nasal cavity.

What is the Inferior Nasal Concha The inferior nasal concha is a small, paired facial bone. It is one of the three bony structures that form the lateral wall of the nasal cavity, the other two being the superior and middle conchae. Unlike these two, the inferior nasal concha is an independent bone in the skull. Where is it located Concha nasalis inferior Quick Facts Key Features & Anatomical Relations Ossification Variations List of Clinical Correlates References Quick Facts Location: Viscerocranium. Bone Type: Irregular bone. Key Features: Medial and lateral surfaces, superior and inferior borders, and lacrimal, maxillary, and ethmoidal processes. The are three conchae - inferior, middle and superior. They project into the nasal cavity, creating four pathways for the air to flow. These pathways are called meatuses: Inferior meatus - between the inferior concha and floor of the nasal cavity. Middle meatus - between the inferior and middle concha. Located along the lateral walls of the nasal cavity, there are three pairs of turbinates commonly described: superior, middle, and inferior.[1] Additionally, between 8% and 80% of patients will possess either a unilateral or bilateral supreme turbinate as well.[2][3] The bony components of the turbinates are referred to as conchae; the conchae of the middle, superior, and supreme turbinates.
Concha nasalis inferior
The inferior nasal concha is one of the three paired nasal conchae in the nose. It extends horizontally along the lateral wall of the nasal cavity and consists of a lamina of spongy bone, curled upon itself like a scroll, . The inferior nasal conchae are considered a pair of facial bones. As the air passes through the turbinates, the air is churned against these mucosa-lined bones in order to. The middle and superior conchae are part of the ethmoid bone, whereas the inferior concha is a separate bone altogether. There is a normal variant called the supreme conchae.. Climatic adaptation in human inferior nasal turbinate morphology: Evidence from Arctic and equatorial populations. Am J Phys Anthropol. 2019 Jul; 169 (3):498-512.
The inferior nasal concha (also called the inferior turbinate, inferior nasal turbinate, Latin: concha nasi inferior, concha nasalis inferior) is a paired bone in a form of a horizontal curved plate situated in the lateral wall of the nasal cavity. Concha nasalis inferior Synonym: Inferior nasal turbinate Related terms: Inferior nasal concha Definition The inferior nasal concha extends horizontally along the lateral wall of the nasal cavity and consists of a lamina of spongy bone, curled upon itself like a scroll. It has two surfaces, two borders, and two extremities. Gallery
Middle Nasal Concha The Respiratory System
Inferior nasal concha definition The largest of the three turbinate bones, the inferior conchae or inferior turbinates are a pair of identical bones, covered in a thick mucus layer, located below the superior and middle conchae [1, 2]. The inferior nasal conchae (inferior turbinated bone or inferior turbinal/turbinate) is a bone inside the nose. There are three of them inside your nose. It goes along the side wall of the nasal cavity. It is a lamina of spongy bone, curled upon itself like a scroll, (turbinate meaning inverted cone). : Head (body part)
