GENERAL CHARACTERISTICS

  • Scroll-shaped bone with a distinctive curved morphology
  • Located on the lateral wall of the nasal cavity
  • Paired structure — one on each side of the nasal septum

FUNCTIONAL SIGNIFICANCE

  • Increases surface area within the nasal cavity
  • Assists in warming inhaled air
  • Assists in humidifying inhaled air
  • Important role in the respiratory system

  • Bones that articulate with the inferior nasal concha:
    • Lacrimal bone
    • Ethmoid bone
    • Palatine bone
    • Maxilla
  • Contributes to the architecture of the nasal cavity

PROCESSES

Maxillary Process

  • Lateral extension of the inferior nasal concha
  • Articulates with the maxilla
  • Contributes to formation of maxillary sinus wall
  • Integrates the concha into the facial skeleton
  • Provides structural support to the sinus

QUICK FACTS: INFERIOR NASAL CONCHA

Key questions answered about this anatomy topic

Q: What is the inferior nasal concha?

Answer: An independent paired facial bone in the nasal cavity. The inferior nasal concha is an independent paired facial bone located on the lateral wall of the nasal cavity. Unlike the superior and middle conchae which are parts of the ethmoid bone, the inferior nasal concha is a separate bone.

Q: Is the inferior nasal concha a separate bone or part of another bone?

Answer: It is a separate, independent bone. The inferior nasal concha is a separate, independent bone. This distinguishes it from the superior and middle nasal conchae, which are projections of the ethmoid bone. It is the largest of the three nasal conchae.

Q: How many inferior nasal conchae are there in the skull?

Answer: Two (paired). There are two inferior nasal conchae in the skull - one on each side of the nasal septum. They are paired bones that mirror each other on the lateral walls of the nasal cavity.

Q: What is the function of the inferior nasal concha?

Answer: To warm, humidify, and filter inhaled air. The inferior nasal concha functions to warm, humidify, and filter inhaled air. Its scroll-shaped structure increases surface area within the nasal cavity, allowing the mucosa to efficiently condition inspired air before it reaches the lungs.

Q: Is the inferior nasal concha a cranial or facial bone?

Answer: Facial bone (viscerocranium). The inferior nasal concha is classified as a facial bone (viscerocranium). It is one of the 14 facial bones and contributes to the structure of the nasal cavity rather than the cranial vault.
