Nasal bone & nasal cavity

  1. 1. Nasal Bone & Nasal Cavity Present by M.Anandha Prabhakaran Department of Biotechnology Periyar Maniammai University
  2. 2. Nasal Bone• The nasal bones are two small, and different in individuals.• Lie between maxillary bones and join to form the bridge of the nose.• Attach to cartilaginous tissues - shape for nose.
  3. 3. Nasal Cavity• Function• Segments• Blood supply• Innervation
  4. 4. Function• Air passing through the nasal cavity is warmed or cooled to within 1 degree of body temperature.• Dust and other particulate matter is removed by vibrissae.
  5. 5. Segments• Respiratory segment: Mainly for air flow In and Out by epithelium tissue• Olfactory segment: Sense for smell
  6. 6. Nerve in nasal cavitySensory: – Nasociliary nerve (V1) – Nasopalatine nerve (V2) – Posterior nasal branches of Maxillary nerve (V2)
