There are typically three pairs of turbinates in the human nose - the inferior concha, the middle concha and the superior concha. Each pair is very different in size and in shape, and each protect a different region of the nasal cavity: The inferior turbinates are the largest and extend all across the lower part of the nasal cavity, from the very front of the nose almost up to the nasopharynx.
