Nasal cavity

Slide 108: Olfactory epithelium

H/E

This slide is a section through the olfactory epithelium of the respiratory section of the nasal cavity of an embryo.

Identify:

Macroscopic

  • Nasal septum

  • Nasal cavities

  • Conchae

Microscopic

  • Olfactory epithelium

  • Lamina propria

 

Draw and annotate:

The olfactory epithelium, the glands of Bowman and the lamina propria.

 

Reflection:
  1. What cells form the epithelium?
  2. What type of connective tissue is found here and which outstanding structures are found here?
  3. What is the next layer on which the lamina propria lies?
