Olfactory
mucosa - plastic section (10x objective lens)
-
This image from a plastic
section from a mammal shows a portion of the olfactory mucosa. The olfactory
mucosa is located in patches in the walls and roof of the nasal passages.
It consists of a pseudostratified columnar epithelium containing three types
of cells: (1) basal cells, which retain the ability
to divide; (2) olfactory cells, which are sensory
bipolar neurons that make up the bulk of the cells present; and (3) supporting
(sustentacular) cells, which provide mechanical and metabolic support
for the olfactory cells. The epithelium rests on a thick lamina propria containing
serous Bowman's glands,
nerves, and blood and lymphatic vessels.
In this preparation the lamina propria is continuous with the perichondrium
of a layer of hyaline cartilage.
