Question

what structure is highlighted?

a. bowmans glands
b. nucleus of supporting cell of olfactory epithelium
c. nucleus of olfactory neuron (cn i)
d. insular lobe
e. nucleus of basal cell of olfactory epithelium

Explanation:

Identify the tissue type

The histology image shows a pseudostratified columnar epithelium with specialized cells, characteristic of the olfactory epithelium.

Analyze the highlighted structure

Using the Olfactory Pathway Anatomy knowledge point
The highlighted green structure is a duct-like tubule extending vertically from the underlying lamina propria through the olfactory epithelium to the apical surface. This structure represents the duct of an olfactory gland, also known as a Bowman's gland.

Match with options

The highlighted structure corresponds to Bowman's glands (specifically, the duct of a Bowman's gland), which matches option A.

Answer:

• (A) Bowman's glands (Correct answer)
• (B) Nucleus of supporting cell of olfactory epithelium
• (C) Nucleus of olfactory neuron (CN I)
• (D) Insular lobe
• (E) Nucleus of basal cell of olfactory epithelium
