Question

Bowman's glands are located in the
A. Proximal end of uriniferous tubules
B. Anterior pituitary
C. Female reproductive system of cockroach
D. Olfactory mucosa of our nose

Answer 1

Bowman's glands are also known as olfactory glands. The term olfactory is something which is related to smell. The receptors associated with smell are called olfactory receptors and are present in the nose. Let us see the structure of the nose to understand where the bowman's glands are present.

Complete answer:
It is clear that Bowman's gland is located in the nose. Let us understand its detailed structure.
Nose is the structure meant for respiration and they contain olfactory organs. It has two cavities separated by a cartilage.The external openings are called nostrils which have a vestibule above it. There are three elevations present behind the vestibule which are called concha. Olfactory region is present beside and above the concha and the rest of it is the respiratory region. This region has a mucous membrane which contains cilia. Thu mucus secreted by it helps in trapping dust particles and keeps it moist. Within the nasal cavity, olfactory epithelium is present which contains ciliary extensions which trap the odour molecules. Here comes the Bowman's gland. It is present in the olfactory mucosa beneath the olfactory epithelium. These are branched alveolar glands and secretes mucus to keep the epithelium moist.

By the above explanation,the correct option is D.

Note:
Bowman's capsule is often confused with Bowman's gland. The outer part of the kidney in the cortex region contains Bowman's capsule which is a double walled structure and is a part of the nephron whereas Bowman's gland is the structure related to the nose which can detect the smell of the compounds inhaled through air.
