Question

Bowman gland are found in
A)Olfactory epithelium
B)External auditory canal
C)Clerical nephrons only
D)Juxtamedullary nephrons.

Answer 1

Hint: Bowman's glands which secrete proteins such as lysozyme, amylase , and IgA similar to the serous glands. It is evident that the bowman's glands do not produce the odorant binding protein.

Complete answer:
Bowman's glands are a type of nasal gland to be found in the olfactory mucosa, underneath the olfactory epithelium, in the lamina propria. It is a connective tissue as well containing fibroblasts, blood vessels and bundles of fine axons as of the olfactory neurons.
An olfactory gland composed of an acinus in the lamina propria and a secretory duct leaving out through the olfactory epithelium.

Electron microscopy studies give you an idea about whether olfactory glands contain cells with large secretory vesicles. Olfactory glands ooze out the gel forming mucin protein MUC5AC.They may secrete proteins for instance lysozyme, amylase and IgA, in the same way to serous glands. The correct composition of the secretions from olfactory glands is unclear, but there is confirmation that they produce odorant-binding protein.
The ultimate elements in the epithelium are Bowman's ducts which expand from the Bowman's glands in the lamina propria to the apical plane where the mucus formed by the glands is discharged. The glands themselves are seen within the lamina propria. The ducts and gland cells split some phenotypic distinctiveness with Sus cells including a common reactivity with several MAbs and high expression of cytochrome P450s.
Bowman's glands are located in the olfactory mucosa, under the olfactory epithelium, in the lamina propria, a connective tissue in addition containing fibroblasts, blood vessels, and bundles of fine axons from the olfactory neurons. The arrangement of the Bowman's glands composed of an acinus in the lamina propria and a secretory duct departing out through the olfactory epithelium.

Hence, the correct answer is option (A)

Note: They are located in the lamina propria of the olfactory membrane. Mucus secreted from these glands will keep the olfactory surface moist.
