Which type of tissue forms glands

  1. Epithelial

  2. Connective

  3. Nervous

  4. Uterus
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Epithelial tissues form the covering of all body surfaces, lines body cavities and hollow organs, and are the major tissue in glands. 

So, the correct answer is 'Epithelial' .

Multiple choice biology windows of knowledge human nose nose nose : the olfactory organ

The glands which help in absorbing odoriferous substances to stimulate olfactory nerve are

  1. Cerumenous glands

  2. Meibomian glands

  3. Bowman's glands

  4. Cowper's glands

  5. Bidder's glands
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Bowman's glands are branched tubular glands in the olfactory mucous membrane. The structure of the Bowman's glands consists of an acinus in the lamina propria and a secretory duct going out through the olfactory epithelium. Bowman's glands secrete proteins, such as lysozyme, amylase and IgA similar to serous glands. 

Multiple choice biology windows of knowledge human nose nose nose : the olfactory organ

Glands whose secretions pick up odoriferous substances to stimulate olfactory nerves are

  1. Bidder's glands

  2. Cowper's glands

  3. Meibomian glands

  4. Bowman's glands

  5. Ceruminous glands
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Bowman's glands are olfactory glands present in olfactory mucosa below olfactory epithelium. They contain secretory vesicles. They secrete mucous substances that prevent the nasal epithelium from getting dry out. The secretions from these glands pick up odoriferous substances i.e. the substances that have a particular smell, and stimulate olfactory nerves which carry the information related to smell to the brain.
So, the correct answer is 'Bowman's glands'.
Multiple choice biology tissues, organs, organ system, organism tissues of animals animal tissues and its type tissues: animal tissues fluid connective tissue

  1. Epithelial tissue

  2. Connective tissue

  3. Skeletal tissue

  4. Muscular tissue
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Mammary glands are a modification of the epithelial layer or epithelial tissue. They are formed of the glandular epithelium.

So, the correct option is 'Epithelial tissue'.
