A.
Secretion of substances
B.
Contraction of muscles
C.
Transmission of nerve impulses
D.
Storage of minerals
Correct Answer:
Secretion of substances
Explanation:
Glandular epithelium is specialized for producing and releasing substances such as enzymes, mucus, hormones, and sweat.
2. Glandular epithelium is formed mainly by epithelial cells specialized for which activity?
A.
Secretion
B.
Movement
C.
Support
D.
Impulse conduction
Correct Answer:
Secretion
Explanation:
The cells of glandular epithelium are modified to synthesize and secrete useful substances.
3. Which type of gland releases its secretion through a duct?
A.
Exocrine gland
B.
Endocrine gland
C.
Nervous gland
D.
Skeletal gland
Correct Answer:
Exocrine gland
Explanation:
Exocrine glands have ducts through which their secretions reach an epithelial surface or a body cavity.
4. Which type of gland releases hormones directly into the blood?
A.
Endocrine gland
B.
Exocrine gland
C.
Duct gland
D.
Mucous gland
Correct Answer:
Endocrine gland
Explanation:
Endocrine glands are ductless glands that release hormones into the surrounding tissue fluid and blood.
5. Which of the following is an example of a unicellular gland?
A.
Goblet cell
B.
Salivary gland
C.
Thyroid gland
D.
Sweat gland
Correct Answer:
Goblet cell
Explanation:
A goblet cell is a single secretory cell that produces and releases mucus, so it is a unicellular gland.
6. A gland made up of many secretory cells is called a:
A.
Multicellular gland
B.
Unicellular gland
C.
Muscular gland
D.
Nervous gland
Correct Answer:
Multicellular gland
Explanation:
Multicellular glands consist of groups of secretory cells organized into a glandular structure.
7. Which secretion is commonly produced by goblet cells?
A.
Mucus
B.
Bone matrix
C.
Bile pigment
D.
Nerve impulse
Correct Answer:
Mucus
Explanation:
Goblet cells are glandular epithelial cells that secrete mucus, which helps lubricate and protect epithelial surfaces.
8. Which glandular epithelial structure has no ducts?
A.
Endocrine gland
B.
Exocrine gland
C.
Salivary gland
D.
Sweat gland
Correct Answer:
Endocrine gland
Explanation:
Endocrine glands are ductless and release their secretions, mainly hormones, into the blood.
9. Salivary glands are classified as which type of glandular epithelium?
A.
Exocrine glands
B.
Endocrine glands
C.
Unicellular glands
D.
Ductless glands
Correct Answer:
Exocrine glands
Explanation:
Salivary glands release saliva through ducts into the mouth, which makes them exocrine glands.
10. Which of the following is a product that may be secreted by glandular epithelium?
A.
Hormone
B.
Bone
C.
Cartilage
D.
Muscle fibre
Correct Answer:
Hormone
Explanation:
Glandular epithelium can produce hormones, particularly in endocrine glands, as well as substances such as mucus, enzymes, and sweat.
