Task: Class Definition Understanding (ontology: Sciences/Biology)

Which of the following definitions best describes 'salivary gland glandular cell'?

A. Glandular cell of salivary gland. Example: Serous cells, mucous cells, cuboidal epithelial cells of the intercalated ducts, simple cuboidal epithelium of the striated ducts, epithelial cells of excretory ducts.
B. This cell type produces and secretes melatonin and forms the pineal parenchyma. Extending from each cell body, which has a spherical, oval or lobulated mucleus, are one or more tortuous basophilic processes, containing parallel microtubules known as synaptic ribbons. These processes end in expanded terminal buds near capillaries or less, frequently, ependymal cells of the pineal recess. The terminal buds contain granular endoplasmic reticulum, mitochondria and electron-dense cored vesicles, which store monoamines and polypeptide hormones, release of which appears to require sympathetic innervation.
C. Hormone secreting cell located in the cortex of adrenal gland. Glandular cells in the adrenal cortex secrete mineralocorticoids, glucocorticoids and androgens.
D. A(n) serous secreting cell that is part of a(n) bronchus submucosal gland.

Answer: Glandular cell of salivary gland. Example: Serous cells, mucous cells, cuboidal epithelial cells of the intercalated ducts, simple cuboidal epithelium of the striated ducts, epithelial cells of excretory ducts.
