Which one of the following is a salivary gland?

  • A.Parotid gland
  • B.Adrenal gland
  • C.Thyroid gland
  • D.Parathyroid gland

Answer: A

The salivary gland is the parotid gland.

The parotid is the largest salivary gland in most domestic animals, lying below the ear, and opens into the mouth by the parotid duct opposite the upper cheek teeth. With the mandibular and sublingual glands it produces saliva, which in ruminants buffers the rumen.

The adrenal, thyroid and parathyroid glands are endocrine glands: they have no ducts and release hormones into the blood, not saliva into the mouth.
