Which of the following is/are NOT an endocrine gland in our body?

•  Thyroid gland :
  The thyroid gland is an endocrine gland. It secretes hormones like thyroxine (T4) and triiodothyronine (T3) that regulate metabolism, growth, and development.

•  Pituitary gland :
  The pituitary gland is the master endocrine gland. It secretes various hormones that regulate other endocrine glands. Some of the hormones it releases include growth hormone (GH), prolactin, and thyroid-stimulating hormone (TSH).

•  Adrenal gland :
  The adrenal glands are endocrine glands located above the kidneys. They secrete hormones like adrenaline (epinephrine), noradrenaline (norepinephrine), and cortisol. These hormones play key roles in the body’s stress response and metabolism.

•  Salivary glands :
  The salivary glands are exocrine glands, not endocrine. They secrete saliva into the mouth through ducts. Saliva contains enzymes like amylase that aid in digestion. Unlike endocrine glands, they do not secrete hormones directly into the bloodstream.

Summary:

• Endocrine glands: Thyroid, Pituitary, Adrenal
• Exocrine gland: Salivary glands
