Question

Which of the following is incorrect about the pancreas gland?
  1. It acts both as an exocrine and an endocrine gland.
  2. The endocrine pancreas consists of 1-2 million ‘Islets of Langerhans’.
  3. It produces the hormones insulin and glucagon.
  4. It is located above the kidney.


Solution

The correct option is D It is located above the kidney.
The pancreas is located below the stomach. The adrenal gland is located above the kidney.

The pancreas is a mixed gland. It acts both as an exocrine and an endocrine gland.

The endocrine pancreas is composed of 1-2 millions of ‘islets of Langerhans’. These are island-like tissues interspersed between the exocrine tissues of the pancreas.

There are two main types of cells in the islet of Langerhans, α-cells and β-cells. The α-cells secrete a hormone called glucagon, while the β-cells secrete insulin.
