The two important functions of spinal cord are:

(Chapter 3 - The Bases of Human Behaviour)

Here is the list that shows the role of Thyroid gland:

  • This gland is located in the neck. It produces thyroxin that influences the body’s metabolic rate.
  • Optimum amount of thyroxin is secreted and regulated by an anterior pituitary hormone, the Thyroid Stimulating Hormone. (TSH).
  • The steady secretion of this hormone maintains the production of energy, consumption of oxygen and elimination of wastes in body cells.
  • Underproduction of thyroxin leads to physical and psychological lethargy.
  • If thyroid gland is removed in young animals, their growth is stunted and they fail to develop sexually.
