Hormonal Coordination in Animals Homework Help

Hormones are defined as chemical compounds secreted by specialized cells or glands which are helpful in transmitting information to different locations. It is also helpful in the wider distribution of information in animals. Hormones constitute an alternate way of coordination in animals besides electrical impulse transmission of information using nerve cells.

Growth regulation by hormones

Hormones secreted by various glands like endocrine glands (Fig 1) in our body helps in regulating growth by performing certain specific functions e.g. adrenaline, thyroxin, growth hormone, insulin, Testosterone, and estrogen. Secretion of these hormones should be in an accurate quantity and very precise as minor changes in their level in the body may result in serious effects.

Endocrine glands in female and male


This hormone is secreted by the adrenal gland and is released in stress situations like fear, pain, anxiety etc. It generally acts on the heart. The response of this hormone includes faster heartbeat, increased breathing rate and contraction of muscles around digestive system, skin, diaphragm and rib muscles.


This hormone is secreted by the thyroid gland and helps the body to get a balanced diet for proper growth. Thyroxin plays a major role in metabolizing protein, fats etc. Iodine plays a major role in the secretion of thyroxin. This is the reason why iodized salt is advised in the diet. Deficiency of iodine leads to goiter disease with symptoms of the swollen neck.

Growth hormone

This hormone helps in proper and balanced growth and development of the body. Deficiency of this hormone in childhood may lead to dwarfism.
