Why are hormones important?

Answer 1

Hormones transmit signals from a group of cells to a group of another cells, where its effect is determined to the pattern of secretion and the response of the receiving tissue. It has a long onset of action than neurons and thus is more suitable for controlling slow processes of the body, e.g. growth, menstural cycle, metabolism regulation

Answer 2

Hormones are chemical messengers in the body which control certain processes in the body, such as reproduction and homeostasis.

For example, insulin is a hormone in homeostasis which controls the concentration of glucose in the blood by causing its conversion into a insoluable substance. Without it (as in Type 1 Diabetes), the blood sugar level would rise uncontrollably.

Answer 3

Sex hormones (androgens, estrogens, and progestins) are important for:

- growth

- reproductive function

- maintenance of sex drive

- ability to build muscle tissue or breast tissue

Corticosteroids are important for:

- maintenance of proper water balance and kidney function

- proper immune function

- antiinflammatory activity

All of these steroid functions are carefully balanced by various feedback systems in the body.

When estrogens or progestins are taken by women, they help with hormone deficiencies as well as Birth Control.

When androgen steroids are taken by men, they can temporary help with muscle gain, but only at a cost (since it unnaturally increases the body's androgen levels, which causes the body to become more tolerant to its own androgens, and this leads to problems later).

When corticosteroids are taken, they can help with inflammation and allergic reactions. However, over time, it will compromise the body's immune system and can also lead to psychotic reactions.
