The endocrine system
is a complex network of chemical signals and messages
that control many immediate and life-long bodily
responses and functions:
Growing taller, developing
male or female characteristics and reacting to fear
are all partially directed by endocrine hormones.
All animals with backbones - from fish to mammals
- have an endocrine system that works hand-in-hand
with the nervous system to:
• maintain the body's internal
steady state
(nutrition, metabolism, excretion, water and salt
balance);
• react to stimuli from outside the body;
• regulate growth, development and reproduction;
and
• produce, use and store energy.
-
relay information and instructions throughout the
body. Sometimes the whole process works within seconds,
say, in response to fear. Other times it reacts
more slowly, telling body parts when and how much
to grow and developing characteristics that distinguish
male from female.
It happens like this:
1. Glands and nerve cells signal endocrine
glands about temperature changes, hunger, fear,
growth needs or other stimuli.
2. In response, endocrine glands release
hormones to carry instructions to specific cells.
These chemical messengers travel from head to toe
or just to the cell next door looking for and locking
onto special binding proteins, known as receptors,
that are located in and on the target cells.
3. Once bound, the receptor reads
the hormone's message and carries out its instructions
by starting one of two distinct cellular processes.
The receptor can:
A. turn on genes to make new proteins, which causes
long-term effects such as:
Growth - growth hormones
control height and bone structure, too little causes
dwarfism, too much causes giantism (acromegaly).
Sexual and reproductive maturity
- sex steroid hormones help develop, regulate and
maintain male and female sex characteristics (breast
size, bone density, muscle development, sperm production),
cycles (uterine growth, pregnancy) and behavior.
B. Alter the activity of existing
cellular proteins, which produce rapid responses
such as:
A faster heart beat -
releasing stored adrenalin in response to being
frightened or nervous causes the heart to race.
Varied blood sugar levels
- the hormone insulin regulates blood sugar
by modifying glucose uptake by many tissues (low
insulin levels leads to diabetes).

**If you are on
Thyroid medication check with your doctor
after being on maca for a few months. It
has been know to stimulate the thyroid to
