The Endocrine System
HORMONES ACT ON SPECIFIC
CELLS
Amino - Acid Based
Hormones – are water-soluble
hormone made of amino acids.
Steroid Hormones – fatsoluble hormone derived
cholesterol.
Once hormones are secreted
into the blood or extracellular
fluid they are transported to a
target cell(s) where they will
have a desired effect.

Actions of Hormones
The Endocrine System
HORMONES ACT ON SPECIFIC CELLS
Protein based
hormones bind to
a specific
receptor on the
cell membrane of
the target cell.
The Endocrine System
HORMONES ACT ON SPECIFIC CELLS
This binding of the
hormone and membrane
receptor causes a series
of internal changes to
occur with in the target
cell.
The Endocrine System
HORMONES ACT ON SPECIFIC CELLS
Examples of
changes include
transcription,
exocytosis or
endocytosis,
membrane channels
to open or close.

The Endocrine System
HORMONES ACT ON SPECIFIC CELLS
Steroid
hormones are all
derived from
cholesterol, a
lipid. It can
diffuse directly
through the cell
membrane, which
is also made up
of lipids.
The Endocrine System
HORMONES ACT ON SPECIFIC CELLS
Steroid
hormones
usually combine
with nuclear
membrane
receptors. This
produces an
activated
hormonereceptor
The Endocrine System
HORMONES ACT ON SPECIFIC CELLS
The receptor
hormone complex
will bind directly
to a gene and
causing
transcription of
the gene to occur,
leading to the
production of a
new protein.

THE RELEASE OF HORMONES MUST BE REGULATED
Negative Feedback – mechanism
used in homeostasis to keep
monitored variable within a
certain range. A change in one
direction stimulates two control
mechanisms to counteract further
change in the same direction.
Homeostasis is one of the fundamental characteristics of living
things. It refers to the maintenance of the internal
environment within tolerable limits. All sorts of factors affect
the suitability of our body fluids to sustain life; these include
properties like temperature, salinity, acidity, and the
concentrations of nutrients and wastes. Because these
properties affect the chemical reactions that keep us alive, we
have built-in physiological mechanisms to maintain them at
desirable levels.
When a change occurs in the body, there are two general
ways that the body can respond. In negative feedback, the
body responds in such a way as to reverse the direction of
change. Because this tends to keep things constant, it allows
us to maintain homeostasis. On the other hand, positive
feedback is also possible. This means that if a change occurs
in some variable, the response is to change that variable even
more in the same direction. This has a de-stabilizing effect, so
it does not result in homeostasis. Positive feedback is used in
certain situations where rapid change is desirable.
To illustrate the components involved in negative feedback,
we can use the example of a driver trying to stay near the
speed limit. The desired value of a variable is called the set
point. Here, the set point is a speed of 55 mph; in controlling
body temperature, the set point would be 98.6 degrees. The
control center is what monitors the variable and compares it
with the set point. Here, the control center is the driver; for
body temperature, it would be the hypothalamus of the brain.
If the variable differs from the set point, the control center
uses effectors to reverse the change. Here, the effector is the

Liver, muscle
Decreases blood sugar, decreases blood
pressure, decreases heart rate in response
to no stress – rest and digest
Kindey, sweat glands

increases blood pressure; stimulates kidneys
to get rid of potassium
