maintaining homeostasis?
Conclusion Questions
1. Describe the function of the endocrine
system.
• Regulates
all life process
2. Describe hormones and how they are
transported throughout the body.
• Hormones are
special PROTEINS,
which act as
signals.
• Hormones are
transported in
the
BLOOD.
3. Identify the cells affected by hormones and
the structure that hormones attach to on those
cells.
• Hormones affect
TARGET CELLS.
• Hormones attach
to RECEPTORS
on the target cells.
1. Identify
structure B.
Support
your answer.
2. Explain why
cell C is the
target cell.
4. Compare and contrast the nervous and
endocrine system.
• They BOTH regulate the body.
• They BOTH send messages to different parts of
the body.
• The endocrine system releases HORMONES.
The nervous system transmit IMPULSES.
• Endocrine system messages are chemical.
Nervous system messages are electrical and
chemical.
• The endocrine system is made up of endocrine
glands. The nervous system is made up of the
brain, spinal cord and nerves.

growth hormone.

Verne Troyer, 30,
describes himself as a
"little person or dwarf,"
is 2 feet, 8 inches tall.
14-year old
Khagendra Thapa
Magar shown in the
picture with another
boy is only 50cm (20
inches) tall and has
been submitted to the
Guinness world record
as the world's
smallest person. The
previous world record
holder was a
Jordanian boy at 25.5
inches tall. Weighing
only 4.5 kilograms, he
is shown in exhibitions
to collect fund for his
education.
Robert Pershing Wadlow is the
tallest person in medical history.
He is often known as the "Alton
Giant" because of his Alton,
Illinois hometown. Robert
Wadlow reached 8 feet 11.1
inches in height and weighed
490 pounds at his death. His
great size and his continued
growth in adulthood was due to
an abnormally high level of
human growth hormone. He
showed no indication of an end
to his growth even at the time of
his death.
Robert Wadlow's size began
to take its toll: he required
leg braces to walk, and had
little feeling in his legs and
feet. Despite these
encounters, Robert Wadlow
was never confined to a
wheelchair.
On July 4, 1940, a faulty
brace irritated his ankle,
causing a blister followed by
an infection. Doctors treated
him with a blood transfusion
and emergency surgery, but
his condition worsened and
on July 15, 1940, he died in
his sleep. He was 22.

This X-ray shows
how an enlarged
right lobe of the
thyroid has moved
the trachea to the

4. control and coordinate system
interactions
A student accidentally places
her hand on a tack and
quickly pulls her hand away.
The tack represent
1. a stimulus
2. an impulse
3. a response
4. an effector
In a simple spinal reflex, the
pathway for an impulse is along a
sensory neuron directly to a
motor neuron through
(1.) a receptor
(2.) an interneuron
(3.) an effector
(4.) the brain
A change that initiates an
electrochemical message along a
neuron is known as
1. a stimulus
2. a response
3. an impulse
4. a synapse

hearing a clap of thunder, the clap of
thunder would serve the nervous
system role of acting as a(n)

acid to the water surrounding a
hydra caused the hydra to contract.
