1. Take out your HW
2. Complete the Venn Diagram comparing the
Nervous and Endocrine systems.
Be sure to include 3 examples in each section.
Nervous System
1. Fast response
(reaction time)
2. Uses impulses to
send messages
3. Organs are Brain,
spinal cord, and
nerves
4. Uses Neurons
5. CNS/PNS
Endocrine System
1. Both react to
stimuli
2. Both help
maintain
homeostasis
3. Both are
systems of the
body that send
messages
4. Hypothalamus
is a link
between the
two systems
1. Slower response
(reaction time)
2. Uses hormones to
send messages
3. Organs are called
“glands”
4. Travels through the
bloodstream
5. Hormones:
ex: adrenaline,
thyroxine, HGH,
insulin,
testosterone
Concept Map
HW Answers
1) Autistic people have difficulty communicating
and socializing. Research has shown no
reported brain activity in mirror neuron brain
area.
2) By being able to predict possible outcomes,
locate and determine possible barriers and help
with understanding.
3) Empathy is the ability to understand and share
the feelings of others.
Empathy improves your social skills understanding
how others feel, and helps you to communicate in
ways that make sense to others.

4. Describe how 3 types of neurons work together
If you touch the tip of a needle on a cactus, the
SENSORY NEURONS in your skin will send the
message of “pain” to your INTERNEURONS in
your spinal cord and brain that processes the
message of “pain”. They send the message to
take your hand off the cactus to the MOTOR
NEURONS and they stimulate the muscle in your
hand to move off the needle of the plant.
Cerebrum
Voluntary Tasks:
Thinking, speaking, etc.
Cerebellum
Balance/Coordination
Walk, sports, bicycle, etc
Medulla
Involuntary Tasks:
Heart rate, breathing, etc.
Spinal Cord
Bundle of nerves
that carry messages to
and from the brain
Pituitary (Master Gland)
Thyroid
Parathyroid
Thymus
Adrenal
Pancreas
Testes
Pituitary
Thyroid
HGH: Growth
Thyroxin: Metabolism, calcium/phosphorus
Parathyroid Parathyroid: helps thyroid gland
Thymus
Thymosin: Immune System Support
Adrenal
Adrenaline: “Fight or Flight” response
Pancreas
Insulin/Glucagon: Sugar levels
Testes
Testosterone: Sex Characteristics
When you watch a
scary movie, you may
feel your heart racing,
sweating, breathing
getting heavier etc.
These responses are all caused by the
HORMONE named ADRENALINE.
ADRENALINE is produced by the ADRENAL
GLANDS which sit on top of your kidneys.
This response is called “Fight or Flight”.
*response to a threat: strength or speed*
The nervous system maintains homeostasis in
your body because it constantly processes
information (stimuli) and responds to those
changes in the environment accordingly.
Your nervous system tries to keep you from
harm or hurting yourself.
It also coordinates with the Endocrine system,
since both systems send messages.
