1. Take out your HW
Complete the Venn Diagram comparing the
Nervous and Endocrine systems.
Be sure to include 3 examples in each section.

2. Nervous System Endocrine System
Fast response (reaction time)
Uses impulses to
send messages
Organs are Brain,
spinal cord, and
nerves
Uses Neurons
CNS/PNS
Both react to stimuli
Both help maintain homeostasis
Both are systems of the body that send messages
Hypothalamus is a link between the two systems
Slower response (reaction time)
Uses hormones to send messages
Organs are called “glands”
Travels through the bloodstream
Hormones:
ex: adrenaline, thyroxine, HGH, insulin, testosterone

3. Concept Map

4. HW Answers
Autistic people have difficulty communicating and socializing. Research has shown no reported brain activity in mirror neuron brain area.
By being able to predict possible outcomes, locate and determine possible barriers and help with understanding.
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.

10. 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.

11. 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

12. Pituitary (Master Gland)
Thyroid
Parathyroid
Thymus
Adrenal
Pancreas
Testes

13. Pituitary HGH: Growth
Thyroid 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

14. 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*

15. 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.
