The Nervous System
The Endocrine System
The Brain
We inherit traits from our parents through
genes
Genes are made up of units of DNA that are
our genetic makeup
They are assembled into Chromosomes: we
have 46 (23 from each parent)
All behavior can not be linked to genetics but
some things can be like genetic disorders
Ex: Down Syndrome is caused by a fragment in
the 21st chromosome
On your own, read “Choosing your Children’s
Genes” on pg. 46.
After reading, answer the 4 questions in your
packet.
1. There are two types of ways your body
communicates internally. They are…
- Through the nervous system
-Through the endocrine system
2. The nervous system usually generates your first,
quick response.
3. Your endocrine system is run by your hormones
which act as transmitters to the brain.
Network of neurons
Neurons – cells that specialize in receiving
and transmitting information through the
body
Split into Central and Peripheral Nervous
System
The Nervous System

Neurons and how they work:

Made up of the brain and the spinal cord
Connects the Central nervous system to the
rest of the body
Split into Autonomic and Somatic Nervous
Systems
Part of Peripheral Nervous System
Sends messages to internal organs
Coordinates functions of internal organs
Ex: respiration or digestion
Part of Peripheral Nervous System
Send messages to body’s muscles
This is what allows you to text
Biochemical substances that stimulate or
suppress other neurons
Imbalances can cause major disorders
Ex: Dopamine, Serotonin
Fill out the chart using the placards
Endocrine glands release hormones into the
bloodstream where they affect a wide array
of bodily functions and behaviors
They coordinate with the nervous system
Hypothalamus- part of the brain that directs
activity in the endocrine system.
Pituitary gland (master gland) – receive
messages from the hypothalamus to
stimulate or inhibit the release of other
glands hormones
Endocrine System and the Pituitary gland
Brain Pop
Using pg. 57 in the text
Thyroid Issues:
Underactive – lack of energy, weight gain, dry skin or hair
Overactive- Increased nervousness, rapid heart beat,
weightloss
Pancreas Issues:
Type 2 Diabetes
Pancreatitis
▪ Flu-like symptoms, Weight decrease, rapid pulse
Involved in complex mental processes
Separated into 4 lobes
Regulates coordinated movements
Sets brains alertness level and warning
system
Pathway for neurons traveling to and from
the brain
Manages body internal state
Regulate motor movement and cognitive
abilities like planning and decision making
Personality
Motor Cortex- controls the body’s voluntary
muscles
Motor speech area (Broca’s area)
Process sensory information like touch,
temperature, body position and pain
Right half communicates with the left side of
the body – Left half communicates with the
right side of the body
Processes Sounds
Stores long term memories
Processes vision and
sensations from the
eyes
Color, movement,
shape, shading, and
face recognition

AREAS OF LEFT-HEMISPHERE
DOMINANCE:
Verbal functions (for
right-handers and most
left-handers), including
spoken and written use of
language, as well as
logical analysis, problem
solving, and
mathematical
computation
AREAS OF RIGHT-HEMISPHERE
DOMINANCE:
Nonverbal functions,
including understanding
spatial relationships (as
presented, e.g., in jigsaw
puzzles or maps),
recognizing faces and
interpreting gestures,
perceiving and expressing
emotion, and
appreciating music and
art
1 volunteer
Students should separate into pairs and
choose one person to be the observer.
Involved left hemisphere functions (verbal,
math, analytic)
Trend- eye movements to the right when
processing the question
Involved right hemisphere functions
(nonverbal, spatial, holistic)
Trend – eye movement to the left from
processing
