Weekly Standards: S7L2, S7CS10 Weekly Elements: Explain that
cells are organized into tissues, tissues into organs, organs into
systems, and systems into organisms. Explain that tissues, organs,
and organ systems serve the needs cells have for oxygen, food, and
waste removal. These fall under the categories of metabolism.
Identify that similarities and differences in structures exist
among kingdoms of living organisms Explain that the function of
many systems within an organism involve supporting life by ensuring
the organism maintains homeostasis. build vocabulary knowledge
demonstrate an understanding of conceptual vocabulary in various
subjects use context vocabulary in writing and speaking explore
understanding of new words found in subject area texts
Slide 8
Enduring Understandings 1. Each organ system has structures
(organs) that support each other in carrying out the functions of
that organ system, while collectively working together with other
organ systems to meet the survival needs of the organism. 2. Organ
systems are interdependent. Every action taken by one organ system
has an effect on the rest of the organ systems even though we may
not be aware of what that effect is. 3. There are similar
structures and organ systems in almost all multi-cellular organisms
in the same kingdom that provide similar functions for those
organisms.

Essential Questions Level One What are the major structures of
the nervous system? What are the various functions of the nervous
system? What are the bodys five sense organs? How do nerve impulses
travel to and from the brain? What is the function of a reflex
response and how is a reflex response different from a normal motor
impulse? Level Two 1. How does the nervous system of humans differ
from other organisms in the same phylum? 2. How does the nervous
system work collectively with other systems to help the organism
sustain life?
Slide 10
The brain works like a computer that answers questions and
sends messages (called impulses or signals) all over the body. It
has the appearance of a wrinkled walnut shell. An adult brain
weighs between two and three pounds. It is very fragile and soft
and therefore, needs protection. This protection is provided by the
skull which is a very hard bone. The brain contains long lines of
nerve cells called neurons which function like little telephone
lines that send messages all over the body. Some of these messages
(impulses) go to other parts of the body through the spinal cord.
Messages from the brain move very quickly through the body. The
brain keeps the heart beating and the lungs breathing. It enables
the body to move. It facilitates thinking and remembering. One of
the most important jobs of the brain is to make sure all systems in
the body are functioning the way they are supposed to be and within
certain limits. These limits might include the amount of sugar or
salt in the blood; body temperature; or the amount of water in the
body. This attempt to keep the body operating within normal limits
is known as homeostasis.
Slide 11
The human nervous system consists of the brain, spinal cord,
and peripheral nerves of the body. Central Nervous System- brain
and spinal cord. Peripheral Nervous System- the nerves that extend
into our appendages. The nervous system controls all functions of
the body and allows us to perceive the world through our senses,
process an incredible amount of information, and respond to things
in our world. But it is far more than that. Our brain provides
humans with an ability to think far beyond any other animal.

brachial plexus, a bundle of nerves that extends from the neck
outward through the arm and fingers. Because it is located outside
of the spinal cord, the brachial plexus is a part of the

Slide 18
The brain is connected to the rest of our body by millions of
special nerve cells called neurons. Nerve cells, or neurons, carry
messages to and from the brain at very fast speeds! (Go to How Fast
Are Your Neurons Link on website.) Nerve cells are one-way only.
Each neuron either carries a message to the brain or away from it
depending upon whether they are motor or sensory neurons.

Slide 19
Neurons are similar to other cells in the body in that they
have the full host of organelles: cell membranes, a nucleus (more
than one), mitochondria, cytoplasm, etc. But the shape of neurons
is very different. Neurons have specialized extensions called
dendrites and axons. Dendrites bring information to the cell body
and axons take information away from the cell body. Lets talk
through how a nerve impulse passes along.
Slide 20
Slide 21
Slide 22
Neurons communicate with each other through a series of
lightning fast electrochemical reactions. The axons and dendrites
are separated from other neurons by a small space known as a
synapse. As messages pass from one neuron to another on the way to
or from the brain, the messages are carried across the synapse by
chemicals known as neurotransmitters.
Slide 23
Types of Neurons A. Motor neurons- send messages (impulses)
from the brain to the rest of the body. 1. Voluntary impulses-
messages to our body for movements we control (walking, throwing,
etc) 2. Involuntary impulses- messages to our body for actions we
do not control. Examples of involuntary actions a. Our heart
beating, the muscles of our stomach and intestines contracting
during digestion. b. Blinking and breathing (which is controlled by
an organ called the diaphragm) are examples of involuntary
movements that can also be controlled voluntarily. c. These
different organs function on their own, and are therefore
considered involuntary. These motor messages make up our autonomic
part of our nervous system.
Slide 24
B. Sensory neurons- send messages (impulses) from the senses to
the brain. The sensory organs are 1. Eyes (sight) 2. Nasal passages
(smell) 3. Tongue (taste) 4. Ears (hearing) 5. Skin (touch)

Slide 66
Slide 67
Reflexes are lightning fast commands that fire out from our
brain to help us escape a potentially dangerous or harmful
situation. We jump at a loud sound, quickly pull our hand away from
a hot surface, or instantaneously throw our hands up in front of
our faces when something comes flying toward us. These are all
examples of reflexes. How can our reflexes operate so quickly? Most
sensory impulses (including pain) must be processed by the brain
which then responds in some way to the signal. The motor signals
involved in an impulse response do not get processed in the brain
first. Our nervous system has a way to bypass the brain in
emergencies. Our body is designed to react immediately to potential
danger. Even the fraction of second it might take to think about
the lion jumping out of the tall grass at you might be too long and
result in severe injury or death. Reflex Activity
