Vocabulary
 600 Muscles
 Muscular system –Group of
structures that make up
your large muscle groups.
 Skeleton – Muscle attached
to bone.
 Smooth – Found in organs
and blood vessels and
glands.
 Cardiac – Found only in the
walls of the heart.
Characteristics of Muscles
 Muscle cells are elongated
(muscle cell = muscle fiber)
 Contraction of muscles is due to the movement of
microfilaments
 All muscles share some terminology
 Prefix myo refers to muscle
 Prefix mys refers to muscle
 Prefix sarco refers to flesh
10-2
 What is the compare and contrast between smooth
muscle, and Skeleton muscle.
 Make a vein diagram
Function of Muscles




Produce movement
Maintain posture
Stabilize joints
Generate heat
Muscle Movement
 You have muscle to move your body around.
 There is muscles that you do not control like your
heart, and intestine.
 What then tells these muscles to move?
 Type of Muscle Movement
 Involuntary- Automatically move without you knowing.
 Voluntary- Brain sends message to muscle. You control the
movements.
Muscles work
 Muscle stimulated by nerves and work by contracting
and relaxing.
 Muscle work in pairs, with one muscle contracting
other is shorting.
 This helps stabilize the joint and have a smooth
movement.
Talk to your Neighbor




Discuss with your neighbor the following:
Function of muscle
Muscle movement
How the muscle work
 Your choice, but you will have to discuss with the
class.
Smooth muscle!
 Smooth – Is found in
the organs, with the
blood vessels, and
glands. They work
on an involuntary
action. You do not
need to think for it
to happen. Where is
smooth muscle
found in the human
body?
Skeletal muscles
 Muscle that attached to
bone that enables you to
move your body. There is
over 20 major muscle in
your body.
 If we did not have muscle
what would we look like
and how would we move?
 Do “Skeletal muscle and
working pairs ” in human
workbook. Page 12
 Picture is from Google.com
Cardiac muscle
 This is involuntary , this
is only found in your
heart. It moves blood
out through the body.
This is how your
oxygen and nutrition
are moved to cell of
your body.
 Picture is from Google.com
In the human workbook
 Do the following: “Your muscles” page 10“ and
Muscle Man” page 11 This is a review of the three
different types of muscle cells!
Heart is made of four chambers
 The heart makes
up the one piece of
the circulatory system.
Picture is from
Google.com
Four chambers are
 Right and left Atrium
 Right and left Ventricle.
~In between the Atriums and
Ventricle there are valves.
~ These valves open up and
blood moves between the
Ventricles and Atriums.
~ Atriums always feed the
Ventricles.
~ The heart flows in one
direction, so it is called
a one way flow.

Think pair share
 With your partner or group! Discuss the following
questions.
 What are the two types of chambers of the heart?
What is a way to remember the chambers?
Problems with the muscular system
 Pulled or torn muscle – Torn away from the bone or
has been damaged within itself.
 Muscle strain – type of soreness that develops in a
muscle that is overused.
 Muscle cramp – remains contracted rather then
relaxed.
 Muscle dystrophy – disorder that is unusually
inherited . It weakens skeleton muscle.
Care for the Muscular system!
 Physical activity – More you use your muscle the
stronger they become.
 Warm – up – Before exercise and have cool down.
 Eat foods balanced in vitamins, minerals,
proteins, and carbohydrates.

review of the notes you have taken.
Review your answers on
“MUSCLE MAN”
W.I.L.T.

your paper. Explain how the muscle system
needs the other body systems that we have
covered.
 First paragraph – what is the muscle system.
 Second paragraph- Describe the different muscles in the
system. Type of muscles
 Third paragraph – What is the job of these muscle
 In conclusion, the muscle system needs the nervous
