Warm UpStudy for Skeletal System Quiz
(SILENTLY)
5 Functions of the Skeletal System
Types of Joints (how they move, where they are)
Layers of Bone
Axial Skeleton
Appendicular Skeleton
Quiz12 Minutes to complete
When finished, read silently
Muscular System
Muscular SystemYou have over 600 muscles in your body!
VocabularyMuscle: An organ made of muscle tissue, which moves
a particular bone, part, or substance of the body
Contract: to make smaller, decrease. When you flex a muscle you are contracting it.
Expand: to make larger, increase. When you relax a muscle you are expanding it
Homeostasis: a condition needed for good health in which an organisms keeps a relatively stable internal environment
Peristalsis: the wavelike contraction of stomach muscles which help to churn up food
Muscular System Functions
1. Movement
2. Maintaining Body Temperature
3. Posture
Movement Muscles are connected to
bones by tendons
Muscles provide the pull that bones need to move
Muscles contract, cause movement at joints
Maintaining Body Temperature
Normal Human Body temp = 98.6F
It stays this way because of your muscles
- *When muscles contract, they release heat
- Shiver = quick muscle
contractions to warm you up
PostureMuscle constantly
contract and relax or make small changes to hold you up right
The muscles of the body also make joints strong
3 Types of Muscles1.Skeletal Muscle
Attached to your bones
2. Smooth MusclesInside some organs like the stomach
3. Cardiac MuscleYour heart
Types of MusclesVoluntary: Controlled directly by your thoughts
Skeletal Muscle: muscle attached to bones by tendons
Involuntary: Move without you thinking about itSmooth Muscle: muscles of internal organs (stomach)Cardiac Muscle: muscle that makes up your heart

Muscular System PacketBegin Work to Complete Packet
How do muscles grow?27B
Exit Ticket – no notes1. Your stomach is made of
a) Cardiac Muscleb) Skeletal Musclec) Smooth Muscled) Voluntary Muscle
2. Which is not a function of the muscular system?a) Postureb) Movementc) Protectiond) Maintaining Body Temperature.
3. What is the difference between Voluntary and Involuntary Muscle?
Warm Up*Put last night’s homework on desk to be graded
(39 and 40 of packet)
Answer on notebook paper to turn in. You do not have to write questions.
Why do you think it is important that the heart is an involuntary muscle?
2. Why do you think it is important that the muscles in our legs are voluntary muscles?
Yesterday’s Exit1. Your stomach is made of
a) Cardiac Muscleb) Skeletal Musclec) Smooth Muscled) Voluntary Muscle
2. Which is not a function of the muscular system?a) Postureb) Movementc) Protectiond) Maintaining Body Temperature.
3. What is the difference between Voluntary and Involuntary Muscle?
Voluntary = you control and decide when it moves
Involuntary = Automatic, your body does it without you telling it to

Muscles of DigestionChewing Food = Voluntary
Swallowing Food = Voluntary
Food Traveling Through Intestines = Involuntary
Peristalsis = Involuntary
So is digestion voluntary, involuntary or both?
BOTH
Today’s Agenda1. Finish Packet Started Yesterday
2. Read 27B in textbook. Explain why exercise helps muscles get bigger.
3. Complete Types of Muscle Charts (use 25B for help)
4. “How Many Muscles Does it Take to Smile?” Article
5. “Your Bones and Muscles” Article
Exit1. The muscular system is made of both Voluntary and
Involuntary muscles, which type aid in digestion?
A. Both
B. Neither
C. Voluntary
D. Involuntary
2. When you are cold, your body shivers. Explain how this is an example of a function of the Muscular System.
Warm Up – put packet on desk
1. Where in your body do you have cardiac muscles?
2. True or False – shivering is an example of your muscles performing one of their main functions
3. Why are skeletal muscles considered voluntary muscles?
Warm Up Review1. Where in your body do you have cardiac muscles?
Heart. The word cardiac means heart!
2. True or False – shivering is an example of your muscles performing one of their main functions
True. One function of the muscular system is maintaining body temperature. When you’re cold your body shivers to try to warm you up
3. Why are skeletal muscles considered voluntary muscles?
They are considered voluntary because you must tell them to move, they do not move automatically
Quiz Return
1. Blood Cells
2. Protect, Skull, ribs and spine
3. Outside layer
4. Protection, movement, support, mineral storage, blood cell production
5. Protect = keep insides safe
Movement = help body move
Support = hold you up
Blood cell production = bone marrow makes blood
Mineral storage = calcium is stored in bones
6. Ball and Socket
7. Immovable, Skull
8. Both are made of bones but axial protects and Appendicular helps you move
9. Sliding or gliding
10. Ball and socket
Packet ReviewCorrect wrong answers!
3 functions of muscular system
1. Movement
2. Maintaining Body Temperature
3. Posture
