Objective: SWBAT explain

how the body moves

WARM UP:

1. Write the definition of the muscular system in your notebook. (Look up the definition in the back of the yellow textbook)

Moving the Body

Muscular System

• The muscles of the body that, together with the skeletal system, functions to produce movement

• Gives us strength

Remind me…

• What is the function of the SKELETAL SYSTEM?

• What do we call the place where two or more bones meet?

Joints

• Immovable (fixed) joints: joint that does not move

Example: joints in between the bones of your skull

• Movable Joints: joints that move Example: finger joints

Movement• Can your bones move on their own?

Connective Tissues• Tendons: connect MUSCLES to BONES• Ligaments: Connect BONES to BONES

• Cartilage: Strong and flexible connective tissue that covers the ends of bones at a joint. It also gives shape and support to other parts of the body, like ears, nose and the windpipe.

Supporting the Support System!

• What is the function of the MUSCULAR SYSTEM?

• What different types of muscles?

Are All Muscles the Same?

• Three types: Cardiac, Smooth, and Skeletal

Foldable:1. Tear out a piece of notebook paper2. Fold “hamburger” style, cut down the fold3. Cut one paper so that it forms 2 flaps4. Cut the other paper so that it forms 3 flaps

Foldable

• Tape or glue the flap on your notebook• Label the two flaps

InvoluntaryMuscles

VoluntaryMuscles

Tape

Muscle Notes!

• Muscles are divided into two main categories

Involuntary: Muscles that can contract without you actively making them

Example: pupils in your eye

Muscle Notes!

• Voluntary: muscles that contract when you make them do so

Example: skeletal muscles

Foldable• Tape or glue the other flap on your page or

back of page• Label the three flaps

Cardiac Muscle

SmoothMuscle

Tape

SkeletalMuscle

Three types of Muscles

• Cardiac Muscle: -found only in the heart-makes the heart beat

• Would this be a voluntary or involuntary muscle????

Three types of Muscles

• Smooth Muscle: -not banded, it’s smooth-inside many organs like the stomach-mostly involuntary

Three types of Muscles

• Skeletal Muscle: - “striated” or banded-attaches to bones-moves bones

• Would this be a voluntary or involuntary muscle????

Add Drawings

• Page B 24 and B 25 in big yellow textbook

• DRAW cardiac, smooth, and skeletal muscle next to the definitions in your foldable
