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? UDc UDc

Are All Muscles the Same? Three types: Cardiac, Smooth, and Skeletal Foldable: 1.Tear out a piece of notebook paper 2.Fold “hamburger” style, cut down the fold 3.Cut one paper so that it forms 2 flaps 4.Cut the other paper so that it forms 3 flaps

Foldable Tape or glue the flap on your notebook Label the two flaps Involuntary Muscles Voluntary Muscles 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 Smooth Muscle Tape Skeletal Muscle

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
