Skeletal and Muscular Systems

What is the Skeletal System?

​

It includes bones, cartilage, and ligaments.

It also gives your body its form and protects your organs.

Cartilage, Ligaments & Tendons

• What is cartilage? It is a spongy connective tissue that cushions the ends of many bones.

• How are the bones at the joint held together? Ligaments

• How are muscles attached to the bones? Tendons

Multiple Choice

• at tissues

Multiple Choice

Which is NOT a function of the skeleton?

• providing a framework for soft tissues

• excreting waste from the body

• protecting inner organs

• helping you move around

What is the muscular system?

It includes muscles and tendons that connect muscle to bones. It allows you to move.

Skeletal Muscle

• Support and move the body

• voluntary muscles - you control them.

• Ex: Leg muscles

Involuntary Muscles

(You Can't Control Them)

• smooth muscle - makes up most of the walls of the body’s organs,

  including blood vessels and digestive organs.

• cardiac muscle - makes up the walls of the heart.

Multiple Choice

How do your voluntary muscles know when to function?

• through changes in body temperature

• when they start cramping

• your brain sends impulses through a motor neuron

• they are automatic

Multiple Choice

What is an example of a voluntary muscle?

• smooth muscle

• cardiac muscle

• skeletal muscle

Multiple Choice

What are the muscles that make up the heart?

• smooth muscles

• cardiac muscles

• skeletal muscles

How do opposing muscles cause movement at a joint?

First, one muscle contracts causing the joint to bend then the other muscle contracts,

causing it to straighten

Multiple Choice

What is the padding between bones?

• ligaments

• tissue

• cartilage

• tendons
