Functions
These attach muscles to bones.
Tendons
The definition of a JOINT.
Where two bones come together.
This muscle is involved in raising your lower arm.
Biceps
This muscle is involved in lowering your lower arm.
Triceps
One way the skeletal system interacts with the respiratory system.
Ribcage protects the lungs.
This smooth, white substance is found at the end of bones and prevents the bones from rubbing against each other.
Cartilage
Definition of SKELETAL MUSCLES.
Muscles that are attached to bones.
These attach your upper arm muscle to your lower arm bone.
Tendons
The muscle that lowers your lower arm is attached to this lower arm bone.
Ulna
One way the muscular system interacts with the circulatory system.
The heart is made of cardiac muscle that contracts to pump blood.
These attach bones to other bones.
Ligaments
These 26 bones make up your spine.
Vertebrae.
The muscle that raises your lower arm is attached to this upper arm bone.
Humerus
This process of your upper arm muscle needs to happen to lower your arm.
Contraction
One way the muscular system interacts with the respiratory system.
The diaphragm contracts and relaxes to allow you to inhale and exhale.
This syrup-like substance prevents bones from rubbing against each other and also helps them move smoothly.
Synovial Fluid
The three bones of your arm (of a chicken's wing, too).
Humerus, Radius, Ulna
The muscle that raises you lower arm is attached to this lower arm bone.
Radius
This is happening to your biceps when your arm is lowered.
Relaxes
One way the muscular system interacts with the digestive system.
Smooth muscle surrounds digestive organs and contracts to move food/waste along. This is peristalsis.
These are the first two cervical vertebrae (not on the quiz).
Atlas and Axis
This bone is located directly over your heart.
Sternum
Explain how your lower arm is raised.
Your biceps contracts and pulls on the tendon which pulls on the radius and raises your arm.
Explain how your lower arm is lowered.
Your triceps contracts and pulls on the tendon which pulls on the ulna and lowers your arm.
One way the skeletal system interacts with the circulatory system (other than protecting the heart).
Blood cells are produced in the bone marrow.
