Skeletal System
system responsible for providing shape and support for the body,
protection for internal organs, and production of blood cells
Function of Bones
provide support and shape, provide place for attachment of muscle, and to
produce blood cells
Cartilage
soft, flexible tissue found at the ends of bones, ears, nose and other areas of the
body.
Ligaments
a band of tissue that connect bone to bone
Tendon
connect bones to muscles
Bone
made of minerals such as calcium, they move when skeletal muscle attached to them contract or get shorter, and, larger ones produce
blood cells in the marrow
Joints
a place where two or more bones meet
Ball and Socket Joint
very mobile, the end of one bone is shaped like a ball, the end of the other bone is shaped like a cup, the “ball” sits in
the “cup” and is able to rotate.
Examples include the hip and the shoulder
Hinge Joint
one bone moves like a door swinging on its hinges.
Examples: elbow and the knee
Pivot Joint
a bone rotates or “pivots” around another; we have pivot joints in our arms, and at the base of our skull
Gliding Joint
bones “glide” past each other; we have them in our wrists and feet
Muscular System
the system responsible for providing movement in our body. Movement occurs by the muscles
getting shorter (contracting) and relaxing
Skeletal Muscles
muscles that make our bones move, they make our bones move by getting contracting and pulling on the bones. These
muscles are voluntary.
Cardiac Muscles
muscle found in the heart, These muscles are involuntary
Smooth Muscle
muscle found in many internal organs, including the digestive system and blood vessels. These muscles are involuntary.
Voluntary Muscles
muscles that you consciously think about using in order to get them to work – the
skeletal muscles are these
Involuntary Muscles
muscles that you do not have to think about using – smooth and cardiac muscle are this type
