Structure of the bones:

Cartilage:

Joints:

Ligaments:

The structures that made the bone are: COMPACT BONE, BONE MARROW (that produce blood cells), SPONGY BONE and OUTER MEMBRANE. Study Guide Science- Question 6

A tissue that protects the end of the bones.

Is where two or more bones meet.

Tipes of Movable Joints:

Hinge:

Pivot

Ball and socket:

Allows bones to move and Rotate in nearly all the directions. Ex: Hips and shoulders.

Allows bones to move back and forth in a single direction. Ex: Fingers, Elbowls and Knees.

Allows bones to rotate. Ex: Neck and Arm (below thw elbow)

It is a tissue that connects the bones.

Arms:

Hips and legs:

Humerus, Ulna and Radius.

Femur, Fibula and Tibia

Gliding:

Allows the bones to glide past one another in any direction along the plane of the joint. Ex: Wrists and Ankles
