3 joints of the human body? PLZ HELP!!!?!


Question: 3 joints of the human body? PLZ HELP!!!?
What are the 3 joints of the human body and what exactly do they do?

Answers:

The types of joints that we have in the human body are hinge joints, saddle joints, ball-and socket joints, pivot joints, gliding joints and immovable joints. Hinge joints, your elbow or knee for example, is a joint of bone that allows for movement in one direction. Saddle joints, your thumb being one, allow for movement in two planes, the sagittal and frontal planes. Ball-and-socket joints, your shoulder or hip for example, allows for 360* movement. Pivot joints, such as the joint allowing humans to rotate their skull and are also found in the forearms and knees, allows for rotation. Gliding joints, such as your wrist for example, is a joint in which the bony surfaces that the joint holds together are flat or slightly rounded. Immovable joints, such as the fibrous connections between bones in the skull, are joints that cannot move, and are also known as synarthrotic.

I don't really know the functions of each, but I think with a bit of thinking and the information given here, that the purpose and function can be figured out.

I hope this helps.
