The reason that you cannot feel two bones rubbing together when they bend at the joint is because the two bones are separated by a layer of muscle and cartilage. It is possible for the cartilage and muscle to be torn, though, and it is possible to feel the bones rubbing together. This is very painful and in many cases will require surgery.

How can a broken bone affect the human body?
With regards to movement and support to the body, a broken bone will reduce the ability of the bone to support the weight of the body. A bone acts as a frame for the muscle to pull against and thus enable movement. The muscle is unable to pull against a broken bone and therefore movement is reduced or not possible at all.
The movement of water across a membrane is termed?
it is called osmosis and it is the net movement of water particles across a semi-permable membrane against the concentration gradient!
What do active transport and osmosis have in common?
They are both the movement of particles but active transport uses energy, so it can move against the concentration gradient.
What is the movement of molecules across a membrane against their concentration at the expense of ATP energy called?
This process is called active transport.
In order for molecules to move against the concentration gradient?
When you have one concentration (amount) of a molecule, connected to a higher or lower concentration through a permeable membrane (bridge), there is a natural force (heat) pushing the molecules to go from the higher concentration to the lower concentration until both sides have balanced (it is also called diffusion, this process is related to the laws of thermodynamics). Anyway this force the measurement of force for this movement is called the concentration gradient. For a molecule to move against this natural force is to against the concentration gradient, it requires an energy GREATER then that from diffusion or heat to push it. An example would be when there is an opposing electrical force strong enough that may push an electrically charged molecule against its concentration gradient.
How are the skeletal and muscular systems connected to allow an animal to accomplish movement?
muscles help to tie bones of the skeleton together and supplement the skeleton in supporting the body against the gravity.
