Skeletal--->Nervous The nervous system and skeletal system interact in many ways. The first would be that white blood cells made in bone marrow are used in the immune system to get rid of pathogens. They cells develop partly in the bone marrow, but then go to the thymus, a part of the brain, to develop further. Another interaction is that nerves send a message to some skeletal muscles so they can contract and pull on bones. The nervous system controls the body's reaction to the environment, as well as it's reaction to conditions inside the body. When the system tells muscles to contract, it is reacting to something in the environment. The muscle contraction causes tendons to pull on bones, which allow for movement in that area.The third interaction is that there are three bones in the ear, the hammer, anvil, and stirrup, that knock each other and vibrate, causing the liquid in the cochlea to make a message allowing you to hear. The ear is a receptor organ. That means that it gives information about the environment to the brain. The brain then interprets this information. The hammer, anvil and stirrup bones vibrate when sound waves come in through the ear canal, making the ear drum vibrate, which makes the bones vibrate. the last bone knocks up against the cochlea. The liquid in the cochlea vibrates. The alternating changes of pressure cause the hair cells to move. This movement makes the the sensory hair cells to send impulses along the auditory nerve to the brain. The bones are key to the hearing process, because without them there, nothing would bump the cochlea! That would mean that no message would get sent to your brain, and you wouldn't be able to hear anything! Imagine how much harder your life would be if you couldn't hear! The final interaction is that the cranium protect the main part of the nervous system, the brain, and that the vertebrae protect the spinal cord. The brain is very important to the nervous system- it is where we translate sounds into music and differ between types of smells and tastes. Receptor organs GET this information, but the brain CHANGES that information (in the form of impulses) into something that makes sense to us. The brain is SO important and SO fragile, which is why the cranium is there to protect it. The spinal cord is also an important part of the nervous system- it's like the highway for nervous messages and nerves. Any message going to body cells travels down the spinal cord before reaching regular nerves, and then finally the cells. The vertebrae looks almost like a series of small doughnuts stacked on top of each other. The spinal cord is protected from harm right in the center holes of the bones.
