Eventually, the bronchi become known as bronchioles â the smallest air tubes in the lungs. This system of air tubes can be thought of as an upside down tree, with the trachea being the main trunk and the bronchi and bronchioles being the branches. The medical term for all the air tubes is 'the respiratory tract'.
An injury to the vertebrae or discs in your neck can cause pain, numbness, or weakness in your shoulder, arm, wrist, or hand because the nerves that extend out from between the neck provide sensation and allow for movement in these areas.
This can cause inflammation and irritation of the synovial lining, which produces the synovial fluid that helps protect and lubricate the joint. When arthritis affects the joints of the hands, it can cause pain and stiffness. That pain can get worse whenever you use the hand a lot for repetitive tasks. For example, typing on a computer keyboard or gripping utensils in the kitchen can cause discomfort. You may also lose strength in your hands.
