When you want to reach for something, pick something up, walk, or move any part of your body, the message to move, grasp, move your leg/arm, etc begins in your brain and the message [which is an electrical pulse] travels through your brain by several pathways, travels down the spinal nerves and into the extremity and the muscles targeted perform the necessary movements. Just about everything in the body is run or stimulated by electrical messages from the brain...
It could create ataxia, which would give a person a staggering, or stumbling, gait.
Your brain controls your entire body! If something is wrong with your brain the other part of the body may not be affected however your brain has led you to think that.
A skeleton I muscle pull could be caused by stretching the muscle beyond what is comfortable. This type of injury is often caused during sports or other physical activity.
There are many reasons why a person may have constant leg movement. It could be a nervous habit to constantly move their legs, or they could have a nerve or muscle disorder.
It could be muscle, tendon, or ligament. It's probably muscle tissue, since you can't move without it.
If you have eaten glass, yes, it is possible that you could excrete it in a bowel movement. This will most likely be painful and could cause internal injury.
The swelling of a joint makes movement more difficult. The idea being that moving an injured joint could cause further injury.
An injury that doesn't immediately cause pain or soreness could be a stress fracture, tendonitis, or a muscle strain. These injuries may take some time to develop symptoms as inflammation and damage gradually accumulate. It's important to pay attention to any persistent discomfort or changes in movement patterns to address these issues early on.
A charlie horse, which is a sudden and involuntary muscle cramp, typically affects the leg muscles and does not directly cause bones to break. However, severe muscle contractions could lead to a fall or awkward movement, potentially resulting in a foot injury or fracture if landing improperly. Generally, a charlie horse itself does not have the capacity to break a bone.
If it is a bad injury it could very well end your career for good. Like the footballer Marco Van Basten had to cut his career as he never recovered from it.
The factors that could affect the severity of injury resulting from contact with electricity include the voltage of the electrical current, the duration of exposure, the pathway the current takes through the body, and individual factors such as overall health and pre-existing medical conditions. Additionally, the type of current (AC or DC) and the resistance of the body can also impact the severity of the injury.
Say for e.g. that all the afferent fibres coming from the leg have been cut in half. This could block the somatosensory information (pain, temp, touch, etc) coming from the leg, leading to numbness. Motor function would be impaired due to the inability to feel and therefore react to certain stimuli. It could also lead to chronic pain (known as neuropathic pain).
