What does the spinal nerves from the sacral region of the cord innervate?
leg
What part of the nervous system is responsible for the reflex arc?
The peripheral nerves and the spinal cord. When a reflex starts, the peripheral nerves in the arms or legs send a signal to the spinal cord. Normally that signal is sent on to the brain for processing. In a reflex, the spinal cord itself sends a response back to the arm or leg to move immediately.
Which part of the nervous system do the nerves in your arm and leg belong to?
They belong to the peripheral nervous system, as opposed to the central nervous system (as they are to be found on the periphery of the body).
How are stretch reflexes used to find a spinal cord injury?
Stretch reflexes are used to determine which areas of the body that the central nervous system does not respond to. For instance, if you tap your knee to check reflex, and the leg doesn't move, then you will know that the peripheral nerves that lead to the knee are non-responsive or that the brain isn't receiving a signal from that area.
What does no reflexes in right leg mean?
No reflexes in the right leg could indicate a potential neurological issue affecting the spinal cord or nerves in that area. It could be due to conditions such as nerve damage, spinal cord injury, or a neurological disorder. Further evaluation by a healthcare provider is recommended to determine the underlying cause and appropriate treatment.
How many nerves are in the leg?
There are numerous nerves in the leg, including the sciatic nerve, femoral nerve, and tibial nerve. These nerves innervate different areas of the leg, providing sensation and motor function.
Purpose of nerves?
Nerves send information to your brain such has if something is hot or cold. And your brain also sends messages through your nerves such has lift the arm, left leg forward, right leg up, so on and so forth
What is the main purpose of the central nervous system?
To protect you from being harmed. The spinal cord gets different types of messages from your nerves, that goes to your brain and the brain sends a what to do message to the spinal cord so the spinal cord reacts real fast moving through your nerves to the part that's hurt to put your leg or whatever is hurt away from harm. And all this happens in less than a second! Amazing ain't it? EXAMPLE: if you put your hand in hot water your nerves gets a message through and gives it to the spinal cord and it reacts fast because it knows that your in pain!
Do you have bone in the brain?
No, the part of the body that controls your body is the brain. It works by sending messages via the nerves and going to the part of the body. For example, if you wanted to move your leg, your brain will send a message to your nerves via the spinal cord.
What are the common symptoms and treatment options for lower lumbar spinal stenosis?
Common symptoms of lower lumbar spinal stenosis include back pain, leg pain, numbness, and weakness. Treatment options may include physical therapy, medications, epidural injections, and in severe cases, surgery to relieve pressure on the spinal cord or nerves.
What if you have mild left foraminal narrowing at l5-s1?
The vertebral foramen (the hole that allows a nerve to extend from your spinal cord down to the left leg) between your 5th lumbar vertebra and the sacrum has been narrowed. This is, more than likely, due to a disc herniation. As the foramen narrows, the spinal nerve can become compressed. The components of the body that receive their information from that nerve become affected. This usually involves a shooting pain sensation (from the left buttock, possibly down the back of the leg, possibly down the inside of the calf, possibly to the big toe), muscle weakness in the leg (usually presenting as a foot drop or difficulty raising the foot), or both. Sometimes the bladder or the prostate gland can be affected. Best see a chiropractor. Thomas A. Bea
