The bladder receives information through the lumbar nerve plexus that is formed from spinal nerves that extend from the spinal cord and exit through the vertebral foramen (holes in between spinal bones )of the lower lumbar spine. Because the information comes from a nerve group, or plexus, it receives nerve impulse from more than one level of spinal cord.

There are several nerve branches in the spinal column. The most popular being the sciatic nerve which branches of the lumbar spine into the legs.
Yes. When a nerve is wrapped up against a part of the spine in the lower back, it causes pain. An Anthropologist can put someone under anesthesia and then move the nerve further away from the spine.
The sciatic nerve is the largest and longest single nerve in the human body, about as big around as a thumb at its largest point. The nerve originates in the lower spine as nerve roots exit the spinal cord (through the bones in the spine), and extends all the way down the back of the leg to the toes. The sciatic nerve is actually a combination of nerves. It is formed on the right and left hand side of the lower spine by the combination of the fourth and fifth lumbar nerves and the first three nerves in the sacral spine. Each nerve exits the spine between two vertebral segments and is named for the segment above it.
The arrangement of the bones in the vertebral column start with the cervical spine. The cervical spine controls the head and neck. The next section of the vertebral column is the thoracic spine which controls the truck and mid back. The last vertebral column is the lumbar spine which is responsible for the legs.
The sciatic nerve is formed by several nerve roots exiting the lower spine, specifically from the L4 to S3 segments of the spinal cord. These nerve roots then come together to form the largest nerve in the body, the sciatic nerve, which runs from the lower back down through the buttocks and into the legs.
The sciatic nerve is the largest nerve in the body, running from the lower back down the back of each leg. It is made up of several nerve roots from the lower spine. When the sciatic nerve is compressed or irritated, it can cause a condition called sciatica, which leads to pain, numbness, or tingling in the lower back and legs. This is often due to a herniated disc or bone spur putting pressure on the nerve.
if you break part of your spine the "plates" in your spine move which wreaks the nerve cells in the part of your back. Messages from your brain can not get pass that broken part. So if your neck is broken you are paralyzed from the neck down.
The sciatic nerve is the largest nerve in the human body and runs from the lower back down through the buttocks and into the legs. It branches off from the lower spine and travels down the back of each leg, providing sensation and muscle control.
The nerve that approaches the knee and divides into the fibular and tibial nerves is the sciatic nerve, which is the largest nerve in the body. It originates from the lower spine and travels down the back of the thigh, eventually splitting into these two branches at the knee.
In simplified terms, the sciatic nerve is a nerve that runs from your spine to your legs. Irritation of the sciatic nerve, commonly known as sciatica, is a medical condition where the nerve root, upon leaving the spine is irritated. The irritation of these nerve roots can cause back pain, and if the nerve roots of the sciatic nerve are irritated, then pain can be felt in the leg of the affected side, and this is known as 'sciatica'. The nerve roots can be irritated in many ways: the discs between the lumbar vertebrae can protrude and squash the nerve root as it leaves the spine (such as in a lumbar hernia, after lifting a heavy weight in a bad way for exemple); the spine can like any other articulation can tend to wear out, and the inflammation or formation of small protruding bones can also cause the nerve roots to be irritated. In the case of pregnancy, sciatica can happen. As the pregnancy evolves, the weight of the fetus will mean that the mother's spine slightly changes in shape to better support the weight she is carrying. As the mother has to hold herself in a unusual position, it is possible that the nerve roots passing by the vertebrae on their weigh out of the spine get slightly compressed and cause sciatica, assuming no other underlying condition exists.
With the sphincter muscle, found at the junction of the bladder and the urethra. Involuntary muscles. There is a whole part of the brain that controls involuntary responses and functions. Example:breathing, heart pumping blood.
The sciatic nerve is the largest single nerve in the human body; it runs from each side of the lower spine through deep in the rear and back of the thigh and all the way down to the foot, connecting the spinal cord with the leg and foot muscles.
