Spinal Cord

The cauda equina is a cluster of nerves located approximately in the middle of the back. Its purpose is basically to transmit messages from the upper part of the human body to the lower.

The nerves, spinal cord and brain work together to keep you aware of what's going on with the body and get messages out to the muscles and other body systems. Not all nerve messages are handled by the brain though and so not all involve the spinal cord, the main path way to the brain from the body's nerves. In addition there are some other routes for information to get to the brain.

Some areas of the body are under "local control" and do not require brain commands or the use of the spinal cord. This would include the involuntary muscles ( e.g. you don't have to think Beat ... beat ... beat at your heart all day) and glands which secrete hormones and enzymes in response to chemical conditions in the body (e.g. no brain commands go to the pancreas)

Some nerve responses only go as far as the spinal cord and then are bounced back to the originating area without the brain's input. An example, if you prick your finger the pain input is bounced back to the arm muscles to pull your finger away without the brain's input. A secondary message goes to the brain to notify it of the pain.

A lot of the body nerve input does go through the spinal cord. Muscle position information, pain messages, pressure, heat. A lot of the messages from the brain follow the return route (muscle movement)

There are however some nerve impulses which get hard wired directly into the brain. As an example the eyes contain the optic nerves which are essentially brain tissue poking through the front of your face. This results from the need to have almost instantaneous awareness of what is going on visually. Routing nerve messages through the spinal cord would take too long and the lateness of the information would make hunting (like a bird chasing flying insects) or jumping from limb to limb (as a monkey does) impossible.

yes it is encased to keep for any mishaps occurring and damaging the spinal cortex:)))

You might need surgery for focal left foraminal disc protrusion that contacts the exiting left L4 nerve root if the protrusion is affecting your quality of life. This type of surgery is most often accomplished via a very small incision.

Since the hooks and rods of spinal instrumentation are anchored in the bones of the back, spinal instrumentation should not be performed on people with serious osteoporosis. To overcome this limitation, techniques are being explored.

• nuclei of the posterior horn (sensory) = substantia gelatinosa of Rolandi + Nucleus proprius + Clark's dorsal nucleus
• nuclei of the anterior horn (motor) = 2 medial + 1 central + 2 lateral groups
• nuclei of the lateral horn (autonomic) = sympathetic (T1-L2/L3) + parasympathetic (S2-S4)

Not really. The spinal cord runs through the spinal canal, which is anterior (in front of) the spinous processes, betwen two lamina and two pedicles, and posterior (behind) the vertebral body.

An arachnoid mater is a membrane which protects the brain and spinal cord below the dura mater and above the subarachnoid space and the pia mater.

Neck fracture can easily cause damage to the spinal cord, but this does not always happen, especially if the neck has been supported and immobilised quickly and properly.

Masses that grow within the brain or spine. The growths usually cause many complications with growth and other such factors. The masses could be cancerous or not.

L3-L4 refers to the location of the spinal stenosis (narrowing of the spinal canal). The problem is found between the third and fourth vertebrae. Grossly unchanged means it appears the same to the naked eye (albeit on imaging studies) as the last time they looked.

The spinal cord is posterior to the sternum.
