Spinal Cord

I can't think of anywhere that would try it, because the potential for paralysis is just too high, as is the cost of doing a spinal tap, and any court would consider a spinal tap an unnecessary intrusion. Any drug they need to pull a spinal tap to test for is one they're not going to be real proactive about prosecuting.

the posterior median sulcus

The vertebrae

Barring a freak accident, no.

Signals are transmitted through the spinal cord and brain via neurons.

Well they are sent through the nervous system.

Being a very serious infection, It should be treated as soon as possible. If not treated it can cause swelling of the brain, lasting impairment and can lead to coma and yes it can cause death

Poliomyelitis

The spinal cord sends messages to the brain,if we didn't have a spinal cord we couldn't do anything

no . the spinal cord starts in the 1st cervical vertebra . but it is stopped in the 2nd lumber vertebra . from this site many nerve fibres come out from the cord . these are known as cauda equina . the conical shaped end of the spinal cord is called CONUS MEDULARIS

Interneurons send messages from the spinal cord to the brain.

they go "mermff"

Conus medullaris is the lower end of the spinal cord. L1 is level 1 of the lumbar vertebral. T12 refers to the 12 thoracic pairs. It shows the position at the spinal cord where the conus medullaris ends.

in a sense, they have the equivalent but its not exactly the same.

Um... Yes, it does. That isn't really a question....

The spinal cord is the main line that brings all nerve signals back to the brain so when this is damaged it interrupts the line. When the line is damaged bad enough the signal cannot pass and therefore cannot communicate with the brain. When for example the legs can no longer communicate with the brain they can no longer receive the "orders" to move, meaning paralysis.

Occipital bone: The bone that forms the rear and the rear bottom of the skull. The occipital bone encloses a large oval hole called the foramen magnum that allows passage of the spinal cord.

Symptoms include seizures , dizziness , stroke, vomiting, uncontrollable hiccups, periodic weakness, irritability and/or changes in personality, headaches , difficulty speaking, vision problems or, rarely, brain hemorrhage.

Scientists have organized the cells that make up the nervous system into two broad groups: neurons, which are the primary signaling cells, and glia, which support neurons in various ways. The human brain contains around 100 billion neurons and, by most estimates, somewhere between 10 to 50 times as many glial cells. Bipolar ones are usually found outside the brain and interneurons are found within the brain.

- The spinal cord is the body's main nerve trunk.

- It is about 18 inches long.

- It is about as thick as a man's little finger.

- It runs down the back from the medulla oblongata, at the base of the brain.

- The spinal fluid acts as a cushion to protect the cord from damage.

it is the substance surrounding the gray matter. It is also composed of myelinated nerve fibers and makes up nerve pathways called tracts.

It is protected by your vertebrae as well as three meninges (connective tissue converings) from inner to outer; Pia mater, Arachniod mater, and Dura mater.

The brainstem contains ascending and descending nerve pathways that carry sensory input and motor output information to and from higher brain regions

Organs and parts of your body send information to the central nervous system (that's your brain and spinal cord) by electrical impulses. When the impulses reach the central nervous system, a response is triggered.

For example, if you touch a hot object, receptors on your skin will trigger an action potential in nerve cells. This action potential will be passed on to the next cell and so on until it reaches the central nervous system. The triggering of action potentials is what causes the electrical impulse. The central nervous system will then send impulses back to your hand via a motor nerve and will cause you to automatically pull your hand away.
