Nervous System

No a person cannot survive without the circulatory system. This is because, without the circulatory system,

# Transport of nutrients to cells cannot take place. # Waste materials from cells cannot be transported to the excretory organs. # Homeostasis cannot be maintained.

The division of the autonomic nervous system that arises from spinal nerves T1 to L3 is the sympathetic division. This division is responsible for controlling involuntary body functions.

It involves many sistems but the one that controls it is the central nervous system. Though there are a few that also work with homeostasis, for example, the peripheral nervous system plays an important role during this process.

The spinal cord is posterior to the chest.

Balls have no nerves, they are inanimate objects.

XI- Accessory (mixed nerve): controls the muscles of the head, neck movement, muscle sense.

Cone cells, or cones, are photoreceptor cells in the retina of the eye which function best in relatively bright light. The cone cells gradually become sparser towards the periphery of the retina.

GENERIC NAME: oxycodone and acetaminophen BRAND NAMES: Percocet, Roxicet, Tylox, Endocet DRUG CLASS AND MECHANISM: Oxycodone is a narcotic analgesic (pain-reliever) and a cough suppressant that is similar to codeine and hydrocodone. The precise mechanism of pain relief by oxycodone and other narcotics is not known. Acetaminophen is a non-narcotic analgesic and antipyretic (fever reducer). Acetaminophen relieves pain by elevating the pain threshold. It reduces fever through its action on the heat-regulating center of the brain. The combination of oxycodone and acetaminophen achieves greater pain relief than either taken separately. For more information on acetaminophen, please see acetaminophen (Tylenol).

In human anatomy the spinal column has been divided into four sections for reference and specificity; the cervical spine, the thoracic spine, the lumbar spine and the sacral spine. The Cervical Spine is the section in the neck area comprised of seven vertebrae starting at the base of the skull and counting down the spine. To refer to the individual vertebrae in that area you would again start at the base of the skull with C1, and then count down to the last cervical vetebra, C7. The cervical spine is made up of C1, C2, C3, C4, C5, C6, and C7. The Thoracic Spine is the next section down the back located in the chest area and is comprised of twelve vetebrae. The ribs connect to the thoracic spine and create a strong skeletal structure that protects the vital organs. The vertebrae in the thoracic spine start with the eighth vertebra down which is called T1 and continued through T12. The third major region of the spine, the Lumbar Spine,starts below the thoracic spine with the thirteenth vertebra, L1, and continues through L5 for most people, although it is not uncommon for some people to have a sixth Lumbar verterbra, L6. When you have a low backache, it is usually in the area of the Lumbar Spine since it is the part of the vertebral column that supports most of the body's weight. The final section of the spine continues from the last lumbar vertebra, number seventeen (or eighteen, if there are six in this section) and down to the pelvis. This is called the Sacral Spine and has only one vertebra, the sacrum, called S1, and the coccyx bone which is also known as the tail bone. The sacrum and coccyx are uniquely shaped.

If your body did not have a nervous system, you would have no physical feeling. Your muscles would be useless. Dangerous objects could be handled without even knowing the damage that was being done on your body (ie. stovetops, knives, fire, sub-freezing temperatures etc.) Oh, and sex would not be possible. One could not ejaculate if there was no feeling in his penis.

Compression of what nerve causes facial numbness from the upper palate to the eye on one side of face only?

Probably the trigeminal nerve. It causes a condition called Bell's palsy. If your one eye is drroping and your smile droops on the same side, go to the doctor. There is treatment for this and it won't be permanent. Some doctors now think this is caused by a virus and may give you Valtrex and /or steroids, short term.

The terms antagonist/agonist only apply to 'exogenous' compounds, namely drugs and toxins, and not neurotransmitters - which are commonly classed according to whether they are excitatory or inhibitory. Examples of a the latter include GABA and glycine.

Myelin is a fatty substance that insulates and protects nerve cells and allows them to transmit electrical signals quickly.

say its like your humorous bone, OK? so then you him the humorous bone the nerve sends a shocking feeling to your hand. so basically it sends messages to the brain. or else if you have a cut on the back of your knee and you don't know that your bleeding. well your just going to bleed gushes of blood everywhere.

The Remaining Schwann Cells

schwann cells, after injury and disruption to target, the remaining schwann cells undergo a rapid mitotic division until the target tissue is reached and the successful pathway is regenerated under the structural guidance of the schwann cells,

The emergency, or "fight or flight" part of the nervous system is the sympathetic nervous system. The parasympathetic nervous system produces a "rest and digest" response.

The action potential increases slightly because more neurons are being stimulated.

The tenth carotid nerve of human is the vagus nerve.
A cranial nerve that's a major output of the parasympathetic nervous system. The sympathetic system is fright, fight, or flight enhancer, the parasympathetic is the opposite ... sort of relax and digest your last meal. Slows the heart and increases digestion.

Yes, when consumed by man, the narcotics act on the central nervous system. The narcotics acts on the central nervous system that leads to lack of coordination of the various body parts.
