Nervous System

No. It is an autonomic reflex. You brain doesn't even resister that you sneezed for a millisecond after it happened.

The human body, in its optimal condition, is capable of selecting the most appropriate molecules to rebuild a nerve. So eat in moderation a wide variety of foods and do gentle exercise. Nerves can take up to 2 years to rebuild, but they have a remarkable ability to heal. Don't forget to get ample, regular sleep.

No that's the circulatory system

D. Cerebellum \ It functions as a regulator of timing of movements. It integrates sensory perception and motor output. Many neural pathways link the cerebellum with the motor cortex - which sends information to the muscles causing them to move - and the spinocerebellar tract - which provides feed-back on the position of the body in space (proprioception). The cerebellum integrates these pathways, using the constant feed-back on body position to fine-tune motor movements. Studies of motor learning in the vestibulo-ocular reflex and eyeblink conditioning demonstrate that the timing and amplitude of learnt movements are encoded by the cerebellum

WELL the digestive system does absolutly nothin =). to keep your body healthy eat junk food and ice cream. ice cream is dairy products which are healthy, and potato chips are vegetables! see? healthy

by sending weak electrical pulses through our system. that is also one of the reasons our spine is important, because the electrical pulses are sent through it and it they stop thats when we stop being able to fully use the lower half of our body

It is caused by our brain's interpretation and reaction to the sensations of spinning motion generated by the Vestibular System of the inner ear, the Visual System's reaction to motion and the body's signals from the Skeletal System (especially the joints) indicating motion.

Our ears do more than hear. Our sense of balance is a second function of our inner ears. There are places in the inner ear that have a fluid inside, and as you move your head and body, this gel-like liquid sloshes around and moves against some tiny cilia (hair like cells). When these hairs move due to the movement of the fluid (which is caused by changes in forces on the fluid, like gravity), our brain uses these movements to interpret the body position and adds to the other senses that we use in our spatial sense. Then we can tell how we are oriented, so we can walk and balance our bodies.

There is another part of the system of balance that is in the inner ear that can also tell the brain whether we are sitting up, leaning back, or lying down, based upon the position of our head. This part uses little "stones" that move with the motion of our heads to keep track of this body positioning.

The part of the ear that works to help us keep our balance is called the Vestibular System. It includes an area known as a labyrinth, that is a maze of tubes that hold the cilia and fluids. It is on the opposite end of the labyrinth from the cochlea, which is the part of the inner ear that allows us to hear.

Along with the movement of the fluid, other signals from our bodies also are included in the brain's analysis and fine tuning of our senses of motion, movement, position, and balance. These other signals come from the eyes and vision, and also from movement and forces on the joints and skeleton (mostly in our feet and legs) that orient us to our vertical position. Our brains react to the sensations of spinning movement with safety features that create the symptom of dizziness, this will usually make us stop the the motion and lie down where we cannot be thrust against things or fall and hurt ourselves.

The Peripheral Nervous System plays a key role in our everyday lives. It controls so much of our body and is the biggest system inside the body.

The PNS, or Peripheral Nervous System is made up of neurons, a type of nerve cell. They are found often clumped in bundles, but aren't touching.

The Pns is made up of two systems:

The Sonmatic Nervous System, which controls all voluntary reactions, and the Autonomic Nervous System which controls involuntary reactions.

You can take care of the senses and the nervous system by eating foods that are high in B vitamins. These are known to support the nervous system and senses.

The two main divisions of the nervous system is the Central Nervous System (CNS), and the Peripheral Nervous System (PNS).

The CNS is made up of the Brain, Brain Stem and the Spinal Cord.

The PNS is made up of the Sensory and Motor nerves connecting to the spinal cord (and in some parts the brain).

There is also another system called the Endocrine System which can independently control digestive functioning, but that's a bit more advanced and usually isn't taught till you reach University/College.

If you want some more reading 'thinkquest' has a good tutorial.

not sure , but i think they are called motor neurons and they are part of the PNS system

Central Nervous System of the brain

When a nerve impulse (action potential) arrives at a synapse, calcium ions are absorbed into the neuron. they stimulate the synaptic vesicles, containing neurotransmitter, to fuse with the cell membrane and release the neurotransmitter into the synapse.

The brain is the main organ in the nervous system. It is connected to the spinal cord to send messages through your nervous system to the rest of your body. Your nervous system is very sensitive it hurts when you touch it.

There are several actions made by involuntary muscles such as the pumping of the heart, the expanding and contracting of blood vessels moving blood throughout the body and shivering which are involuntary muscle contractions that created thermal energy to heat up the body when its cold.
Digestion is one. Breathing is another.

The pia mater.

There are 3 layers of meninges: the pia mater adheres to the brain and spinal cord; the dura mater is next to the skull, and the arachnoid mater is in-between the two.

In the tissues C fibers or A-delta fibers carry pain within nerves to the spinal cord.

In the spinal cord pain is carried up to the brain primarily via the spinothalamic tracts.

Cranial nerve 7 is also referred to as the facial nerve. It has both sensory and motor components. Its sensory portion is responsible for taste on the anterior two thirds of the tongue as well as sensation for a small patch of skin by the ear. Its motor component is responsible for innervating the muscles of facial expression.

Phendimetrazine has a half life of about four hours. Usually, unless the person is quite obese, the drug will be out of the system within 24 hours.

The simplest type of nervous system response is a reflex loop, where the sensory input goes to the spinal chord (or brainstem, if it takes place in your neck) and from there the motor output is immediately returned. Only later the sensory input is transferred to and processed in the brain.

The cerebellum functions as a regulator of timing of movements. It integrates sensory perception and motor output. Many neural pathways link the cerebellum with the motor cortex - which sends information to the muscles causing them to move - and the spinocerebellar tract - which provides feed-back on the position of the body in space (proprioception). The cerebellum integrates these pathways, using the constant feed-back on body position to fine-tune motor movements. Studies of motor learning in the vestibulo-ocular reflex and eyeblink conditioning demonstrate that the timing and amplitude of learnt movements are encoded by the cerebellum.

People have been telling me for years that exercise releases endorphins and hormones into the blood stream and would help my anger, anxiety, depression, etc. But me, I am stubborn I wouldn't do it, until today. The whole idea is to increase your heart rate and your breathing rate. This will cause the brain to release these feel good hormones into the blood stream. Give it a try. If you can do 10 sit ups without breathing hard, up it to 15. If you can walk around the block without breathing hard, go around twice. See how many times you have to bend from the waist and slap the floor as if it were someone you were mad at, before your heart rate increases and you feel better. Take it from someone who found out for themselves - exercise can cure just about anything that ails you and more importantly it empowers you! Good luck!

Alcohol affects the nervous system by slowing your reaction time down; like your nerves and brain cells won't get messages as fast as you would like them too. Also it could make your breathing slow if not stop it.
