Nervous System

happens in the soma (aka the cell body)

motor, sensory, mixed

Saltatory Conduction

the biggest nerve in the human body is located in the prostate, as a matter of fact if the nerve in your prostate is severed it may lead to complete paralysis

There are many possible reasons. For example, perhaps she has had some bad experiences, perhaps she is worried about getting pregnant, or perhaps she is self-conscious about her body. Alternatively, perhaps she has strong religious convictions and feels that sex before marriage is a sin. Try gently talking to her about what might be making her nervous.

The autonomic nervous system functions independently and continuously without conscious effort.

Otto Loewi discovered neurotransmissions in 1921. he was a Australian scientists.

yes other than controlling electrolytes, the adrenal gland helps to regulate metabolism and interacting with sympathetic nervous system in response to stress.

they already are working together

that's how your heartbeat raises when you're scared shitless.

that's how your breathrate goes up and your face turns red when you see someone you love

the body would NOT survive if they were not working together. if that were to happen people could only be kept alive using a mechanical computercontrolled breathing apparatus controlled by a machine which measures the oxygenlevels in the bloodstream.

its known as the synapse. Through the synapse is where impulses travel from brain cell to brain cell.

A central vacuum system makes vacuuming easier than with the traditional moveable unit. It can also add value to your home, and help you save money in the long run, which has helped central vacuum systems more popular.

The nervous system relies on more rapid mechanisms of chemical and electrical transmission to propagate signals and commands. The rapid conduction of impulses is essential in allowing the nervous system to mediate short-term and near immediate communication and control between various body systems.

Nerve cells are specialized so that at one end there is a flared structure termed the dendrite. At the dendrite, the neuron is able to process chemical signals from other neurons and endocrine hormones. If the signals received at the dendrite end of the neuron are of a sufficient strength, and properly timed, they are transformed into action potentials that sweep down the neural cell body (axon) from the dendrite end to the other end of the neuron, the presynaptic portion of the axon that ends at the next synapse (the extra cellular gap between neurons)in the neural pathway. The arrival of the action potential at the presynaptic terminus causes the release of ions and chemicals (neurotransmitters).

The autonomic nervous system (ANS) contributes to the stability of the internal environment of the body (homeostasis). The autonomic nervous system continuously makes adjustments to our body to maintain equilibrium. The ANS regulates cardiac and smooth muscles and glands. One example of the function of the autonomic nervous system is when our pupils constrict when bright light is shining into our eyes. There are two main branches of the autonomic nervous system, the sympathetic and parasympathetic.

It is a norepinephrine reuptake inhibitor. Norepineprhine is a stimulating neurotransmitter. It makes you feel up, energetic, and hyperactive. It also increases your heart rate and blood pressure. When norepinephrine is released from nerve cells in the synapse to send a signal on to the next nerve cell, there is a reuptake pump that removes the norepinephrine to cut the signal off. This keeps the pathway from firing to much or too long and preserves the norepinephrine for future use. Cocaine blocks the reuptake system and makes the stimulating stronger and last longer. However it that means that you also deplete your supply of norepinephrine and "crash". This makes you feel tired. So you keep wanting more cocaine to get back to that good (high) feeling, but because you have used up the norepinephrine you never quite reach it. That makes cocaine very addictive.

Central Nervous System and Peripheral Nervous System

the CNS is the Brain and the Spinal cord which send and receive signals via the peripheral nervous system (all nerves outside the spinal cord)

So, pretty much everything really:

anything which has voluntary muscular control

some organs, including heart, lungs

temperature across the body is controlled by the hypothlamus, part of the brain

the autonomic nervous system is part of the peripheral nervous system and controls glands including sweat glands, adrenal glands, salivary glands (basically most things which result in things being secreted), sexual excitation, taste and various other miscellaneous phenomena (i.e i cant remember)

but it could be argued, by being aware of these things (via consciousness which is generated in the CNS) the CNS indirectly controls these too

(you sweat more when nervous, you behave differently when sexually aroused which would lead (hopefully) to being further aroused...


etc

Taste buds are receptors in the periphery that activate certain cranial nerves (VII, IX, & X), they therefore they may be considered to be part of the peripheral nervous system.

Given that these are columnar epithelial cells that they may actually be considered to be outside of the nervous system. They do however generate receptor potentials to certain tastants that will intern excite the peripheral axons resulting in action potentials that will eventually make into the central nervous system.

connecting mechanism is the part of female that reproduce egg cell

Many drugs will actually improve the human nervous system with almost no side effects. One of the most effective drugs that anybody could take to improve their nervous system is heroin

i think the brain sends messages between different parts of the body.

Al Gore is not the answer. The correct answer is the hypothalamus.

sympathetic nervous system.
