Neurons (also called nerve cells) are a major class of cells in the nervous system. In vertebrates, they are found in the brain, the spinal cord and elsewhere in the nervous system. Their primary role is to process and transmit neural information. One important characteristic of neurons is that they can generate and propagate electrical signals.
+
{{clear}}
  
−
Neurons are discrete cells which communicate with each other via specialized junctions. Information enters the neuron primarily through the '''dendrites''' and exits through the '''axon'''.
+
{{clear}}
  
−
Neurons communicate with one another and to other cells through synapses, where the axon terminal of one cell connects to a dendrite of another.

<!-- 3. Explicar cómo las drogas afectan la función de las neuronas especialmente en la sinapsis. Hacer un compromiso de nunca tomar drogas, salvo por razones médicas. -->
−
Axons carry electrical signals from a neuron to the dendrite of another neuron. However, an axon cannot transmit these electrical signals directly to a dendrite - it needs a synapse to do this. The synapse converts the electrical impulse to a chemical reaction, which releases different types of chemicals called ''neurotransmitters.''  These neurotransmitters travel across the synapse and cause other chemical reactions which generate electricity in the dendrite.
 
  
−
The synapses can be "trained" to react strongly, weakly, anywhere in between, or not at all. It is because they can adapt that we are able to learn new things, form habits (good or bad), or suffer from addictions.
+
{{clear}}
  
−
Many drugs affect the way the synapse does its job by preventing the neurotransmitter chemicals from traveling across the synapse. Drugs can also amplify these reactions, so that they are more intense than they would have been in the absence of the drug.

−
A simple reflex is entirely automatic and involves no learning. An example is the escape reflex (e.g., the sudden withdrawal of a hand in response to a pain stimulus), or the patellar reflex (the jerking of a leg when the kneecap is tapped). Sensory neurons in the stimulated body part sends a signal to the spinal cord. Within the spinal cord a reflex arc switches the signal straight back to the muscles of the body (in this case the arm or the leg) to a motor neuron; contraction of the muscle occurs (the arm or leg jerks upwards). Only three nerve cells are involved, and the brain is only aware of the response after it has taken place.

The deep tendon reflexes provide information on how well of the central and peripheral nervous systems are working. Generally, decreased reflexes indicate a problem in the peripheral nervous system. Lively or exaggerated reflexes indicate a problem in the central nervous system.

−
'''Sensory neurons''' are nerve cells within the nervous system responsible for converting external stimuli from the organism's environment into internal electrical impulses. For example, some sensory neurons respond to tactile stimuli and can activate motor neurons in order to achieve muscle contraction. Such connections between sensory and motor neurons underlie motor reflex loops and several forms of involuntary behavior, including pain avoidance. In humans, such reflex circuits are commonly located in the spinal cord.
 
  
−
'''Neural adaptation''' is a change over time in the responsiveness of the sensory system to a constant stimulus. It is usually experienced as a change in the stimulus. For example, if you rest your hand on a table, you immediately feel the table's surface on your skin. Within a few seconds, however, you cease to feel the table's surface. The sensory neurons stimulated by the table's surface respond immediately, but then respond less and less until they may not respond at all; this is neural adaptation.

=== What spiritual lesson can be drawn from the concept of adaption?===
+
{{clear}}
−
Just as the sensory system can adapt to a stimulus until it no longer even notices it, we can adapt to a sinful environment until ''we'' no longer notice the sin. The conscience becomes numbed when ignored. We must be careful about the sorts of stimuli we allow ourselves to be subject to. Watching television programs that promote sin will dull our senses to the enormous evil of sin just as a constant stimulus to the skin will dull our perception to it.

Both the sense of taste and the sense of smell detect the chemical composition of a substance through ''chemoreceptors.''  Taste is detected by the tongue in solids and in liquids, while smell is detected by the nose in airborn substances.

There is much debate in the scientific community as to whether the "taste map" is a real phenomenon or not. Those who espouse the theory say that sweetness is best detected at the tip of the tongue, bitterness at the back of the tongue, saltiness at the sides of the tongue, and sourness further back along the sides of the tongue. Those who dismiss the theory say that each of these tastes can be detected on all regions of the tongue, and that the "taste map" is based on a misinterpretation of a German medical paper by a Harvard psychology student in 1901. Try the experiment yourself as outlined in the requirement and draw your own conclusions.

The retina is a thin layer of cells at the back of the eyeball; it is the part of the eye which converts light into nervous signals.
+
{{clear}}
  
−
The retina contains photoreceptor cells (rods and cones) which receive the light; the resulting neural signals then undergo complex processing by other neurons of the retina, and are further processed in the retinal ganglion cells whose axons form the optic nerve. The retina not only detects light, it also plays a significant part in visual perception.

{{clear}}
  
−
The optic disc is a point on the retina where the optic nerve pierces it to connect to the nerve cells inside the retina. No photosensitive cells exist at this point, and it is therefore "blind".

The three basic parts of the ear are the '''outer ear''', '''middle ear''', and '''inner ear'''.
+
Las tres partes básicas del oído son el '''oído externo''', el '''oído medio''' y el '''oído interno'''.
  
−
* The '''outer ear''' is the external portion of the ear and includes the eardrum. The pinna, which is the external portion of the ear, captures the sound and transfers them through the auditory canal to the eardrum, which vibrates and transfers the sound to the tiny bones in the middle ear.
+
{{clear}}
  
−
* The '''middle ear''' includes the ossicles (three tiny bones), two muscle tendons, and two nerve bundles. The Eustachian tube connects from the chamber of the middle ear to the back of the pharynx to equalize the pressure. That's why you can feel your ears "pop" when descending on an airplane.
+
{{clear}}
  
−
* The '''inner ear''' comprises both the organ of hearing (the cochlea) and the labyrinth or vestibular apparatus, the organ of balance located in the inner ear that consists of three semicircular canals and the vestibule. Within the cochlea are located three canals: the tympanic canal, the vestibular canal, and the middle canal. When sound strikes the cochlea, the fluid inside is moved. This fluid stimulates the organ of Corti, located within the middle canal, to interpret the sound and send the information through the auditory nerve to the brain.

===Causes of Hearing Loss===
+
{{clear}}
−
====Listening to a "walkman"====
 
−
Personal electronic audio devices, such as Walkmans and iPods (iPods often reaching 115 decibels or higher), can produce powerful enough sound to cause significant Noise-Induced Hearing Loss, even though lesser intensities of even 70 decibels can also cause hearing loss.
 
  
−
====Putting something long in your ear====
+
{{clear}}
−
Putting something long into your ear can easily puncture the eardrum. True is the saying that you should never put anything smaller than your elbow into your ear!
 
  
−
====Being in the front row at a loud music concert====
+
{{clear}}
−
As in the case of the "walkman" question, exposure to loud sounds can damage your hearing. Live music concerts are an even greater threat to the hearing because they are so much louder than a personal electronic device, even when the listener is ''not'' close to the speakers.
 
  
−
====Not treating an ear infection properly====
+
{{clear}}
−
An ear infection causes tissues inside the ear to swell, and this can close the tubes inside. When the tubes are blocked, pressure in the ear does not equalize, and that makes it more difficult for the eardrum to vibrate. This causes a reduction in hearing. In severe cases, the pressure imbalance can cause the eardrum to tear.
 
  
−
====Standing behind a jet at an airport====
+
{{clear}}
−
As in the case of the loud concert, very loud noises - even brief ones - can cause severe damage to the ear, including tearing the eardrum and damaging the hair cells in the inner ear.

This is the output recorded by the first electroencephalogram (EEG) administered by Hans Berger in 1929. Electroencephalography is the measurement of the electrical activity of the brain by recording from electrodes placed on the scalp or, in special cases, on the cortex. The resulting traces are known as an electroencephalogram (EEG) and represent so-called brainwaves. This device is used to assess brain damage, epilepsy and other problems. In some jurisdictions it is used to assess brain death.

A polygraph or lie detector is a device which measures and records several physiological variables such as blood pressure, heart rate, respiration and skin conductivity while a series of questions is being asked, in an attempt to detect lies.
 
  
−
A typical polygraph starts with a pre-test interview designed to establish a connection (or find a control) between the tester and the testee and to gain some preliminary information which will later be used for "Control Questions " or C (see below). Then the tester will explain the polygraph, emphasizing that it can detect lies and that it is important to answer truthfully. Then a "stim test" is often conducted: the testee is asked to deliberately lie and then the tester reports that he was able to detect this lie. Then the actual test starts. Some of the questions asked are "Irrelevant " or IR("Are you 35 years old?"), others are "probable-lie" Control Questions that most people will lie about ("Have you ever stolen money?") and the remainder are the "Relevant Questions " or R the polygrapher is really interested in. The different types of questions alternate. The test is passed if the physiological responses during the probable-lie control questions are larger than those during the relevant questions. If this is not the case, the tester attempts to elicit admissions during a post-test interview ("Your situation will only get worse if we don't clear this up"). These admissions are the main goal of the test.

The accuracy of polygraph tests is a matter of considerable controversy. While some claim the test to be accurate in 70% - 90% of the cases, critics charge that rather than a "test", the method amounts to an inherently unstandardizable interrogation technique whose accuracy cannot be established. Critics also argue that even given high estimates of the polygraph's accuracy a significant number of subjects (e.g. %10 given a %90 accuracy) will appear to be lying, and would unfairly suffer the consequences of "failing" the polygraph. It is interesting to note that, so far, not one scientific study has been published that proves the validity of the polygraph test. Polygraph tests have also been criticized for failing to trap known spies such as Aldrich Ames, who passed two polygraph tests while spying for the Russian government.

Alzheimer's disease is a degenerative disease of the  brain. It is the most common cause of dementia and is characterized by progressive intellectual deterioration together with declining activities of daily living and behavioral changes. The most striking early symptom is memory loss (amnesia), usually in the form of minor forgetfulness that becomes steadily worse as the illness progresses, with relative preservation of older memories. As the disorder progresses, intellectual impairment extends to language, coordinated movement, recognition  and functions such as decision-making and planning.

Multiple sclerosis (MS) is a chronic disease that affects the brain and spinal cord. MS can cause a variety of symptoms, including changes in sensation, visual problems, muscle weakness, depression, and difficulties with coordination and speech. Although many patients lead full and rewarding lives, MS can cause impaired mobility and disability in the more severe cases.
