Coma, from the Greek word " koma, " meaning deep sleep, is a state of extreme unresponsiveness, in which an individual exhibits no voluntary movement or behavior. Furthermore, in a deep coma, even painful stimuli (actions which, when performed on a healthy individual, result in reactions) are unable to affect any response, and normal reflexes may be lost.

Dizziness is lightheadedness, feeling like you might faint, being unsteady, loss of balance, or vertigo (a feeling that you or the room is spinning or moving). Most causes of dizziness are not serious and either quickly resolve on their own or are easily treated.

Dizziness is a general term that describes sensations of imbalance and unsteadiness, such as vertigo, mild turning, imbalance, and near fainting or fainting. Feelings of dizziness stem from the vestibular system, which includes the brain and the parts of the inner ear that sense position and motion, coupled with sensory information from the eyes, skin, and muscle tension.
|
|
When the brain receives conflicting signals, or when there is a problem with blood flow, dizziness or fainting can occur.

Can arthritis in neck and shoulders be the cause of "positional vertigo?"

The heart rate, usually measured by checking the arterial pulse or sounds counting the
times of the heart beat, is considered one of the vital signs. Vital signs - body
temperature, pulse, breathing rate, and blood pressure provide information about the state

Prolonged exposure to excessive noise can result in permanent hearing loss. Many occupations have increased risk of hearing damage, and in such cases ear protection should be worn.
|

People who are tone deaf, or amusic, are unable to distinguish differences in pitch, and may have a similar difficulty with rhythm. Research suggests this may be due to weak connections between the parts of the brain responsible for processing music.

Hearing loss is any degree of impairment of the ability to apprehend sound. Sound can be measured accurately.
|
|
Hearing impairment is the temporary or permanent loss of some or all hearing in one or both ears. There are three types of hearing impairment that occur in young children: conductive hearing loss, a usually temporary interference with the reception of sound from the outer ear to the middle or inner ear sensorineural hearing impairment, a permanent abnormality of the cochlear hair cells of the inner ear, the auditory nerve, or the auditory center of the brain mixed hearing impairment, a combination of conductive and sensorineural impairments Hearing impairments also are classified as prelingual (occurring before a child learns to speak) and post-lingual (occurring after the child has acquired language).

Hearing begins in the womb- pregnant women have reported feeling the fetus move in response to loud noises at 31 weeks (7 weeks before full-term delivery). Newborns are sensitive to the location, frequency, pitch, and volume of sounds.
|

Hearing loss can be caused by many things - some reversible such as wax buildup in the
ear canal or ear infections with fluid build up. Some hearing loss is irreversible - that
due to mechanical problems within the ear itself, or sensorineural problems within the
inner ear.

Unconsciousness is when a person is unable to respond to people and other stimuli around him or her. Often, this is called a coma or being in a comatose state. Other changes in awareness can occur without becoming unconscious. Medically, these are called "Altered Mental Status" or "Changed Mental Status." They include sudden confusion, disorientation, or stupor. Unconsciousness and any other SUDDEN change in mental status must be treated as a medical emergency. If someone is awake but less alert than usual, ask a few simple questions -- What is your name? What is the date? How old are you? If the person doesn't know or answers incorrectly, then his or her mental status is diminished.
