A. An anticholinergic is a drug used in the treatment of diseases such as asthma, muscular spasms, insomnia and gastrointestinal cramps (Healthline, 2016). The drug is also used with anesthetics as it inhibits the action of parasympathetic nerve impulses by preventing acetylcholine reaching the receptor cells of nerve impulses. This may lead to memory loss, confusion, drowsiness and even sedation. These effects are more pronounced in old-aged people. Loss of muscular strength and fainting is a symptom which could be seen in the patient. Use of anticholinergic drugs is not recommended for patients with conditions like glaucoma, hyperthyroidism, heart ...

They extend from the spinal cord to the receptor cells located in all parts of the body. The primary function of sensory area to carry impulses from the receptor cells to the brain for interpretation. These impulses can be those of sensations like touch, pain, smell, taste and sight.

It is clear that swimmer’s ear also causes inflammation, fullness in the inner ear and possible hearing loss (Hui, 2013).It is also true that most of the diagnosis is done by the observation of the outer ear such as the pinna. In some cases, the inflammation of the outer ear might be caused by complications in the fluids found in the inner ear. An otoscope could, therefore, be used to ...

Sound is the sensation that is produced when the longitudinal vibrations of molecules from the external environment hit the tympanic membrane. Such vibrations in the external environment are called sound waves. Sound waves are produced when vibrating molecules generate changes in pressure. The speed of sound waves in air is approximately 344m/s at 20 degrees at sea level. An increase in temperature and altitude increases the speed of sound. Other media conduct sound at different speeds. For instance, in fresh water, sound travels at a speed of 1450m/s. Sound can be referred in a perceptual response and a physical stimulus. Sound reaches ...
Human perception of sounds is not only performed by an ear as a part of the body. In fact, a person hears through the organ of hearing, which has got complex structure. The ear is only a visible part of it.
Auricle or pinna essentially acts as a funnel through which a person catches vibrations in the air. Coming through the auditory canal, they affect the eardrum – a thin membrane that separates the outer and middle ears.
Then the eardrum vibrations are transmitted to the auditory ossicles and reach the inner ear, the main part of which is an organ called the bony ...

What happens with a patient who develops a cataract?
A cataract is the opacification of the crystalline lens in the eye. In a patient with cataract, there is progressive loss in the transparency of the crystalline lens; this is due to changes in the density of the epithelial cells. There is also a derangement in the fiber of the lens cells. Lens transparency can also be because of deposition of minute epithelial masses of apoptotic lens tissue in the substance of the lens leading to disruption of the internal homeostatic mechanism of the lens and accelerating the process of cataract formation. (Vincente Ocampo, 2012)
Cataract initially leads to an increase ...
