This article focuses on hyperacusis is‚ how it works‚ and the different treatment approaches based on what is currently known. Hyperacusis is defined as “ unusual tolerance to ordinary environmental sounds and‚ more pejoratively ‚ as consistently exaggerated or inappropriate responses to sounds that are neither threatening nor uncomfortable loud to a typical person‚” (Baguley 2003) I learned in class that due to cochlear hearing loss caused by the loss of outer hair cells‚ patients have a smaller

2.2 Electrical Communication Study Guide by Hisrich 2.2.a How does communication happen within the body? Electrical Signals Nervous System Chemical Signals Endocrine System The nervous system is made up of neurons. Neurons communicate just like people do‚ but they send messages using action potentials (electricity passing through their axons). Each neuron picks up signals at its dendrites‚ passes the signals down the axon‚ into the axon terminals‚ and into the synapses. The synapse

evasion of host response Phenotypic switching Adhesion‚ evasion of host response Table 1: Adapted from Naglik et al (2003) Adherence Candida albicans is known to present cell-surface proteins that are involved in the process of adhesion to mammalian epithelial cells which in turn contributes to its virulence. The Als (agglutinin-like sequence) family are encoded by eight gene loci‚ Als1-Als7 and Als9 (Murciano et al‚ 2012) and are probably the best characterized group of adhesion factors. The

I was compulsory to listen to my body’s gestures which sometimes resulted an earlier assent from a dive compared to other members of the group. Diving within your personal limits is important as everyone is different and your body knows when you’ve had enough. It is important not to force the body as it could embolden the risk of over exertion and hypothermia

a diving tour for several days. It would be important to have a professional underwater camera to document 10-15 dives. Normally one does a maximum of two dives per day. One is normally underwater for an hour on each dive and the body is affected by the strain of moving underwater and the water pressure. Thus‚ two dives and one feels exhausted. I was planning to do only one dive because of the buildup of gases in my blood system and we were scheduled to fly to Sydney the following day. One has

acronym for "self-contained breathing apparatus"‚ Allows divers to dive deeper and stay submerged longer. Scuba comes a long way from other forms of diving by using an air-tank and regulator. This is what allows them to stay under longer and dive deeper. Scuba originally began with military and commercial applications‚ where it is still used today. But now‚ by far the largest group of divers is "Recreational Divers". These dives are practiced at depths of less than 130 feet‚ from these depths‚ divers

view the front of the eye. Pupillary light reflex is tested which involves shining a bright light into the eye and observing reflexive pupil constriction in the eye. The consensual pupillary reflex is observed in the eye that is not stimulated‚ but both the direct and consensual pupillary light reflexes depend on the function of a reflex arc. The reflex arc involves cells in the retina that travel through the optic chiasm and tract. Though the light reflex does not necessarily mean normal visual function
