Although LHON generally affects young adults it can affect children as young as 1 and adults over 60.[1] Symptoms begin with

When physical exercise is stopped‚ the activities of nerves‚ lungs‚ heart and kidney gradually return to their normal conditions. Thus‚ the functions of muscles‚ lungs‚ heart‚ blood vessels‚ kidney and other organs are coordinated while performing physical exercises. In our body the neural system and the

The nervous system consists of the brain‚ spinal cord‚ and a complex network of neurons. This system is responsible for sending‚ receiving‚ and interpreting information from all parts of the body. The nervous system monitors and coordinates internal organ function and responds to changes in the external environment. This system can be divided into two parts: the central nervous system and the peripheral nervous system. Let ’s take a look at the central nervous system. Central Nervous System The

Initially‚ the stimulating current was set between 1.5 to 2 mA‚ and the frequency of stimulation was set at 2 Hz. The intensity of the stimulating current was gradually decreased as the needle approached the targeted nerve. The position of the needle was adjusted to maintain

Anatomy of Hearing including Ear Structures and Brain Structures The ear‚ an organ for hearing and balance‚ is anatomically divided into three sections: the outer ear‚ the middle ear‚ and the inner ear (Henderson). Each section contains many distinct parts that assist in the task of detecting and interpreting sound which is otherwise known as hearing (Henderson). The outer ear is composed of the auricle (pinna) and the external auditory canal (ear canal) (Sisco). The outer ear functions to
