Tinnitus referred as ears ringing‚ in humans‚ can be caused by a variety of factors; such as high-level sound exposure‚ ototoxic drugs‚ and hearing loss. It is basically the self perception of sound in the absence of acoustic stimulation. the sound waves hit the outer ear and converge into the ear drum. The vibrations at ear drum are transferred into the inner rear through the middle ear. Once the sound waves reach inner ear‚ they travel through the cochlea towards the organ of corti. Further the

Neurogenic Shock Neurogenic shock is a type of shock that is caused by a spinal cord injury that affects important nerves in the nervous system. Injury to the nervous system causes the walls of blood vessels to relax‚ which increases the blood pressure. Neurogenic shock mainly affects the spinal cord. The spinal cord consists of nerves that carry incoming and outgoing messages between the brain and the rest of the body. Neurogenic shock occurs when a spinal cord injury happens‚ particularly involving

PROPRIORCEPTION. Propriorceception is essentially the ability to sense the position‚ alignment and movement of one’s body and its parts in space. For example‚ if your eyes were closed‚ you’d still know where your hands are without much thought due to proprioreception. Also when you are standing proprioreception allows you to be aware of where your limbs are and therefore you can make any necessary adjustments if you felt out of balance. This ability to know where your body parts are in 3-dimensional

Every year‚ about 110 cases of botulism are reported in the United States. About 25% of the cases result from food‚ while 72% are infant botulism and 3% are wound botulism. Food-borne botulism is usually caused by eating home-canned foods that are contaminated with the toxin botulin. Botulin is produced by Clostridium botulinum‚ which is the name of a group of bacteria commonly found in soil. The bacteria grow best in low-oxygen conditions. The bacteria form spores that enable them to survive

How neurons communicate Neurons are the specialized cells which make up the body’s nervous system. These nerve cells process and transmit information from one part of the body to another. For example‚ if you were to touch a candle flame for more than an instant‚ pain nerves also known as receptors that are in your finger would send a message up through your hand and arm to the spinal cord and then to the brain. The brain which in turn records pain and sends the messages back down to various parts

The central nervous system (CNS) is that portion of the vertebrae nervous system that is composed of the brain and spinal cord. Together with the peripheral nervous system (PNS)‚ the other major portion of the nervous system‚ the CNS coordinates the body’s interaction with the environment. The CNS is contained within the dorsal cavity‚ with the brain in the cranial subcavity (the skull)‚ and the spinal cord in the spinal cavity (within the vertebral column). Then human nervous system is the most

Interactions between nicotine and baclofen Activation of nAChRs within different areas of brain enhances release of several neurotransmitters including: glutamate‚dopamine‚norepinephrine‚ serotonin‚ ‚gamma amino butyric acid(Wonnacott‚ 1997)‚ (Benowitz‚ 2008) The regulation of releasing these neurotransmitters which is induced by nicotine`s effects depending on various postsynaptic receptors‚ is the usual mechanism by which nicotine modulates behavior (Benowitz‚ 2008).As we mentioned above
