HYPONATRAEMIA IN THE NEUROSURGICAL PATIENT INTRODUCTION Sodium the most abundant electrolyte in the human body‚ and therefore the osmolality of body fluids is strongly dependent on its concentration. Osmolality in turn is important in maintaining homeostasis within the brain. Ironically‚ dysfunction of the brain can cause changes in sodium homeostasis. To avoid neurological deterioration‚ morbidity or mortality the sodium level must be corrected promptly. The two most common causes of hyponatraemia

Case Study #3 Anabolic Steroids – The Nervous System The main purpose of the Nervous System is communication through electrical impulses. The nervous system allows for the coordination of all systems. It has the ability to detect and respond to stimuli. Neurons make up nervous tissue and have the ability to transmit electrical impulses. The nervous system consists of the central nervous system as well as the peripheral nervous system. The central nervous system is comprised of the brain and the spinal

The "Fight or Flight" response The flight or fight response‚ also called the "acute stress response" was first described by Walter Cannon in the 1920s as a theory that animals react to threats with a general discharge of the sympathetic nervous system.[4] [5] In response to acute stress‚ acetylcholine is released from preganglionic sympathetic nerves that innervate the chromaffin cells of the adrenal medulla. As a consequence‚ the chromaffin cells secrete the hormone epinephrine (adrenaline)

If they were ripped and torn‚ the reattachment would be extremely difficult. 4) The doctor had to trim the bone on each side of the

The human toxicity of 1-bromohexane includes; irritation to eyes and skin if contact occurs‚ irritation to lungs and respiratory system if inhaled‚ and skin inflammation along with itching or blistering. Some of the toxic effects that KPF6 has on humans are destruction of tissues in the membrane of the upper respiratory tract if inhaled‚ and burns on skin and eyes if contact occurs

An adolescent brain needs proper nutrition in order to develop and grow. Too little or too much nutrients will affect the nervous system and could possibly delay cognitive development. Under nutrition can cause delay in cognitive growth and development. If the brain does not have the adequate vitamins‚ minerals and micronutrients it does not have the ability to grow brain tissues and conduct nerve impulses correctly. This could lead to inappropriate behaviors and social adaption as well as decreased

is threatening. It then signals to our body how to react. Studies hall all revealed that before anger affects any part of our body‚ it has to affect our brain first. The brain is our internal alarm system. It signals to the rest of our body when we are happy‚ sad‚ angry‚ in pain‚ etc. this alarm system within our brain triggers the release of adrenaline which causes us to heighten our awareness and responsiveness. This causes glucose to gush through our blood stream and muscles giving us the ability
