activates the adrenal cortical system. The anterior pituitary gland begins the secrete adrenocorticotropic hormone directly into the bloodstream. When the ACTH reaches the adrenal cortex it stimulates the release of cortisol which increases the metabolism of proteins‚fats and carbohrdrates. Cortisol also increases blood sugar levels through gluconeogenesis. (1) Negative feedback Negative feedback is a process

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

This is why the babies sought their mothers when they left the room.

From the experiment‚ the blood glucose concentration for Patient A is 5.6 mmol/L(Refer to Table 1). The blood glucose level for Patient A is normal as 5.6mmol/L is in the normal range. Urine sample from Patient A was tested and it is shown that there was no glucose and sodium present. The results showed that Patient A is healthy and could act as a control in this investigation. Secondly‚ patient B is suspected to suffer from diabetes mellitus. The blood glucose concentration for Patient B is 111mmol/L
