what do sensory neurones do - Answer carry nervous impulses from receptors into the central nervous system (CNS) what do motor neurones do - Answer carry impulses from the CNS to the effector organs What do relay neurones do? - Answer relay neurones are intermediate neurones they recieve impulses from a sensory neurone and relay them to motor neurones what are dendrites - Answer carries nervous impulses towards a cell body what is an axon - Answer carry nervous impulses ...

What is homeostasis? The regulation of the conditions inside your body and cells to maintain a stable internal environment, in response to changes in both internal and external conditions Name three coordination centres The brain, the spinal cord and the pancreas What is negative feedback? When your body brings the level of something (e.g. water or temperature) back to normal if it becomes too high or too low What detects a stimulus? A receptor, e.g. skin receptors detec...

What is homeostasis? - Answer The process of maintaining a stable internal environment Why is homeostasis important? - Answer Because it is essential for the survival of cells What does the control system do? - Answer Keeps the conditions in your body steady What happens in the blood glucose level is too high? - Answer the control system decreases the level What happens in the blood glucose level is too low? - Answer the control system increases the level What does ...
