Sensory neurones Study guides, Revision notes & Summaries

the document focuses on the nervous system, from its functions to explaining sympathetic and parasympathetic nervous system. the document also contains general structure and functions of the neurone. the documents also contains sensory, relay, motor neurones information. It also explains the knee-jerk reflex and the glial cells. The documents also has stages of action potential and comparison between myelinated and non-myelinated. the saltatory conduction is explained using diagram and stages in...

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...

AQA A level Biology - Topic 6 - survival and response questions and answers already passed What is a stimulus? A change in the environment of an organism What is a tactic response? Directional movement in response to a stimulus What is a kinetic response? Non directional random movement in response to a stimulus What is a positive and negative taxis? Positive taxis- organism moves towards stimulus Negative taxis - organism moves away from stimulus What Are receptors? Detect stimuli- can be c...
