Sensory neurones - Study guides, Class notes & Summaries

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

AQA GCSE Biology Paper 2 Graded A+ What is homeostasis? ️The maintenance of a constant internal environment. What is a stimulus? ️A change in your environment than requires a response. e.g Light, sound, touch, pressure, pain, chemical or temperature. What do the receptors do? ️Detect the stimulus or change in environment. What happens after the receptors? ️Receptors send messages to the CNS via the sensory neurone. What makes up the central nervous system? ️The brain or spi...

Role of neurones - Answer To transmit electrical impulses rapidly around the body to allow the organism to respond to changes in internal and external environment Parts of a general neurone - Answer Cell body, Dendron, axon, Role of the cell body - Answer To produce neurotransmitters Structure of cell body - Answer Nucleus, cytoplasm, lots of endoplasmic reticulum, mitochondria Function of dendrons - Answer To transmit electrical impulses towards the cell body Function o...

AQA GCSE Biology Topic 5 Homeostatis Homeostasis The maintenance of a constant internal state in a changing environment Why is homeostasis important? Homeostasis is important because it is essential for the survival of cells and enzymes Automatic control systems are made up of Receptors, coordination centres, effectors negative feedback a mechanism of response in which a stimulus initiates reactions that reduce the stimulus Receptor Detects change Coordination centre Receives an...
