IB Biology SL C3.1.6 Input through sensory neurons
Practise tracing sensory input from receptors to the CNS, including how mouth receptors detect heat, chemicals or texture in food.
How this is tested
- identify sensory neuron pathways from receptors to the central nervous system
- outline how thermoreceptors, chemoreceptors or mechanoreceptors detect stimuli
- distinguish sensory input from motor output in receptor-effector pathways
