IB Biology SL C3.1.7 Output through motor neurons
Practise recognising motor neuron output from the CNS to effectors, especially how nerves stimulate muscles during movement.
How this is tested
- identify that motor neurons carry impulses from the CNS to effectors
- link nerve impulses to stimulation of muscle contraction in movement questions
- distinguish motor neuron pathways from sensory neuron pathways in MCQs
