IB Biology SL C3.1.9 Pain reflex arcs
Practise labelling and explaining pain reflex arcs, including receptors, sensory neurons, interneurons, motor neurons and skeletal muscle effectors.
How this is tested
- identify receptors and skeletal muscle effectors in pain reflex arc MCQs
- label sensory neurons and interneurons on reflex arc diagrams
- explain impulse direction through receptor, spinal cord and effector pathways
