practical 3 - NEURO/SPINE/REFLEXES

what are the general of a reflex arc

1. sensory receptor (responds to stimulus by producing generator/receptor potential)

2. sensory neuron (axon conducts impulses from receptor —> integrating center)

3. integrating center (relays impulses from sensory to motor neurons)

4. motor neuron (axon conducts impulses from integrating center to effector)

5. effector (muscle/gland responds to motor impulses)
