Spinal Reflex Flashcards
1
Q
Five components / pathway of spinal reflexs
A
1.Receptors (transduces mechanical energy into electrical energy)
2. Sensory neuron (afferent neuron) transmit the impulse through the peripheral nerve to the CNS
3. Control/intervention centre - inter neuron (takes signal and sends it to lower motor neuron)
4. Efferent (motor) neuron
5.Effector e.g. muscle of the hand

A
A subconscious stimulus response mechanism
Is a neural wiring of the single reflex and involves five steps
