*Automatic responses coordinated within spinal cord. *Through interconnected sensory neurons, motor neurons, and interneurons. *Produce simple and complex reflexes |
Reflexes |
|
|
*Neural Reflexes Rapid, automatic responses to specific stimuli
|
Neural Reflexes |
|
|
*Reflex arc: Generally opposes original stimulus (negative feedback) |

*Five Steps in a Neural Reflex Step 1: Arrival of stimulus, activation of receptor Physical or chemical changes Step 2: Activation of sensory neuron Graded depolarization |

Four Classifications of Reflexes By early development By type of motor response By complexity of neural circuit By site of information processing |
Four Classifications of Reflexes |

|
1. Development How reflex was developed Innate reflexes: Basic neural reflexes Formed before birth Acquired reflexes: Rapid, automatic |
Reflexes: 1: Development How reflex was developed |
