• Somatic reflexes are the rapid, predictable, and automatic responses of skeletal muscle to changes in stimuli.
• A reflex arc is the pathway followed by the nerve impulse producing the reflex.
• Reflex arcs include:
• Sensory receptor
• Sensory neurons
• Integrating center
• Motor neuron
• Effector
• A monosynaptic reflex arc has a single synapse between the sensory and motor neuron.
• A polysynaptic reflex arc includes one or more association neurons relaying messages to other association neurons or motor neurons.
• An ipsilateral reflex is one that has the sensory neuron entering and the motor neuron exiting on the same side of the integrating center.
• In contrast, a contralateral reflex arc has a sensory neuron entering on one side and motor neurons exiting on the other.
• An intersegmental reflex arc has the signal of a single sensory neuron activating several motor neurons via the association neurons in several segments of the spinal cord.
