The pathway that an impulse travels from your foot back to your leg is an example of a reflex arc. A reflex arc includes a sensory receptor (in this case, a receptor in your toe), sensory neuron, motor neuron, and effector (leg muscle). Some reflex arcs include interneurons. In other reflex arcs, a sensory neuron communicates directly with a motor neuron.
A reflex action is an action that happens almost instantly without conscious thought. Grasp a very hot handle of a saucepan on the stove, and you immediately release the handle to avoid further burning by reflex action.
Many authors refer to the CNS portion of the reflex arc as the integration center.In regards to a monosynaptic reflex arc, the synapse is the only portion of the integration center.Polysynaptic reflex arcs, have multiple synapses and interneuron(s).
The reflex arc is the nerve pathway that the signal follows. For example, the knee jerk reflex arc has a stimulus going to an interneuron in the spine and a motor neuron completes the arc by causing the knee to jerk. A reflex is just the action itself.
The withdrawal reflex is both a somatic and autonomic reflex (brain). Withdrawal from a painful stimulus is one test used in brain injury. Without the somatic connection to the autonomic brain areas, you'd have no withdrawal reflex at all when something interferes with that connection (such as brain injury or brain death).

Reflexes are uncontrollable movements that happen almost instantly in response to a stimuli. A reflex arc, a neuronal circuit that controls reflexes, is where reflex activities takes place.
ANS reflex arcs are stimulated by input from sensory or visceral receptors. The signals are processed in the hypothalamus (or regions of the spinal cord) and target effector control is then regulated via myelinated preganglionic neurons
The patellar reflex is an example of a 2-neuron reflex arc. It has 1 sensory neuron and 1 motor neuron. It does not contain an association neuron and so is considered the most simple reflex in humans.
A reflex action is an action that happens almost instantly without conscious thought. Grasp a very hot handle of a saucepan on the stove, and you immediately release the handle to avoid further burning by reflex action.
No, it has 2 visceral motor neurons. A visceral reflex has a receptor, a sensory neuron, a processing center, and 2 visceral motor neurons.
