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.

∙ 12y agoIf you see a ball coming straight on your face, what will you do (maybe without thinking).. I guess the only thing that will automatically come in your mind is to Dodge the ball. But what if it hits your face? Your face will just become red. To summarize:
Dodging - reflex
Face becoming red - reaction

∙ 11y agosometimes the involuntary response produced by central nervous system(CNS) is very quick. such a response is called reflex action. The pathway followed by the nerve impulses for producing reflex action, is called reflex arc

What occurs during the reflex arc.?
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.
How and why do reflex arcs occur?
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.
Which component of a reflex arc is located entirely within the central nervous system?
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).
What are two example of reflex actions and their importance?
The Pupillary Light Reflex and the Corneal Reflex (or Blink Reflex) are two important reflexes because the Light Reflex prevents damage to eye compopents related to over exposure to light and also helps the eye to accommodate visually, when there is less light; The Blink Reflex prevents objects from entering the eye and lubricates the eye. Also, breathing and heart beat are thought to be reflex actions.
What action which does not require thinking?
Reflex actions do not require thinking, nor do the actions of involuntary muscles.
What kind of reflex has only two neurons?
monsynaptic reflex arcs
What kind of reflex uses just two neurons?
monosynaptic reflex arcs
What is reflex arcs?
Please restate this question for clarification...
Why are reflex arcs important?
to protect our body from harmful stuff.
Why don't fish have reflex actions?
Fish do have reflex actions.

Is reflex action and reflex arcs are same?
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.
How do autonomic nervous system reflex arcs work?
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
Which reflex arcs contain no association neuron?
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.
Which actions are not controlled by the brain?
Reflex actions are not controlled by the brain.
How and why do reflex arcs occur?
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.
What controls reflex actions?
spinal cordautotomicspinal cord in the central nervous system controls reflex arc and reflex action.
