Differbetween
Reactions are voluntary responses whereas reflexes are involuntary or unintentional (and not subject to conscious control in most cases). Each type of response is initiated by a sensory stimulus that may be visual, audible, tactile, olfactory, or gustatory in nature.

What is an example of a reflex?
A few examples of reflex action are: When light acts as a stimulus, the pupil of the eye changes in size. Sudden jerky withdrawal of hand or leg when pricked by a pin. Coughing or sneezing, because of irritants in the nasal passages.
Where does a reflex travel to vs a reaction?
A reflex arc is a neural pathway that controls a reflex. In vertebrates, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This allows for faster reflex actions to occur by activating spinal motor neurons without the delay of routing signals through the brain.
What do you mean by reflex?
A reflex is an involuntary (say: in-VAHL-un-ter-ee), or automatic, action that your body does in response to something — without you even having to think about it.
What is the difference between reaction time and response time?
Reaction time is an internal metric and consists of assigning/reassigning and sending/archiving; whereas response time is an external metric measuring only the response to the customer.
What is an example of a Polysynaptic reflex?
An example of a polysynaptic reflex arc is seen when a person steps on a tack—in response, their body must pull that foot up while simultaneously transferring balance to the other leg.

What are 3 reflexes in humans?
Types of human reflexes
- Biceps reflex (C5, C6)
- Brachioradialis reflex (C5, C6, C7)
- Extensor digitorum reflex (C6, C7)
- Triceps reflex (C6, C7, C8)
- Patellar reflex or knee-jerk reflex (L2, L3, L4)
- Ankle jerk reflex (Achilles reflex) (S1, S2)
What will happen if we don't have reflex action?
If the reaction is exaggerated or absent, it may indicate a damage to the central nervous system. Most reflexes go completely unnoticed because they don't involve a visible and sudden movement. Body functions such as digestion or blood pressure, for example, are all regulated by reflexes.
What do good reflexes mean?
Brisk reflexes describe an instance where the muscles contract more strongly or more times than normal. If you have brisk reflexes, you might also have one or more of the following symptoms: gait (walking) problems. difficulty grabbing objects.
What are the types of reflex?
There are two types of reflex arcs:the autonomic reflex arc, affecting inner organs, and the somatic reflex arc, affecting muscles. When a reflex arc consists of only two neurons, one sensory neuron, and one motor neuron, it is defined as monosynaptic. Monosynaptic refers to the presence of a single chemical synapse.

What are the four types of reflexes?
In our discussion we will examine four major reflexes that are integrated within the spinal cord: the stretch reflex, the Golgi tendon reflex, the withdrawal reflex and the crossed extensor reflex.
