what is the difference between voluntary and reflex reaction?

Answer 1

A voluntary reaction is one that when a sensory neuron feels something, say heat, it sends a signal to the spinal cord, then to the brain, the brain makes the conscious decision to remove your hand and send the signal to do so back to the hand muscles.

A reflex reaction is one that takes the sensory neuron's signal, takes it to the spinal cord to an interneuron and directly back to the muscle where it retracts without the brain even needing to take the time consuming decision process.

Answer 2

The signals processed by the CNS can result in two different types of action. They may be passed to the higher centres of the brain and result in a conscious act. This is a voluntary action.

But if the safety of the organism demands a very quick response, the signals may be passed directly, via a relay neurone, to a motor neurone for instant, unthinking action. This is a reflex action.

Answer 3

Muscle function is to produce force and cause motion, either locomotion or movement within internal organs. Much of muscle contraction occurs without conscious thought and is necessary for survival, like the contraction of the heart or peristalsis, which pushes food through the digestive system. Voluntary muscle contraction is used to move the body and can be finely controlled, such as movements of the finger or gross movements like the quadriceps muscle of the thigh.

A reflex action is an automatic (involuntary) neuromuscular action elicited by a defined stimulus.

Answer 4

voluntary reactions are controlled by the brain and reflex reactions by the spinal cords.

Answer 5

voluntary means you want it to move reflex reaction is movement to per-tect your self from any form of danger

Answer 6

watch the opening scene of "young frankenstein"

tells you exactly what you want to know, even though the part about blocking impulses using a clamp is silly :)
