The reflex arc allows sensory neurons to synapse in the spinal cord instead of the brain, allowing actions to occur relatively quickly by activating spinal motor neurons without needing to send signals through the brain.
For example, a person touching a hot stove would flinch before thinking about it, and protect tissues from further damage.

∙ 12y agoIt is useful as it means the signal does not have to go all the way to the brain and back to the muscle to react, instead it goes to the spinal column and back again which is slightly quicker meaning you can react more quickly e.g. if you touch something hot
btw this is why you react before your brain feels pain

∙ 10y agoA reflex arc is a neural pathway for an action reflex; ie it causes a certain reflex to occur in response to a certain stimulus. Reflex arcs allow the body to react to stimuli quickly, without waiting for the brain to make a decision.

How does effector relate to reflex arc?
An effector is at the end of a reflex arc as it is the muscle or gland that 'does' the reflex. What the effector does is the outcome of the reflex arc.
Reflexes are not carried to the brain?
A reflex arc does not pass through the brain. The somatic reflex arc and autonomic reflex arc are two types.
What controls reflex actions?
spinal cordautotomicspinal cord in the central nervous system controls reflex arc and reflex action.
How might damage to the spine affect a reflex arc?
Damage to the spine can affect the reflex arc by delaying the nerve pathway or making it so you are unable to move a muscle.
The sensory receptor sensory neuron motor neuron and effector involved in a reflex form a?
A reflex arc.
How hormones function in a reflex arc?
Hormones have nothing to do in reflex arc.
How does effector relate to reflex arc?

What is the pathway of reflex?
reflex arc
What are the effectors of a reflex arc?
Muscles and glands are the possible effectors of a reflex arc
Reflexes are not carried to the brain?
A reflex arc does not pass through the brain. The somatic reflex arc and autonomic reflex arc are two types.
What advantages are associated with the spinal cord and spinal nerve function below the level of consciousness?
You can have and you have the reflex arc situated spinal cord level. The function of the reflex arc can not be overemphasized. This reflex withdrawal from the harmful stimulus protects you to great extent. Secondly the spinal cord is well placed away from the brain. So that the arrangement of nerves in your brain becomes less complicated.
What type of neuron begins a reflex arc?
A sensory receptor is the type of neuron that begins a reflex arc.
What is the neural pathway of a single reflex called?
Reflex Arc
The neural pathway of a single reflex is called?
Reflex Arc
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.

What is the name for the path a reflex follows through the body?
