Reflex Arc Components. Hitting this receptor stimulates it which causes it to send a nerve impulse along a sensory neuron to the spinal cord. A reflex action often involves a very. A Florida man and his grandson couldnt believe their eyes when they reeled in more than just some scrap metal and bottle caps during a magnet fishing weekend trip. Sensory neuron sends electrical impulses to a relay neuron which is located in the spinal cord of the CNS. It is conveniently shaped like an arc travelling to the spinal cord and back again.
Thereof how do reflexes work.
This pathway taken by nerve impulses to elicit a response is known as a reflex arc. A reflex arc is the name we give to the pathway of neurones from detecting the stimulus to initiating a response. Receptors sensory neurons interneurons motor neurons and muscles. Going back to our example about touching a hot tray this is first detected by thermoreceptors in the skin that detect heat changes thermo heat. The sensory neurons pick up signals from the sensory organ and send them through other neurons which are interconnected. Located in the brainstem and pons.

For example a simple reflex arc happens if we accidentally touch something hot. This results to a quicker time-to-response as the thinking process of the brain may be relatively time consuming. This process happens so fast that the response occurs before the message reaches the brain. The sensory neurons pick up signals from the sensory organ and send them through other neurons which are interconnected. Most reflex arcs have five main components.

Reflex arcs Receptor in the skin detects a stimulus the change in temperature. Hitting this receptor stimulates it which causes it to send a nerve impulse along a sensory neuron to the spinal cord. Reflex arc neurological and sensory mechanism that controls a reflex an immediate response to a particular stimulus. Nerve fibers located in the upper airways. In a reflex action the signals do not route to the brain instead it is directed into the synapse in the spinal cord hence the reaction is almost instantaneous.
