Reflex Action and Reflex Arc: Concepts, Solved Questions.
An integration center in the reflex arc is a neuropathway that creates a reflex action to activating neurons to skip the spinal cord and protect your brain. The nerve cells can be categorized by their connections, structure, and neurotransmitters.

So because we don’t have any interneurons in this what we call a simple reflex arc, let me write that here, there’s hardly any processing happening here. Once a signal comes in, a signal will go out, the muscle s will contract, and the knee jerk reflex will happen, the leg will extend.
The Reflex Arc Of The Biceps Femoris And Semimembranosus ( Flexors ) Stretch - 8) When activating the reflex arc of the Biceps femoris and Semimembranosus (flexors) stretch is the sent through sensory neurons to the dorsal side of the spinal cord where a motor signal travels down the alpha neuron leaving the ventral side of the spinal cord and signals the quadriceps femoris, rectus femoris.
Reflex actions. A reflex action is a protective, automatic and rapid response to a stimulus. It follows the same general sequence as a normal reaction but often it does not involve the brain.
A reflex action, also known as a reflex, is an involuntary and nearly instantaneous movement in response to a stimulus. When a person accidentally touches a hot object, they automatically jerk their hand away without thinking. A reflex does not require any thought input. The path taken by the nerve impulses in a reflex is called a reflex arc.
A reflex action is an automatic response to a stimulus. A reflex arc describes the pathway of an electrical impulse in response to a stimulus. Relay neurones are found in the spinal cord, connecting sensosy neurones to motor neurones. On the picture below, the stimulus is a drawing-pin sticking in the finger.
