Visceral Effector Organs
When you happen to step on a nail, your foot will automatically withdraw without you commanding it. This is a result of the action of the effector organ and similar components. It is called a reflex action because the pain receptors in your foot reacted out of their own volition to initiate the action. You did not “think” about withdrawing your foot.
What is the effector organ?
The effector organ is one of the five basic components of a reflex arc. The other four components are motor neuron, the sensory receptor, the sensory neuron, and the interneurons. The motor neuron organizes the action. The sensory receptor recognizes the stimulus and sends it to the sensory neuron. The interneurons, on the other hand, lie between two neurons and communicate with them.
What is a reflex arc?
The reflex arc is the simplest way for the central nervous system to receive and react to a stimulus. When a stimulus is applied, it is conducted to the central nervous system. This will allow the muscle to contract and bring the injured body part away from the painful stimulus. This response is automatic and does not require a conscious effort from the person.
What are visceral effector organs?
These are effector organs influenced by involuntary effector muscles, which can only mobilize when specific nerve impulses are conducted to the smooth muscles. Nerve impulses are important to elicit the appropriate response to that particular stimulus. The effector organ would only respond when neural activity has taken place.
The visceral effector organs are important components for normal body function. Reflex arcs are the basis of reaction for effector organs. Learning something about the processes that occur in your nervous system will help a lot in understanding why we react the way we do to certain occurrences.
