How do autonomic nervous system reflex arcs work?
GaleEncyofNeuroDis
ANS reflex arcs are stimulated by input from sensory or visceral receptors. The signals are processed in the hypothalamus (or regions of the spinal cord) and target effector control is then regulated via myelinated preganglionic neurons

Which part of the nervous system is used to coordinate a reflex response?
A spinal reflex is a reflex that is centered in the spinal cord. The parts of the nervous system in one of these include the spinal cord as well as deep tendon nerves and sensory nerves.
How do visceral reflex arcs differ from somatic?
Visceral reflex arcs involve involuntary responses in internal organs, modulated by the autonomic nervous system. In contrast, somatic reflex arcs involve voluntary responses in skeletal muscles, controlled by the somatic nervous system.
Does the nervous system control your blinking and sneezing?
The medulla oblongata is responsible for regulating several basic functions of the autonomic nervous system, including respiration, cardiac function, vasodilation, and reflexes like vomiting, coughing, sneezing, and swallowing.
How is it possible for the GI tract to have complete reflex arcs without having to pass impulses through the central nervous system?

How is reflex handled in the nervous system?
Reflexes are rapid, automatic responses to a stimulus that help protect the body from harm. They are controlled by neural pathways called reflex arcs, which involve sensory neurons, interneurons, and motor neurons. Reflexes can be either innate (built-in) or learned through experience.
Is salivation an automatic reflex?
The withdrawal reflex is both a somatic and autonomic reflex (brain). Withdrawal from a painful stimulus is one test used in brain injury. Without the somatic connection to the autonomic brain areas, you'd have no withdrawal reflex at all when something interferes with that connection (such as brain injury or brain death).
Which component of a reflex arc is located entirely within the central nervous system?
The interneuron is the component of a reflex arc that is located entirely within the central nervous system. It receives sensory information from the sensory neuron and relays it to the motor neuron to initiate a response without the need for input from the brain.
Is PNS involved in reflex actions?
Yes, the peripheral nervous system (PNS) is involved in reflex actions. Reflex arcs allow sensory information to be processed in the spinal cord and produce motor responses without involving the brain. The PNS carries the sensory information to the spinal cord and the motor responses back to the muscles or glands.
What kind of reflex has only two neurons?
monsynaptic reflex arcs
What is reflex arcs?
Please restate this question for clarification...
Which reflex arcs contain no association neuron?
Simple reflex arcs, where a sensory neuron directly synapses with a motor neuron in the spinal cord, do not involve an association neuron. These reflex arcs allow for immediate and involuntary responses to stimuli without the need for processing in the brain. Examples include the knee-jerk reflex and withdrawal reflex.
Why are reflex arcs important?
to protect our body from harmful stuff.
