What organs are involved in an autonomic visceral reflex?
An autonomic visceral reflex typically involves the autonomic nervous system, which includes the sympathetic and parasympathetic divisions. Key organs involved include the brain (particularly the hypothalamus and brainstem), spinal cord, and various visceral organs such as the heart, lungs, gastrointestinal tract, and glands. Sensory receptors detect changes in the internal environment, sending signals through afferent pathways to the central nervous system, which then coordinates an appropriate response via efferent pathways to the target organs.
Is a gag reflex considered an autonomic reflex?
Yes, the gag reflex is considered an autonomic reflex. It is a protective mechanism that helps prevent choking by triggering the muscles in the throat to contract involuntarily in response to stimuli at the back of the throat.
Where does occur the the autonomic reflex centers?
The autonomic reflex centers are located in the brainstem and spinal cord. The brainstem houses important autonomic centers such as the medulla oblongata and pons, which regulate functions like heart rate and respiration. The spinal cord contains reflex arcs that control activities like urination and defecation.
Is nausea a autonomic reflex?
Yes. You are right. Most probably nausea is mediated through autonomic nervous system.
Is sleeping an autonomic or somatic reflex?
Sleeping is not a reflex but a complex process controlled by the brain. It involves both autonomic and somatic functions, but it is not considered a reflex as it is more of a regulated state of consciousness rather than a simple automatic response to a specific stimulus.

How do visceral reflex arcs differ from somatic?
An autonomic reflex arc is similar to the somatic kind, but differs principally in the motor output side. The sensory side is similar in that a transducer sends a signal via a nerve fiber into the CNS. As with the somatic arc, this sensory fiber is associated with a pseudo-unipolar neuron in a craniospinal ganglion, usually one of the dorsal root ganglia. In the autonomic arc, the sensory transducer is often located in or associated with visceral organs.
Is a patellar reflex autonomic?
no
Does visceral reflex arcs have two sensory neurons?
No, it has 2 visceral motor neurons. A visceral reflex has a receptor, a sensory neuron, a processing center, and 2 visceral motor neurons.
What reflexes are classified as autonomic reflexes?
The ciliospinal reflex and the pupillary light reflex are classified as autonomic reflexes.
How do autonomic nervous system reflex arcs work?
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
Flexor reflex somatic or autonomic?
it is a somatic reflex
What reflex regulates the activity of smooth muscle?
autonomic reflex
Examples of visceral reflexes?
An example of a visceral reflex would be the things your stomach has to do to digest food. There are sensory receptors that get stimulated when food is present and they tell other cells to get on with the work of digestion by a visceral (internal organ) reflex. Your digestive system has so many of these that the network involved with this is sometimes called the second brain.
Is the corneal reflex a somatic reflex or an autonomic reflex?
This particular reflex is autonomic as the affected muscle, constrictor pupillae muscle, is a smooth muscle and not under conscious control. Typically if you can consciously contract the muscle, any reflex associated with that muscle is somatic in nature.
Is a pupil autonomic reflex?
yes
Is a gag reflex a somatic reflex?
No, a somatic reflex are the reflexes of the skeletal muscle movements. The gag reflex is considered to be an autonomic reflex.
