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.

What is the deference between an autonomic reflex and a visceral reflex?
An autonomic reflex involves responses that are controlled by the autonomic nervous system, which regulates involuntary bodily functions such as heart rate and digestion. A visceral reflex, on the other hand, involves responses that originate from organs in response to stimuli, such as the contraction of smooth muscle in the digestive tract in response to food. Both reflexes are important for maintaining homeostasis in the body.
What does the autonomic reflex involved?
The autonomic reflex is involved in controlling involuntary bodily functions such as heart rate, digestion, and respiratory rate. It helps maintain homeostasis by responding to changes in the internal and external environment without conscious effort.
Is a effector are skeletal muscles a somatic reflex or a autonomic reflex?
Skeletal muscles, which are effectors, are involved in somatic reflexes. Somatic reflexes involve voluntary control of skeletal muscles and are part of the somatic nervous system. Autonomic reflexes, on the other hand, involve the control of smooth muscle, cardiac muscle, and glands, and are part of the autonomic nervous system.
What is the order of a visceral reflex?
The order of a visceral reflex involves sensory receptors detecting a stimulus, which then sends signals via afferent neurons to the central nervous system. The central nervous system processes the information and sends signals through efferent neurons to the effector organs, resulting in a response to the stimulus.
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.
What is the deference between an autonomic reflex and a visceral reflex?
An autonomic reflex involves responses that are controlled by the autonomic nervous system, which regulates involuntary bodily functions such as heart rate and digestion. A visceral reflex, on the other hand, involves responses that originate from organs in response to stimuli, such as the contraction of smooth muscle in the digestive tract in response to food. Both reflexes are important for maintaining homeostasis in the body.
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 an ankle jerk reflex somatic or autonomic?
Ankle jerk is somatic. It is the reflex action, in which the afferent. connecting and the efferent neurons are involved. Autonomic nerves do not supply the striated muscles.
What does the autonomic reflex involved?
The autonomic reflex is involved in controlling involuntary bodily functions such as heart rate, digestion, and respiratory rate. It helps maintain homeostasis by responding to changes in the internal and external environment without conscious effort.
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.
What function does the medulla perform?
The medulla contains an autonomic reflex center involved in maintaining homeostasis of important visceral organs. Including the cardiac center which adjusts force and rate of heart contraction and the vasomotor center that regulates blood pressure by acting on smooth muscle in the walls of peripheral arterioles. Lastly, the respiratory center which controls the depth and rhythm of breathing.
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
Is a effector are skeletal muscles a somatic reflex or a autonomic reflex?
Skeletal muscles, which are effectors, are involved in somatic reflexes. Somatic reflexes involve voluntary control of skeletal muscles and are part of the somatic nervous system. Autonomic reflexes, on the other hand, involve the control of smooth muscle, cardiac muscle, and glands, and are part of the autonomic nervous system.
Flexor reflex somatic or autonomic?
it is a somatic reflex
