which cranial nerves are part of the autonomic nervous system?
311156
The cranial preganglionic neurons project to the cranial nerves with autonomic activity: III, VII, IX, and X. Unlike the sympathetic nervous system, the parasympathetic postganglionic neurons are located near to end-organ systems, resulting in long preganglionic axons and relatively short postganglionic axons.

The peripheral nervous system is itself classified into two systems: the somatic nervous system and the autonomic nervous system. Each system contains afferent and efferent components. The afferent arm consists of sensory (or afferent) neurons running from receptors for stimuli to the CNS.

The Cranial Sympathetics—The cranial sympathetics include sympathetic efferent fibers in the oculomotor, facial, glossopharyngeal and vagus nerves, as well as sympathetic afferent in the last three nerves.

The autonomic nervous system is the part of the nervous system that supplies the internal organs, including the blood vessels, stomach, intestine, liver, kidneys, bladder, genitals, lungs, pupils, heart, and sweat, salivary, and digestive glands. The autonomic nervous system has two main divisions: Sympathetic.

The twelve cranial nerves, in order from I to XII are: olfactory nerve, optic nerve, oculomotor nerve, trochlear nerve, trigeminal nerve, abducens nerve, facial nerve, vestibulocochlear nerve, glossopharengeal nerve, vagus nerve, spinal accessory nerve, and hypoglossal nerve.

The four cranial nerves involved in vision and movement of the eyes are the optic (II) nerve, oculomotor (III) nerve, trochlear (IV) nerve and the abducen (VI) nerve. The optic nerve is the sensory nerve for vision. It transmits information from the eyes to the brain.

Introduction. The autonomic nervous system is a component of the peripheral nervous system that regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, and sexual arousal.

The autonomic nervous system is a division of peripheral nervous system that is not under voluntary control. It is often regarded as a self-regulating system. It controls the functions of internal body organs such as stomach, heart, lungs, urinary bladder, etc.

Mixed cranial nerves are the cranial nerves that contain sensory and motor nerve fibers. There are four of such nerves in our peripheral nervous system; ... Facial nerve (CN VII) Glossopharyngeal nerve (CN IX) Vagus nerve (CN X)
1319529
The effectors of the autonomic nervous system are cardiac muscle, smooth muscle, and glands.

- The peripheral nervous system includes the cranial nerves (connected to brain innervate the head), spinal nerves (connected to spinal cord innervates the rest of the body), and ganglia (collections of neuron cell bodies in the PNS). ... Inside the ganglia are the cell bodies of the sensory neurons.

The peripheral nervous system is divided into the somatic nervous system and the autonomic nervous system.
233587
the parasympathetic and sympathetic nervous systems are subdivisions of the autonomic nervous system. ... the parasympathetic division is also called the craniosacral division since the preganglionic neurons originate in the brain and sacral region of the spinal cord.

The autonomic nervous system regulates a variety of body process that takes place without conscious effort. The autonomic system is the part of the peripheral nervous system that is responsible for regulating involuntary body functions, such as heartbeat, blood flow, breathing, and digestion.

Structure. The peripheral nervous system is itself classified into two systems: the somatic nervous system and the autonomic nervous system. Each system contains afferent and efferent components. The afferent arm consists of sensory (or afferent) neurons running from receptors for stimuli to the CNS.

In the somatic nervous system, the cranial nerves are part of the PNS with the exception of the optic nerve (cranial nerve II), along with the retina. The second cranial nerve is not a true peripheral nerve but a tract of the diencephalon. Cranial nerve ganglia originated in the CNS.
