Which nucleus is related to ciliary ganglion?
The parasympathetic root branches from the inferior division of the oculomotor nerve and carries the preganglionic parasympathetic axons from the Edinger-Westphal nucleus to the ciliary ganglion.
What nerve innervates the ciliary ganglion?
The neurons of the ciliary ganglion receive preganglionic autonomic fibers of the oculomotor nerves. The neurons control the intrinsic eye muscles, which change pupil diameter, to adjust the amount of light that enters the eye. These muscles also change the lens’ shape, focusing images on the retina.
What is the function of the ciliary ganglion?
Nerves from the ciliary ganglion innervate the muscles that constrict the pupil, a hole in the iris that lets light enter the eye. Other fibers from the ciliary ganglia go to muscles that control the shape of the lens in the eye.
What is ophthalmic nerve?
The ophthalmic nerve is the first branch of the trigeminal nerve, which is also known as the fifth cranial nerve. The ophthalmic nerve supplies sensory innervation to the structures of the eye, including the cornea, ciliary body, lacrimal gland, and conjunctiva.
What Innervates nasociliary nerve?
The branches of the nasociliary nerve provide sensory innervation to structures surrounding the eye such as the cornea, eyelids, conjunctiva, ethmoid air cells and mucosa of the nasal cavity.
What are the sympathetic ganglia?
The sympathetic ganglia, or paravertebral ganglia are autonomic ganglia, of the sympathetic nervous system. Ganglia are 20,000 to 30,000 afferent and efferent nerve cell bodies that run along on either side of the spinal cord. The cell bodies create long sympathetic chains that are on either side of the spinal cord.
What is cranial nerve ganglia?
Cranial Nerve Ganglion (not all CN have) is analogous to the dorsal root ganglion, except that it is associated with a cranial nerve, instead of a spinal nerve (associated with the spinal cord). The roots of cranial nerves are within the skull, whereas the ganglia are outside the skull.
What does the nasociliary nerve supply?
The nasociliary nerve provides sensory perception to the cornea, eyelids, conjunctiva, and cells and mucous membranes of the nasal cavity. Its function is exclusively sensory, with no motor function. The ophthalmic nerve, of which the nasociliary nerve branches, networks with the eye’s motor nerves.
Which gland receives parasympathetic innervation from the glossopharyngeal nerve CN IX )?
The parotid gland
The parotid gland receives parasympathetic innervation via fibers of the glossopharyngeal nerve (CN IX) and auriculotemporal nerve. The preganglionic fibers, carried by the glossopharyngeal nerve, synapse in the otic ganglion.
