Ganglion cillare is a term used to describe a small cluster of nerve cell bodies called ciliary ganglion. It plays an important role in eye function and helps regulate the size of the pupils. The spelling of this term is pronounced as /ˈɡæŋɡliən sɪˈlɛəri/ using the International Phonetic Alphabet (IPA). The 'g' in 'ganglion' is silent, while the 'c' in 'cillare' is pronounced as /s/ sound. This spelling is important in medical fields where a clear and precise understanding of terminologies is essential.
Ganglion cillare refers to a specialized cluster of nerve cells or ganglion residing in the eye, specifically found in the ciliary body. The ciliary body is a structure located between the iris and the choroid, which plays a crucial role in controlling the shape of the lens and aiding in the process of accommodation for near and far vision.
The ganglion cillare consists of a collection of neuronal cell bodies that are responsible for receiving and processing visual information in the eye. These clusters of nerve cells are intricately connected with various parts of the eye, including the retina, optic nerve, and other structures involved in vision.
This ganglion is primarily responsible for adjusting the curvature of the lens to help focus incoming light onto the retina, ensuring clear vision at different distances. This process, known as accommodation, is essential for the eye's ability to adjust its focus from near objects to distant objects and vice versa.
The ganglion cillare receives and integrates signals from the brain and the retina to carry out its function effectively. It is coordinated by the autonomic nervous system, which regulates involuntary actions in the body, including those related to vision.
Overall, the ganglion cillare is a critical component of the eye's complex system, involved in providing clear and focused vision.
Ciliary g., lenticular or ophthalmic g., a small g. in the orbit between the optic nerve and the external rectus muscle, having three roots: a long root (sensory) from the nasociliaris, a short root (motor) from the inferior ramus of the culomotor, and a sympathetic root; it gives origin to the short ciliary nerves which supply the coats of the eyeball, the ciliary muscles, and the iris.

The term "ganglion cillare" is derived from two different languages: Latin and Greek.
The word "ganglion" comes from the Latin word "ganglion" (meaning a knot, bundle), which in turn is derived from the Greek word "γάγγλιον" (ganglion) with the same meaning. The term was used in ancient medicine to describe a small swelling or knot-like structure.
The word "cillare" is derived from the Latin word "cilium" (meaning eyelid), which again has Greek origins. The Greek word for eyelid is "κίλιον" (kilion).
Therefore, "ganglion cillare" can be translated as "knot-like structure of the eyelid" or "eyelid knot". This term is often used in the field of ophthalmology to refer to a ganglion cyst located on the eyelid.
