The spelling of the word "corona ciliaris" can be explained using the International Phonetic Alphabet (IPA). "Corona" is pronounced as /kəˈroʊnə/, with the primary stress on the second syllable. "Ciliaris" is pronounced as /sɪˈleɪrɪs/, with the primary stress on the second syllable as well. The combination of the two words refers to the ciliary body of the eye, a structure that produces aqueous humour and is located near the iris. Accurate spelling and pronunciation of medical terms is crucial in effective communication between healthcare professionals.
Corona ciliaris refers to the structure located at the junction of the iris and ciliary body in the eye. It is a part of the anterior uvea, the middle layer of the eye, and plays a crucial role in the production and regulation of aqueous humor, a clear fluid that nourishes the frontal structures of the eye.
The corona ciliaris is composed of multiple ridges, called ciliary processes, which extend from the ciliary body towards the iris. These processes contain numerous blood vessels and specialized cells called ciliary epithelium. The ciliary epithelium consists of two layers: an outer pigmented layer and an inner non-pigmented layer.
The corona ciliaris is responsible for the production of aqueous humor through a process called active secretion. It actively transports ions, nutrients, and water across its epithelial layers, resulting in the formation of aqueous humor. This fluid then flows from the posterior chamber of the eye, between the iris and the lens, and into the anterior chamber.
Moreover, the corona ciliaris is involved in regulating the amount of aqueous humor in the eye. It is capable of altering the rate of active secretion based on various factors, such as intraocular pressure and neural signals, helping to maintain the optimal fluid balance in the eye.
Overall, the corona ciliaris is a vital anatomical structure in the eye responsible for the production and regulation of aqueous humor, thereby playing a pivotal role in maintaining the health and normal functioning of the eye.

The word "corona ciliaris" is a Latin term that can be broken down into two parts: "corona" and "ciliaris".
The term "corona" in Latin means "crown" or "garland". It is derived from the ancient Greek word "korone", which also means "garland" or "crown". This word was used to refer to a circular or crown-like object, often used as an adornment or symbol of prestige.
The term "ciliaris" in Latin is derived from the word "cilia", which refers to the eyelashes. The word "cilia" also comes from the Latin term "cilium", meaning "eyelid" or "eyelash".
Therefore, "corona ciliaris" can be translated as "ciliary crown" or "crown of eyelashes".
