ARTERIA EPISCLERALIS Meaning and
Definition
-
Arteria episcleralis is a term primarily used in the field of medicine, specifically in ophthalmology, to refer to a specific blood vessel located in the episclera region of the eye. The episclera is a thin tissue layer located between the conjunctiva and the sclera, which is the tough, white outer layer of the eyeball.
The arteria episcleralis, also known as the episcleral artery, is a small branch of the anterior ciliary artery. It arises from the external carotid artery and supplies blood to the episclera, sclera, and conjunctiva of the eye. This blood vessel is responsible for delivering oxygen and nutrients to these tissues, ensuring their proper function and health. It also plays a role in regulating the temperature of the eye.
In certain ocular conditions such as anterior uveitis or scleritis, the arteria episcleralis may become dilated, leading to redness and increased blood flow in the affected area. This condition is called episcleritis and can cause discomfort, irritation, and visible redness on the surface of the eye.
Understanding the anatomy and function of the arteria episcleralis is important for ophthalmologists and eye care professionals as it can help in diagnosing and managing various eye diseases and conditions that may affect the episcleral blood vessels.

Etymology of ARTERIA EPISCLERALIS
The word "arteria episcleralis" is a Latin term that can be broken down into two parts:
1. Arteria: In Latin, "arteria" means artery. This term is derived from the Greek word "ἀρτηρία" (arteria), which refers to the windpipe or artery. The Greek word is believed to have originated from the word "ἀήρ" (aér), meaning air or wind, as early anatomists considered arteries to be hollow tubes responsible for carrying air or vital spirit within the body.
2. Episcleralis: The term "episcleralis" is a Latin adjective derived from the noun "episclera", which is a medical term in anatomy referring to a thin layer of tissue located between the conjunctiva and the white of the eye.
