PERIORBITAL MEMBRANE Meaning and
Definition
-
The periorbital membrane refers to a thin layer of tissue that surrounds and protects the orbit, which is the bony socket that houses the eyeball. It is primarily composed of connective tissue fibers and acts as a barrier that helps maintain the integrity and stability of the eye.
This membrane is located on the exterior surface of the eye, between the eyelid and the underlying tissues. It serves several crucial functions, including providing support and cushioning to the eye, as well as anchoring the muscles and ligaments responsible for eye movement and maintaining the position and shape of the eyeball.
In addition to its structural role, the periorbital membrane contains blood vessels and nerves that supply the eye and surrounding tissues with oxygen, nutrients, and sensory information. It acts as a conduit for sensory signals such as touch, temperature, and pressure, allowing individuals to perceive their environment and respond accordingly.
The periorbital membrane is also involved in regulating tear production and drainage. It houses the lacrimal gland, which produces tears, and various tear drainage ducts, helping to lubricate and cleanse the eye.
Overall, the periorbital membrane is an essential component of the eye's anatomy, providing protection, support, and sensory function to maintain healthy vision and eye function.

Etymology of PERIORBITAL MEMBRANE
The word "periorbital" is derived from the Latin word "peri-" meaning "around" and "orbis" meaning "circle" or "ring". It refers to the area surrounding the orbit or eye socket.
The word "membrane" comes from the Latin word "membrana" meaning "parchment" or "membrane". It refers to a thin, pliable sheet or layer of tissue that covers or lines a structure.
Therefore, "periorbital membrane" combines these two terms to describe the thin, flexible layer of tissue that surrounds the eye socket.
