Ora serrata
Ora Serrata
The Ora Serrata (pronounced: /ˈɔːrə sɛˈrɑːtə/) is the serrated junction between the retina and the ciliary body. This junction marks the transition from the simple, non-photosensitive area of the retina to the complex, multi-layered, photosensitive region.
Etymology
The term "Ora Serrata" is derived from Latin, where "Ora" means 'edge' or 'boundary', and "Serrata" means 'serrated' or 'notched like a saw'. This term accurately describes the appearance and location of this anatomical feature.
Function
The Ora Serrata plays a crucial role in the eye's function. It is the part of the eye where the sensory retina ends, and the non-sensory retina begins. This transition is vital for the eye's ability to process light and create visual images.

- Retina: The light-sensitive layer of tissue at the back of the inner eye that translates light into nerve impulses.
- Ciliary Body: The part of the eye that produces aqueous humor, the fluid in the eye. It also contains the ciliary muscle, which changes the shape of the lens when your eyes focus on something.
- Eye: The organ of sight, in vertebrates typically one of a pair of spherical bodies contained in an orbit of the skull and in humans appearing externally as a dense, white, curved membrane, or sclera, surrounding a circular, colored portion, or iris, that is covered by a clear, curved membrane, or cornea, and in the center of which is an opening, or pupil, through which light passes to the retina.
