Which term describes the pigmented cell layer just outside the neurosensory retina that nourishes retinal visual cells and is firmly attached to the underlying choroid and overlying retinal visual cells?

The retinal pigment epithelium is the pigmented cell layer that sits between the neurosensory retina and the choroid. It nourishes the photoreceptors by transporting nutrients from the choroid, helps recycle visual pigments, and phagocytoses shed photoreceptor outer segments. It is tightly bound to Bruch’s membrane and the underlying choroid, while also lying against the outer part of the retina, providing a firm attachment to both structures. Its pigment also helps absorb excess light to reduce scatter. The other structures—vitreous (the gel filling the back of the eye), aqueous (the fluid in the anterior segment), and the optic nerve (which carries signals to the brain)—do not match this description.
