Fovea Centralis An area of the retina that’s located directly behind the centre of the lens and has a very high concentration of cones, which makes this part of the eye responsible for great visual acuity. Cornea A transparent portion of the sclera (located at the front of the eye) that allows light to enter the eye and, in the process, refracts or bends the light rays so they can be focused on the cornea. Ciliary Muscle A ring of muscle behind the iris that’s attached to the lens by suspensory ligaments and is involved in changing the shape of the lens.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
