what is the function of the conjunctiva in the eye
Conjunctiva The conjunctiva helps lubricate the eye by producing mucus and tears, although a smaller volume of tears than the lacrimal gland.[6] It also contributes to immune surveillance and helps to prevent the entrance of microbes into the eye.
Retina Once the image is spatially encoded by the centreâ€“surround structures, the signal is sent out along the optic nerve (via the axons of the ganglion cells) through the optic chiasm to the LGN (lateral geniculate nucleus). The exact function of the LGN is unknown at this time. The output of the LGN is then sent to the back of the brain. Specifically, the output of the LGN "radiates" out to the V1 primary visual cortex.
