Final answer:
The axons of retinal ganglion cells join together to form the optic nerve, which carries visual information from the retina to the brain. The optic disc is where these axons leave the eye, creating a blind spot in our visual field.
Step-by-step explanation:
The axons of retinal ganglion cells (RGCs) join together to form the optic nerve. The optic nerve carries visual information from the retina to the brain. These axons leave the eye at the optic disc and pass through the retina, creating a blind spot in our visual field. The ganglion cells in the retina receive input from bipolar cells that connect to the photoreceptor cells.
