Q

What is the ciliary muscle?

A

muscle that varies the curvature of the lens and changes its refractive power

17
Q

What is the vitreous chamber?

A

chamber where light passes through from the lens to the retina

18
Q

What are bipolar cells in the eye?

A

nerve cells that synapse with rods and cones

19
Q

What is the optic nerve?

A

nerve that travels from each eye toward the occipital lobe where complex analysis of visual images occurs

20
Q

What is the optic disk?

A

point in the retina where many axons form ganglion cells that converge to form the optic nerve

21
Q
