| With the head erect, the macula in each utricle is oriented horizontally, and in the saccule vertically. |
| The macula densa and JG cells are jointly called the juxtaglomerular apparatus. |
| The central retina, or macula, and the centermost macula, or fovea, exhibit structural and cellular specializations for fine central acuity. |
| Degeneration of the macula causes blurred central vision or a blind spot in the center of your visual field. |
| The focus is on a 3-millimeter-wide yellow spot, called the macula lutea, toward the back and center of the eye. |
| The macula serves to facilitate central vision and allows for high-resolution visual acuity. |
