Macula
The area of the retina with the highest density of photoreceptors. Due to this high "resolution," we see very sharply here. The diameter of the macula in humans is approximately 5 mm. The fovea centralis is located in the center of the macula.

Fovea centralis
The fovea centralis is located in the center of the macula and is the area of sharpest vision in birds and higher mammals. Its diameter in humans is approximately 1.5 mm. There are no rods in the fovea, only cones, which are interconnected to the ganglion cells in the central area of the fovea at a ratio of 1:1, resulting in very high "resolution."

Macular organs
Together with the semicircular canals, the macular organs form the vestibular system in the inner ear of vertebrates. They consist of two structures positioned perpendicular to each other, the saccule and the utricle. This alignment enables the macular organs to perceive linear accelerations of the body in space along all three spatial axes: up-down, front-back, left and right.
