The external eye muscles are responsible for the movements of the eyes, i.e. changing the direction of gaze. They attach to different parts of the eyeball.
Humans have four straight and two oblique eye muscles. Their interaction is complex and thus able to perform all rotational movements of the eye in all directions.
Unlike the inner eye muscles, the outer eye muscles are skeletal muscles that are subject to voluntary control. The eyelids also have their own muscles that are responsible for their movement.
Anatomy of the human eye
Optic nerve (lat. Nervus opticus) in the eye
The optic nerve is responsible for ensuring that information from the retina reaches the brain. The concentrated bundle of millions of nerve fibers converts the light stimuli from the retina into impulses and sends them to ...
Inner eye shell
The inner shell forms the retina. It is used to receive light stimuli. The light impressions are transmitted to the brain via the optic nerve and processed there.
Blind spot (papilla)
The so-called blind spot is the point in the eye where the retina is interrupted and merges with the optic nerve. Since there are no light receptors at this point, ...
