Examples of pupil in the following topics:
-
- Horner's syndrome presents with drooping eyelids and pupil constriction, and is indicative of a problem in the sympathetic nervous system.
- Horner's syndrome, also known as oculosympathetic palsy, is a combination of drooping of the eyelid (ptosis) and constriction of the pupil (miosis) on one side of the face, accompanied by decreased sweating of the face on the same side .
- Loss of ciliospinal reflex: dilation of the pupil in response to pain applied to the neck, face, and upper trunk
- The pupil's light reflex is maintained as this is controlled via the parasympathetic nervous system.
- Sympathetic and parasympathetic innervation of the pupil.
-
- The oculomoter nerve (cranial nerve III) controls eye movement, such as constriction of the pupil and open eyelids.
- It enters the orbit via the superior orbital fissure and controls most of the eye's movements, including constriction of the pupil and maintaining an open eyelid by innervating the levator palpebrae superiors muscle.
- The Edinger-Westphal nucleus supplies parasympathetic fibers to the eye via the ciliary ganglion, and controls the pupillae muscle (affecting pupil constriction) and the ciliary muscle (affecting accommodation).
-
- As soon as the eye moves, it re-adjusts its exposure, both chemically and geometrically, by adjusting the iris (which regulates the size of the pupil).
- The pupil of the human eye is its aperture.
- Refraction in the cornea causes the effective aperture (the entrance pupil) to differ slightly from the physical pupil diameter.
- The entrance pupil is typically about 4 mm in diameter, although it can range from 2 mm (f/8.3) in a brightly lit place to 8 mm (f/2.1) in the dark.

- A teacher is a person who provides education for pupils and students.
- A teacher is a person who provides education for pupils and students.
- A teacher and young pupils at the British Museum Duveen Gallery.
-
- the choroid, which provides oxygen and nourishment to the eye and includes the pupil, iris, and lens; and
- The pigmented area around the pupil is the iris.
- Along with supplying a person's eye color, the iris is responsible for acting as the pupil's stop, or sphincter.
- Two layers of iris muscles contract or dilate the pupil to change the amount of light that enters the eye.
- Behind the pupil is the lens, which is similar in shape and function to a camera lens.
-
- In the middle of the iris is the pupil, the black dot that changes size.
- The fundus is on the opposite of the pupil, but inside the eye and can not be seen without special instruments.
- All of these are connected by the pupil.
- Whenever the eye moves, even just a little, it automatically readjusts the exposure by adjusting the iris, which regulates the size of the pupil.
- The pupil serves this function, and the iris is the aperture stop.
-
- In the middle of the iris is the pupil, which is the black dot that changes size.
- The fundus is on the opposite of the pupil, but inside the eye and cannot be seen without special instruments.
-
- Furthermore, critics claim, sometimes teachers focused more on new IWB technology than on what pupils should be learning.
- Finally, the focus on interactivity in IWB can lead to over-valuing relatively mundane activities, and sometimes could actually slow the pace of whole class learning as individual pupils take turns at the board during these activities.
-
- Dilates pupils and relaxes the ciliary muscle to the lens, allowing more light to enter the eye and far vision.
- Causes constriction of the pupil and contraction of the ciliary muscle to the lens, allowing for closer vision.
-
- Light passes through the center of the iris, the pupil, which actively adjusts its size to maintain a constant level of light entering the eye.
- In conditions of high ambient light, the iris contracts, reducing the size of the pupil.
- In conditions of low light, the iris relaxes and the pupil enlarges .
