What is the receptor in pupillary reflex and the effector do both change simultaneously in pupillary reflex?
The receptor in the pupillary reflex is the optic nerve, which senses changes in light intensity. The effector is the circular and radial muscles of the iris, which control the size of the pupil. In the pupillary reflex, both the receptor and the effector work together to adjust the size of the pupil to regulate the amount of light entering the eye.
Is pupillary light reflex a monosynaptic or polysynaptic reflex?
The pupillary light reflex is a polysynaptic reflex. When light is sensed by the retina, a signal is sent via the optic nerve to the pretectal nuclei in the midbrain, which then sends signals to both the parasympathetic and sympathetic pathways controlling the muscles of the iris to constrict or dilate the pupil appropriately.
How do you spot someone on ecstasy?
You just have to look at the person's pupils; they'll be WIDE open and in general, exposure to bright light will not have any effect on the reflex of the iris to shrink.
Why is the iris reflex needed?
The iris reflex controls the amount of light entering the eye by adjusting the size of the pupil. This helps to regulate the amount of light that reaches the retina, ensuring optimal visibility in different lighting conditions. The reflex also protects the eye from bright light by constricting the pupil and reduces strain in dim lighting by dilating the pupil.

Retina- light image is focused on the retina, and it contains the photosensitive receptor cells Pupil- the opening of the eye. The size of the opening is regulated by the iris Iris- pigmented part of the eye (gives people their eye color). The iris is composed of smooth muscle and controlled by reflex.
What is the Colored part of your eye?
