While pupillary size in principle is controlled both by the sympathetic and the parasympathic nervous system, the typical closure of the pupil after illumination (i.e. the pupillary light reflex) is mediated by the parasympathetic innervation of the constrictor muscle of the pupil.

∙ 11y agoThe pupillary light reflex regulates the intensity of light entering the eye at any time.
The consensual response (equal reactions illicited on both sides of the body) observed prevents eye damage when exposed to intense light, specifically damage to the photoreceptor cells - cones and rods. This also enables more light to enter the eye so we are able to see in the dark.

Pupillary light reflex somatic or autonomic?
autonomic
Is the pupillary light reflex contralateral or ipsilateral?
The patellar reflex is ipsilateral. If the stimulus is applied to left knee cap, the left knee responds. On the other hand, if the right knee were to respond to a left knee stimulus, the response would be considered contralateral.
Reflex constriction of the pupils when viewing close objects?
Type your answer here... Constriction of the pupils is inability to adapt to changing light.
What is a accommodation pupillary reflex?
Adjustment of the focal length of the lens of the eye, to accomodate the various light rays from various distances.
What are two example of reflex actions and their importance?
The Pupillary Light Reflex and the Corneal Reflex (or Blink Reflex) are two important reflexes because the Light Reflex prevents damage to eye compopents related to over exposure to light and also helps the eye to accommodate visually, when there is less light; The Blink Reflex prevents objects from entering the eye and lubricates the eye. Also, breathing and heart beat are thought to be reflex actions.
Is the pupillary light reflex autonomic and somatic?
Pupillary light reflex is autonomic.
The pupillary light reflex is control by what autonomic nervous system?
pupillary light reflex is controlled by parasympathetic branch of Autonomous nervous system
What is photopupillary reflex?
Photopupillary reflex is pupillary constriction in response to light.
What is the receptor in pupillary reflex and the effector do both change simultaneously in pupillary reflex?
The receptor is the retina of the eye; smooth muscle of the iris is the effector. They both change simultaneously because the pupillary light reflex is contralateral.
Pupillary light reflex somatic or autonomic?
autonomic
Is pupillary light reflex a monosynaptic or polysynaptic reflex?
It is Polysynaptic
What has the author Sally-Ann E Mortlock written?
Sally-Ann E. Mortlock has written: 'Role of peripheral sympathetic activity in the human pupillary light reflex'
How does the patella reflex differ from the pupillary reflex?
The two are different because of what triggers the reflex. While the patella is triggered through the sense of touch, the pupillary is triggered through light.
What reflexes are classified as autonomic reflexes?
The ciliospinal reflex and the pupillary light reflex are classified as autonomic reflexes.
Name the division of autonomic nervous system responsible for pupillary light reflex?
The division of autonomic nervous system responsible for pupillary light reflex is the parasympathetic system. This is what causes the pupils to close down or open up in response to lighting conditions.
Is the pupillary light reflex contralateral or ipsilateral?
The patellar reflex is ipsilateral. If the stimulus is applied to left knee cap, the left knee responds. On the other hand, if the right knee were to respond to a left knee stimulus, the response would be considered contralateral.
What is papillary reflex?
You probably mean the pupillary reflex. It is the reflex responsible for your pupils constricting (becoming smaller) when exposed to light and dilating (becoming bigger) when you walk into a dark room.
