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.
What part of in pupil reflex for stimulus?
The stimulus in the pupil reflex would be light
Pupillary light reflex somatic or autonomic?
autonomic
Is the pupillary light reflex sympathetic?
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.
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.
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.
What route does the reflex arc travel when the pupil changes with variations in light intensity?
The pupillary light reflex arc begins in the retina. Considerable evidence exists that the visual cells of the retina, that is, the rods and cones, also serve as light receptors controlling pupillomotor activity. [ Fibers originating from the nasal neuroreceptor cells decussate in the optic chiasm to the opposite optic tract, whereas the temporal fibers continue in the homolateral optic tract
Is the pupillary light reflex autonomic and somatic?
Pupillary light reflex is autonomic.
Is pupillary light reflex a monosynaptic or polysynaptic reflex?
It is Polysynaptic
Is the pupil a reflex or voluntary?
Pupils reacts to light, narrowing in bright light and widening in poor light - so is a reflex action.
What is photopupillary reflex?
Photopupillary reflex is pupillary constriction in response to light.

The stimulus in the pupil reflex would be light
how to get reflex green light instantly?
Reflex sux it takes alot of my Roblox time booo
Is shutting of eyelids on exposure to bright light a simple or conditioned reflex?
Simple reflex
The pupillary light reflex is control by what autonomic nervous system?
pupillary light reflex is controlled by parasympathetic branch of Autonomous nervous system
