What part of in pupil reflex for stimulus?
The stimulus in the pupil reflex would be light
What are the example of reflex action?
When something like a hot object touches your hand, your receptors send impulses down the sensory neurone which then takes the impulses to the relay neurone (co-ordinator) which then sends the impulses to the motor neurone which goes in the opposite direction to an effector organ. This then reflexes your hand away from the hot object.
What does the ciliospinal reflex do to the pupil of the eye?
The pupil dilates when stimulated by the pinching on the nape of the neck.
Which cranial nerve in responsible for the reflex constriction of the pupil in response to light and accomodation?
The oculomotor nerve (cranial nerve III) is responsible for the reflex constriction of the pupil in response to light and accommodation.
How is pupil reflex controlled?
The pupil reflex is controlled by the autonomic nervous system, specifically the parasympathetic and sympathetic divisions. Constriction of the pupil (miosis) is controlled by the parasympathetic system through the action of the cranial nerve III (oculomotor nerve). Dilation of the pupil (mydriasis) is controlled by the sympathetic system through the action of the superior cervical ganglion.
Example of reflex action?
reacting when someone flashes his or her hand to your face that includes blinking-------------------------------------------------------A reflex action is a sudden reaction to a stimuli (a change in the environment) & often acts to protect you.Some are controlled by the brain (cranial reflexes) such as when you blink as dust lands in your eye, or your pupil gets smaller as light is shone in your eye.Some reflexes are controlled by the spinal cord (spinal reflexes) such as when you touch a hot object or stand on a pin.Some reflexes can have learnt responses so they are calledconditioned reflexes. These reflexes occur without you even thinking about them e.g. walking & producing saliva when you smell food.

What is cranial reflex?
A cranial reflex is a fast, involuntary response to a stimulus. It uses the brain stem as an integrating center (the brain receives sensory information and generates a response). This is contrasted to a spinal reflex, when the response is generated in the spinal cord itself, and the brain only finds out a reflex has occurred after the fact.An example of a cranial reflex would be the tracking movements of your eyes as you are reading this sentence. The dilation and contraction of your pupils in response to different levels of light is another cranial reflex.--------------An example of a spinal reflex would be standing on a pin or touching a hot object.
What an example of a reflex action?
One example of a reflex is when your leg jerks after a doctor hits it with a hammer.-------------------------------------------A reflex action is a sudden reaction to a stimuli (a change in the environment) & often acts to protect you.Some are controlled by the brain (cranial reflexes) such as when you blink as dust lands in your eye, or your pupil gets smaller as light is shone in your eye.Some reflexes are controlled by the spinal cord (spinal reflexes) such as when you touch a hot object or stand on a pin.Some reflexes can have learnt responses so they are called conditioned reflexes.

What reflex is centered in the brain and involves cranial nerves?
The reflex that is centered in the brain and involves cranial nerves is the cranial reflex. An example of this is the pupillary light reflex, where light exposure causes the pupils to constrict. This reflex involves the optic nerve (Cranial Nerve II) for sensing light and the oculomotor nerve (Cranial Nerve III) for pupil constriction. The processing occurs in the brainstem, illustrating the integration of sensory and motor functions.
What does the ciliospinal reflex do to the pupil of the eye?
The pupil dilates when stimulated by the pinching on the nape of the neck.
Is a pupil autonomic reflex?
yes
What is the consensual reflex of the pupil?
The consensual reflex of the pupil is the simultaneous constriction of the pupil in both eyes when light is shone into one eye. This reflex is controlled by the autonomic nervous system to regulate the amount of light entering the eye and protect the retina.
What reflexes classified as somatic reflexes?
Somatic reflexes involve the contraction of skeletal muscles in response to stimuli. Examples include the stretch reflex, withdrawal reflex, and crossed extensor reflex. These reflexes are typically controlled by the central nervous system and help protect the body from harm or maintain posture and balance.
When is a person considered dead?
Someone is considered dead when one cannot breathe without assistance, has no coughing or gagging reflex, has no pupil response to light, has no blinking reflex when the cornea is touched, has no grimace reflex when the head is rotated or ears are flushed with ice water, and has no response to pain.
Which cranial nerve in responsible for the reflex constriction of the pupil in response to light and accomodation?
The oculomotor nerve (cranial nerve III) is responsible for the reflex constriction of the pupil in response to light and accommodation.
