What else can I help you with?
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.
What type of homeostasis feedback reflex is the withdrawal reflex?
The withdrawal reflex is a negative feedback reflex that helps the body protect itself from harm. When the body comes into contact with a harmful stimulus, such as touching something hot, the withdrawal reflex causes muscles to contract and move the body part away from the stimulus, which helps to prevent injury.
What part in pupil reflex of coordinator?
The pupil reflex, specifically the pupillary light reflex, involves coordination between the optic nerve (cranial nerve II) and the oculomotor nerve (cranial nerve III). When light is shone in one eye, the optic nerve transmits signals to the brain, which then sends motor signals through the oculomotor nerve to constrict the pupil of both the illuminated eye and the other eye (consensual reflex). This reflex helps regulate the amount of light entering the eye and protects the retina from excessive illumination.
What part of brain controls pupil dilation?
Edinger-Westphal nucleus of the brainstem controls the pupil reflex. An ER doctor who looks at the response to a pen light is checking on brain stem activity.
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.
Does A Reflex causes a Stimulus?
No, a reflex is a rapid, involuntary response to a stimulus. The stimulus is what triggers the reflex reaction in the body.
What structure detects the stimulus in the reflex action?
The stimulus is detected by temperature or pain receptors in the skin. These generate impulses in sensory neurons. The impulses enter the CNS ( Central nervous system ) through a part of the spinal nerve called the Dorsal root.
What is the term for the reflex that protects the eye from too much direct light that might damage the retina?
The term is "pupillary light reflex." This reflex causes the pupil to constrict in response to a bright light stimulus, which helps protect the retina from excessive light exposure.
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.
What is the term for an involuntary reaction to an external stimulus?
The term for an involuntary reaction to an external stimulus is a reflex.
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 type of homeostasis feedback reflex is the withdrawal reflex?
The withdrawal reflex is a negative feedback reflex that helps the body protect itself from harm. When the body comes into contact with a harmful stimulus, such as touching something hot, the withdrawal reflex causes muscles to contract and move the body part away from the stimulus, which helps to prevent injury.
The simplest response to a stimulus is a what?
A reflex

How is the reflex response different from the sensory response?
The stimulus is what triggers the reflex response.
An in voluntary action under a stimulus?
A reflex
