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 is a example of reacting to a stimulus?
An example of reacting to a stimulus is pulling your hand away when you touch something hot. The sensory input of feeling the heat triggers a reflex that causes you to quickly move your hand to avoid injury.
What are the first and last elements in a spinal reflex?
The first element in a spinal reflex is the sensory receptor, which detects a stimulus. The last element is the effector, which carries out a response to the stimulus.
What is the first event associated with a reflex?
The first event associated with a reflex is the stimulus, which activates sensory receptors in the body. These receptors then send a signal to the spinal cord, bypassing the brain to produce a quick response from motor neurons, resulting in the reflex action.

What part of in pupil reflex for stimulus?
The stimulus in the pupil reflex would be light
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 is the term for an involuntary reaction to an external stimulus?
The term for an involuntary reaction to an external stimulus is a reflex.
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.
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.
An in voluntary action under a stimulus?
A reflex
How do you call an automatic reaction to a stimulus?
"reflex"
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 is a pathological response?
A pathological reflex is an unexpected/abnormal response to stimulus. For instance, a positive babinski reflex is a pathological reflex.
What is a example of reacting to a stimulus?
An example of reacting to a stimulus is pulling your hand away when you touch something hot. The sensory input of feeling the heat triggers a reflex that causes you to quickly move your hand to avoid injury.
