What polysynaptic reflexes have a neuron?
The withdrawal reflex is an example of a polysynaptic reflex involving multiple neurons. This reflex pathway consists of sensory neurons carrying the stimulus information to the spinal cord, interneurons within the spinal cord processing the information, and motor neurons sending signals to muscles to initiate a response, such as withdrawing from a painful stimulus.
What type of reflexes are not subject to conscious control?
Involuntary reflexes, such as the knee-jerk reflex or pupillary reflex, are not subject to conscious control. These automatic responses are typically controlled by the spinal cord or brainstem without involvement of higher brain regions.
What does it mean if you have no reflexes in your legs?
The absence of reflexes in your legs could indicate nerve damage, spinal cord injury, or a neurological disorder. It is important to consult a healthcare professional for a proper diagnosis and treatment.
What are the qualities that unite somatic reflexes?
Somatic reflexes are involuntary responses to stimuli that involve skeletal muscles. They are quick, stereotypical, and require the involvement of the spinal cord or brainstem. These reflexes help maintain posture, protect the body, and allow for quick responses to potential danger.
How does the cerebral cortex overrides the reflex?
The cerebral cortex can not over ride reflexes. Reflex are mediated at the level of the spinal cord.
Why reflexes are quickly?
reflexes work very quickly, this is because your brain and spinal cord are processing data and information.
Where does the processing of most stimuli typically occur?
the brain <><><><><> Also, reflexes are processed in the spinal cord.
Where does processing of most stimuli typically occur?

What cord mediated reflexes?
The knee and elbow reflexes
Do reflexes occur in the spinal cord?
the spinal cords role in reflexes is to help you move about when it is needed when reacting to a stimuli
Do reflexes always involve the spinal cord?
Yes, the spinal cord controls ALL of your reflexes!
Spinal reflexes are produced in what?
Introduction. Spinal cord reflexes are simple behaviors produced by central nervous system (CNS) pathways that lie entirely within the spinal cord. The sensory afferent fibers that evoke these reflexes enter the spinal cord and activate spinal motor neurons directly or through a chain of one or more spinal interneurons
What responsible for autonomic reflexes?
spinal cord
If someone has a severed spine reflex still occurs?
Yes. Even though the spinal cord is severed, all the reflexes still work both above and below the severed spinal cord.
What is the homeostatic value of flexor reflexes?
Reflexes help to maintain homeostasis by permitting the body to make exceedingly rapid adjustments to homeostatic imbalances (The Spinal Cord and Spinal Nerves).
The simplest reflexes are mediated at the level of the?
spinal cord
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. These reflexes occur without you even thinking about them e.g. walking & producing saliva when you smell food.
