What does the enterogastric reflex accomplish?
the enterogastric reflex is actaully a trio of reflexes that inhibit the vagal nuclei in the medulla, inhibit local reflexes and activate the sympathetic fibres that cause the pyloric sphincter to tighten and prevents further chyme entry into the small intestine.
Can you willfully inhibit a stretch reflex?
The stretch reflex is a normal, automatic response of the body to a sudden stretch of a muscle, controlled by the spinal cord. While it can be modulated, inhibiting it will require overriding the spinal reflex arc, which can be challenging to do willfully without external intervention. Techniques such as relaxation exercises or gradual stretching may help reduce the intensity of the stretch reflex.
How do you know consciously what has happened in a reflex action?
In a reflex action, the body reacts automatically to a stimulus without involving conscious thought, as this process occurs in the spinal cord. However, the brain is still aware of the event once the reflex has taken place. This awareness typically comes after the action has occurred, allowing us to recognize and understand what happened. Essentially, while the reflex bypasses conscious control, the brain processes the experience afterward, enabling us to recall it.
What happens to the patellar reflex if jendrassik's manoeuvre is performed at tha same time when patella is struck?
The Jendrassik maneuver is a medical maneuver wherein the patient flexes both sets of fingers into a hook-like form and interlocks those sets of fingers together. The tendon below the patient's knee is then hit with a reflex hammer to elicit the patellar reflex. The elicited response is compared with the reflex result of the same action when the maneuver is not in use. Often a larger reflex response will be observed when the patient is occupied with the maneuver, as the maneuver may prevent the patient from consciously inhibiting or influencing his or her response to the hammer.
What are the disadvantages of reflex actions?
Reflex actions, while beneficial for quick responses, have several disadvantages. They can occur too rapidly, bypassing conscious thought, which may lead to inappropriate or harmful responses in complex situations. Additionally, reflexes can be less adaptable to changing circumstances, limiting an individual's ability to respond effectively in nuanced scenarios. Lastly, reliance on reflex actions may inhibit learning and the development of more deliberate, thoughtful reactions.
What is a difference between reflex and voluntary action?
The difference between reflex and voluntary action is that a reflex occurs naturally in response to some sort of stimulus and voluntary action is something that is consciously carried out. An example of a reflex action is gagging and an example of voluntary action is flinching when someone is going to hit you.
What is the difference between a reflex and a feedback mechanism?
The difference between a reflex and a feedback mechanism is that the former is done without action by the brain but the latter is consciously done with feedback from the brain. A reflex is the reaction to external stimuli. Feedback to the brain can be given due to external or internal (within the body) reason.
What are the effectors of a reflex arc?
Muscles and glands are the possible effectors of a reflex arc
Which reflex would be most likely to inhibit the performance of a forward roll?
The reflex most likely to inhibit the performance of a forward roll is the stretch reflex, specifically the muscle spindle reflex. When the muscles involved in the roll, such as the neck, back, and abdominal muscles, are stretched beyond their normal range, the muscle spindle receptors send signals to the spinal cord to contract the muscles to prevent injury. This contraction can create resistance and hinder the smooth execution of the forward roll. Additionally, the protective withdrawal reflex may also play a role in inhibiting movement if the body senses potential danger during the roll.

What is the smallest reflex angle possible?
181 degree
Is it possible to draw Pentagon with 5 reflex angles?
No, it is not.

Which term does not belong predictable response voluntary act involuntary act or reflex?
Reflex does not belong because it is an involuntary act, while the other terms - predictable response, voluntary act, and involuntary act - all suggest some level of consciously initiated action.
Is the corneal reflex a somatic reflex or an autonomic reflex?
This particular reflex is autonomic as the affected muscle, constrictor pupillae muscle, is a smooth muscle and not under conscious control. Typically if you can consciously contract the muscle, any reflex associated with that muscle is somatic in nature.
