Want this question answered?
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.
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.
It is then possible for the brain to modify or 'condition' some reflexes
yes it is considered as a superficial reflex
Somatic reflex

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.
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.

Muscles and glands are the possible effectors of a reflex arc
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.
181 degree
No, it is not.
yes
On the basis of the limited information provided, the only possible answer is a reflex angle.
of course
yes. if the reflex angle is 260 degrees, the other is 100 which is obtuse
