Yes, the knee jerk reflex can be dampened or altered by distraction, as focus on other stimuli can reduce its intensity. However, the reflex itself is a deep spinal cord reflex that may still occur to some extent even with distraction.
A somatic reflex is where the body responds to stimulus. The message from the stimulus is sent through the central nervous system via the spine, and from there it travels to the brain.
Because reflexes only occur at the level of the spinal cord, not the brain.
The patellar reflex, also known as the knee-jerk reflex, doesn't occur when your leg is straight because the muscle involved in the reflex, the quadriceps, is relaxed when the leg is fully extended. The reflex response occurs when the muscle is slightly stretched, triggering a signal to the spinal cord that leads to the reflexive contraction of the quadriceps.
The no-reflex zone in the face refers to an area where certain reflexes, such as the corneal reflex or blink reflex, are absent or reduced. This can occur due to neurological conditions affecting the facial nerve or other related pathways. It is important to consult a healthcare professional for a thorough evaluation if you suspect any abnormalities in facial reflexes.
During the Achilles reflex test, you would expect to see plantar flexion of the foot, where the foot points downwards, in response to tapping the Achilles tendon. This reflex is a protective mechanism that helps maintain posture and balance in the lower extremities.
Actual reason is unknown, but conjecture is that it is an attempt to grab its mother as it begins to fall.
One important aspect of reflex action is to help protect us without having to think. Reflex actions are involuntary and quick. They are done to meet an emergency and occur at the level of the spinal cord. Examples include the gag reflex clearing unplanned foreign objects or your eyelid closing when something gets near your eye.

The gastroileal reflex inhibits gastric motility when the ileum becomes overdistended. This reflex ensures that the stomach doesn't empty too quickly into an already overfull small intestine, allowing for proper digestion and absorption to occur.
