Sour Foods With Changes In Facial Expression.?
, why when we eat acidic food we reflexively wrinkle our faces? Please explain the process so that this can happen …
Reflex is the body's response to a stimulus (excitatory) that comes from inside or outside the body, the nature of the response is fast, brief, and unconscious. That is, when the body gets stimulated in any form, rapid responses can occur that occur outside our control. This reflex aims to protect the body against possible damage.
Reflexes are divided into primitive and acquired reflexes. Reflexes obtained are reflexes that occur due to our body studying an excitement that comes repeatedly. For example when someone sees the coming of the ball toward the face, then that person will avoid it automatically, because that person knows that when the face is hit by the ball, there will be pain.
The reflexes you are asking are included in the primitive reflex group. This means that the reflex occurs in humans without being studied. Primitive reflexes occur from birth. For example, the nipple sucking reflex in infants.
Reflexes result from the role of the reflex center in the spinal cord. Involves the role of sensory, motor and interneuron nerves. If you want to learn the physiological and molecular mechanisms, please refer to the physiology or neurology textbook.
