Question

Give an example of unconditioned acquired reflex?

Answer 1

Reflexes can be either innate or acquired. The innate reflexes are genetically programmed and can be seen in every person’s body, independent of their cultural, socioeconomic, or neurophysiological distinctions. Innate reflexes evolve in a predictable order under normal circumstances, together with the neurosensorimotor and physiological maturation required to sustain their function.

Complete answer :
A reflex is an automatic, instantaneous movement that occurs in response to stimuli. The reflex is an involuntary response to a stimulus that occurs through a reflex arc and does not require or receive conscious cognition. Before an impulse reaches the brain, reflex arcs act on it.
A conditioned reflex is a taught response of a trained animal to a signal that has previously been associated with a significant event in the animal’s life.
An unconditioned acquired reflex is a natural, spontaneous response to unconditioned stimuli. Unconditioned acquired reflexes include knee-jerk, ankle reflex, and hand jerking back after contacting a hot plate, to name a few.
The biological role of unconditioned reflexes, which serve as the foundation for the rest of an organism’s neural activity, is to adjust an animal’s behavior to the regular, continuous conditions of its environment. The so-called conditioned reflexes, which are the dynamic interaction of unconditioned reflexes with acquired ones that develop over the course of an organism’s existence, which guarantees that the organism can adapt to changes in its internal and external settings.

Note :
It has been discovered that unconditioned reflexes undergo noticeable changes as a result of a variety of events (interaction with other reflexes, hormonal-humoral influences, and functional state of the organism and its central nervous system). Unconditioned reflexes "in pure form" may appear once or several times after the animal's birth, only to be "overgrown" by conditioned reflexes and additional unconditioned reflexes in a short period of time.
