Visceral reflexes are involuntary, automatic responses of the internal organs to stimuli, crucial for maintaining homeostasis in the body. These reflexes involve complex neural pathways that include sensory receptors, afferent neurons, integration centers in the central nervous system, efferent neurons, and the target organs, primarily mediated by the autonomic nervous system.
The Palmar Grasp Reflex is an involuntary response observed in newborns and infants, where they automatically close their fingers around an object placed in their palm. This reflex is a primitive survival mechanism, indicating the development of the nervous system and typically fades by the age of six months as voluntary motor skills develop.
