Reflexes are involuntary and nearly instantaneous movements in response to a stimulus or trigger. In humans‚ there are different types of reflexes. These are stretch reflexes‚ cranial nerve reflexes‚ primitive reflexes‚ and cranial nervous system reflexes. Stretch reflexes‚ which are often called deep tendon reflexes‚ provide information on the integrity of the central nervous system and peripheral nervous system. Generally‚ decreased reflexes indicate a peripheral problem‚ while lively

Infant Reflexes Rooting Reflex Rooting reflex is present at birth and assists in breastfeeding. However‚ this reflex will disappear at around four months. An infant will turn his head toward anything that touches his cheeks or mouth. He will search for the objects by turning his head and opening his mouth to follow the ‘root’. This reflex helps the infant search for the breast or bottle to start feeding. Moro Reflex The Moro reflex is present at birth and disappears in about two months of

Classifications of reflexes A) Primitive reflexes and genetic sub-programs 1. Reflex responses to light touch: Light touch produces a variety of reflex responses‚ depending upon the area stimulated and the age of the individual. The motor responses are most marked in the early months of life. Grasp reflex (palmar and plantar): Light touch of the palm or sole produces reflex flexion of the fingers or toes. The most effective way to elicit the reflex is to
