Question

Describe some of the newborn reflexes. How might they promote survival?

Short answer

Newborn reflexes are automatic responses present from birth such as the rooting reflex, suck reflex and Moro reflex. They promote survival by facilitating feeding (rooting and suck reflex) and responding to potential threats (Moro reflex).

Step-by-step solution

Explain What Newborn Reflexes Are

Newborn reflexes, also known as primitive reflexes, are automatic responses or actions that are present from birth. This means that the baby will produce these responses without thinking, they are instinctive reactions.

Describe Some Newborn Reflexes

There are several types of newborn reflexes such as: (1) Rooting Reflex, which is where if you stroke a baby’s cheek, it will turn its head in that direction and open its mouth. (2) Suck Reflex, which sees the baby commence a sucking motion if something is put into their mouth. (3) Moro Reflex (Startle Reflex), is a reaction to a loud sound or sudden movement. The baby extends its arms, legs, and fingers and arches its back.

Describe How Reflexes Promote Survival

These reflexes are considered survival instincts. For example, the Rooting Reflex is important for feeding. It helps the baby locate the source of milk or food. The Suck Reflex also aids in nutrition, allowing the baby to consume food. The Moro Reflex is often seen as a baby's primitive fight/flight response and is usually present for the first two to five months of a newborn's life. It prepares the baby for the sudden sensation of falling.
