Rooting and sucking reflexes
Their are 4 types of reflexes:spinal reflex (knee jerk);cranial reflex (reading);somatic reflexes (involve contraction of skeletal muscles);autonomic (visceral) reflexes (involve responses of smooth muscle, cardiac muscle and glands)
sucking reflex
open the mouth in search of a nipple when touched on the cheek.
Newborn babies are born with the instinct to suck. It is often called a reflex because when you place something close to their lips, they will begin to seek out that thing. It is also called a rooting reflex. In infants that are born early many do not have this reflex yet. It is a way of the infant to find a nipple.
Make sure you are comfortable and that the baby is well positioned. If he is newborn, using conveniently placed pillows may help. Dip a facecloth into cold water and rub the nipple on the breast that you are going to offer first, until the nipple stands up.Then, hold the nipple between your fingers and make it into a biscuit shape. Now you need to stimulate the baby's rooting reflex by stroking his cheek gently with the nipple. He will turn towards the nipple and try to latch on.Don't touch his other cheek with your finger, because he will become confused and turn his head from left to right in a frantic attempt to find the nipple and the mother may think he is refusing the breast, when actually the very opposite is happening. He must have the rooting reflex stimulated on ONLY one cheek at a time.Don't try to put the nipple straight in his mouth, because he won't take it that way. Nature has put the rooting reflex in the cheek.
wel al i know is: putting fingers in there mouth and when you put your finger in there hand it is their reflex to close their hand. this isn't a reflex to newborns but one of a young babies reflex is when a person walks up to them they put their hands up

The value of a reflex action is to survive. For example, if we place our hands on a hot oven. Our reflex would be to take our hand off and register the pain. OR A perfect example would be the rooting reflex. Which helps a breastfed infant find the mother's nipple. Babies display it only when hungry and touched by another person, not when they touch themselves.
For a number of reasons, the main one being the "cold crying" and "cold presser" reflex. Also, it's the newborns way of clearing any remaing amniotic fluid from their lungs.
spinal reflex
No, a somatic reflex are the reflexes of the skeletal muscle movements. The gag reflex is considered to be an autonomic reflex.
knee jerk aka patellar reflex is an example of a stretch reflex
