have no useful function.

Question 4 .A mother of a newborn tells her doctor, "When something touches my baby's cheek, she turns towards it and begins to suck." Her doctor should respond by saying:

Group of answer choices

"This is normal. It's called the sucking reflex."

"This is abnormal. Go get medical help."

"This is great! Your baby will be intellectually advanced."

"This is normal. It's called the rooting reflex."

Question 5 Which is a possible advantage of breast-feeding?

Group of answer choices

This activity makes new mothers slim.

Breast-feeding helps promote mother–baby bonding time.

This activity decreases babies' immunities to disease.

Breast-feeding can lead to reduced myelin formation.

improve throughout childhood.

have no relationship to later social preferences.

not really that important.

a basic need.

Question 11. A baby's temperament is:

Group of answer choices

due to poor mothering.

based on the environment.

biological or inborn.

due to poor feeding.

Answer 1

1) Answer is Dendrites

Neuron consist of Cell body ( Perikaryon ) and multiple branches from cell body known as Dendrities which act as sensory signals and Axon through which nerve Impulse travels .

2)Answer is Help neuron impulses flow quickly .

Normally nerve Impulse travels through axon which is myelinated .Nodes of Ranvier are present in between .Myelination help in conduction of impulse at a faster rate from one node of Ranvier to another by Process known as Saltatory conduction .

3)Newborn reflexes typically disappear as Cortex matures.

Primitive reflexes are primitive which are present when the child is born and it diappears around 6-9 months when frontal lobe develops

Others are incorrect --Reflexeas are present since birth ( Not developed after months )

They hav useful functions like sucking rooting reflexes .They are not under conscious control .

Answer 4)

This is normal Rooting reflex .

When the baby cheek is touched baby moves the neck and try localised the nipp*e and start swallowing movement .This is Rooting reflex .

Rooting v/s Swallowing relfex

Rooting helps to localised the nipp*e

Sucking helps to cause movements around the tongue and try to extract the milk from the nipple .

Answer 5) Breast-feeding helps promote mother–baby bonding time.

Bonding between baby and mother is good after breast feeding

Others are incorrect --

Explanatio--Breast feeding provide immunity to Baby and also increase in myelin formation .It won't make mother slim .

Answer 8)

Lift head ,Pivot upper body and Sit

Remember milestone is always from up to down side from head to legs

So first lifting head started at around 1 month and completed by 3 months

Pivoting upper body means rolling around 5-7 months

Sitting around 6 months with support and 8 months without support .

Answer 9)correct sequence --->cooing; babbling; holophrases; telegraphic speech

Cooing are musical sounds develops around 9 months

Babbling 4 months then holophrases and telegraphic speech .
