Lanugo is fine unpigmented hair that begins to grow on the babe from the 4th or fifth month of pregnancy (i).
It's the first hair that grows from the follicles. It grows everywhere on your baby, except for the palms, lips, and soles of the feet.
Premature babies tend to have more than lanugo when they're born. Although some full-term babies still accept some left by the time they're born, most really shed this hair inside the womb before the eighth calendar month.
The lanugo begins to abound on the scalp, where it spreads down the confront, around the eyebrows, nose, and forehead. It and so continues down the baby's torso, until it reaches the feet.
When it begins to shed inside the uterus, the hair incorporates into the amniotic fluid.

When the lanugo sheds, two types of hair replace it: vellus (fine hair) and last (thick hair). Final hair is what we accept on our scalp, arms, and legs.
What's the Purpose of Lanugo?
Lanugo serves a great purpose inside the uterus. Information technology helps the cheese-like substance, called vernix, to adhere to the infant's peel by interim as a physical anchor.
This, in turn, helps the vernix fulfill its purpose of keeping the baby'due south skin protected from the amniotic fluid.

The lanugo hairs ship vibrations through the vernix every time your baby moves. When these reach the amniotic fluid, they activate sensory receptors that connect to the nerve endings. These will ultimately end up stimulating your baby'due south growth.
One time it gets closer to the concluding month, the lanugo hair sheds. The stimulation will stop, and the growth rate slows downward.

Lanugo pilus can occasionally regrow in older children or adults. However, this is a bigger mystery and might be a sign of a more than serious wellness event.
When lanugo regrows on adults, it'south often confused with the thin vellus hair. Still, ane way to check this is by examining the overall health of the person, likewise as the location of the hair. If it grows in new places, for case, the confront or hands, it's probable to be lanugo.
A Patch of Hair Near the Spine
Some mothers may notice that their newborn has a patch of hair well-nigh the spine, on the lower back. This is not lanugo hair and is caused by something completely different.

Spina bifida is a congenital disability that affects the spine. It occurs when the baby's backbone doesn't develop properly. This may lead to a damaged spinal cord and nearby fretfulness, causing different disabilities.
The proper name spina bifida means "open up" or "split up" spine since sometimes this condition can cause an opening in the back.

The severity of this condition varies profoundly. Balmy versions of this defect may only crusade small-scale problems if any at all. However, severe cases can lead to weakness, loss of bladder control, or even paralysis.
2. Spina Bifida Occulta
Children born with a mild version, called spina bifida occulta, may sometimes have it without even knowing. In Latin, "occulta" ways hidden, and information technology basically means that the defect sits under the pare.
Yet, this type does go out ane clue on the lower office of the spine. Sometimes it's a birthmark or a dimple, or a patch of pilus. An ultrasound of the spine can diagnose this condition.
When looking from the inside, the spinal cord is likely attached to the tissue every bit opposed to being afloat in the spinal column. This may or may not cause any issues for the infant. Fortunately, almost babies with this condition won't experience any long-term problems.
three. Causes of Spina Bifida
Spina bifida generally occurs when your body doesn't accept enough folic acid during the commencement month of pregnancy. Folic acid is vital for tissue germination, cell growth, and evolution.
Low levels of this vitamin, both before pregnancy and in the early on weeks, will increment the hazard of spina bifida, and other neural tube defects.
Sometimes information technology nevertheless occurs, even though the female parent has a sufficient amount of the vitamin, although this is rare. In these cases, doctors doubtable it could be a genetic defect.
