The fine, down-like hairs on the newborn’s ears, shoulders, lower back, and/or forehead are known as.. Lanugo

The fine, down-like hairs on the newborn’s ears, shoulders, lower back, and/or forehead are known as:

• A- Vernix.
• B- Lanugo.
• C- Milia.
• D- Vibrissea.

Correct Response: B

The fine, soft hair found on a newborn’s body is referred to as lanugo.

Vernix is creamy substance that protects the skin, milia are the tiny white bumps found on the nose and cheeks, and vibrissea are the small hairs found in the nasal vestibule of the newborn.

The fine, down-like hairs on the newborn's ears, shoulders, lower back, and/or forehead are most likely: B. Lanugo.

Here's why:

- Vernix:

This is a waxy, white substance that coats the newborn's skin and protects it from the amniotic fluid. It's not hair-like and typically disappears within a few days after birth.

- Lanugo:

These are fine, downy hairs that can be present on a newborn anywhere on the body, including the ears, shoulders, lower back, and forehead. They are usually shed within the first few weeks of life.

- Milia:

These are tiny white bumps that can appear on a newborn's face, especially the nose and cheeks. They are not hair-related but rather clogged sebaceous glands, and they typically disappear on their own within a few weeks.

- Vibrissea:

These are stiff, whisker-like hairs around the nostrils and upper lip of some animals, including humans. They are not typically present on newborns.

Therefore, based on the location and description of the fine hairs, lanugo is the most fitting answer.
