Fine, soft hair

Can you be more specific? What distinguishes it from hair that might be called fine/soft on the adult head?

Can you be more specific? What distinguishes it from hair that might be called fine/soft on the adult head?

Lanugo describes the fine, soft hair on fetuses that usually sheds before birth but sometimes doesn't shed until after birth. After shedding, lanugo hair is replaced by fine, soft hair (described as vellus hair) that is thicker than the original lanugo; vellus hair covers most of the body, and during puberty some regions are replaced with terminal hair. Men develop more terminal hair than women during puberty, and women retain more of their vellus hair. The Wikipedia articles I've linked include much more information you may be interested in.

Correct bernard! Your turn

Shoot, I didn't realize I was posting in Question Marathons...

Choose four movements from different rows and briefly describe each.
Flexion and extension
Abduction and adduction
Pronation and supination
Elevation and depression
Protraction and retraction
Inversion and eversion
Dorsiflexion and plantar flexion

Answer (Click to Show Hidden Text)

Flexion and extension - flexion decreases the joint angle between body parts; extension increases the joint angle between body parts
Abduction and adduction - abduction moves a body part away from the midline, while adduction moves a body part toward the midline
Dorsiflexion and plantar flexion - dorsiflexion points the toes upward so that you are on your heels; plantar flexion points the toes downward so that you are on your toes
Elevation and depression - elevation is movement in a superior direction (shrugging your shoulders); depression is movement in an inferior direction
