maternities
The first greenish-black stool of the newborn, composed of cellular debris, bile, lanugo, and vernix caseosa.
meconium
Onset of menstruation
menarche
Protrusion of the meninges and spinal cord through a defect (spina bifida) in the vertebral arches of the spine
meningomyelocele
Tiny white papules on the nose due to retention of secretions in sebaceous glands, which disappear in the first weeks after birth
milia
Spontaneous loss of pregnancy from the time of conception until 24 weeks gestation.
miscarriage
all the products of conception have been passed without the need for medical or surgical intervention
complete miscarriage
some, but not all, of the products of conception have been passed; retained products may be part of the fetus, placenta or membranes
incomplete miscarriage
the cervical os is open, but the products of conception have not been expelled
inevitable miscarriage
ultrasound evidence of fetal demise but no uterine activity to expel the products
missed miscarriage
vaginal bleeding before 24 weeks gestation, viable pregnancy on ultrasound
threatened miscarriage
a spontaneous miscarriage that is complicated by intrauterine infection

Hypertrophied sebaceous glands, which appear as lumps scattered throughout the areola surrounding the nipple
montgomery follicles
The mulberry-like mass of cells formed by repeated divisions of the fertilized ovum
