Fundal height, or McDonald's rule, is a measure of the size of the uterus used to assess fetal growth and development during pregnancy. It is measured from the top of the mother's uterus to the top of the mother's pubic symphysis.
In obstetrics, a cephalic presentation or head presentation or head-first presentation is a situation at childbirth where the fetus is in a longitudinal lie and the head enters the pelvis first; the most common form of cephalic presentation is the vertex presentation, where the occiput is the leading part (the part that first enters the birth canal).

Presentation of twins in Der Rosengarten ("The Rose Garden"), a German standard medical text for midwives published in 1513. In obstetrics, the presentation of a fetus about to be born specifies which anatomical part of the fetus is leading, that is, is closest to the pelvic inlet of the birth canal.
Only a comparatively small part of the head at term is represented by the face. The rest of the head is composed of the firm skull, which is made up of two frontal, two parietal, and two temporal bones, along with the upper portion of the occipital bone and the wings of the sphenoid. These bones are separated by membranous spaces, or sutures.
[71] [72] The mother has regular assessments for uterine contraction and fundal height, [73] vaginal bleeding, heart rate and blood pressure, and temperature, for the first 24 hours after birth. Some women may experience an uncontrolled episode of shivering or postpartum chills following the birth.
The sperm plasma then fuses with the egg's plasma membrane and their nuclei fuse, triggering the sperm head to disconnect from its flagellum as the egg travels down the fallopian tube to reach the uterus. In vitro fertilization (IVF) is a process by which egg cells are fertilized by sperm outside the womb, in vitro.
The Egg Head arc in the One Piece anime will start in January.
The head makes up nearly half of the size of the fetus. [8] Breathing-like movements of the fetus are necessary for the stimulation of lung development , rather than for obtaining oxygen. [ 9 ] The heart, hands, feet, brain, and other organs are present, but are only at the beginning of development and have minimal operation.
