ViviIn a fetus, the facial area is relatively large compared to the cranium. This is because the brain grows at a slower rate compared to the facial features in the early stages of development. As the fetus grows, the cranium eventually catches up in size to accommodate the growing brain.

What does it mean when the elderly begin to sleep in a fetal position?
Sleeping in a fetal position could indicate a need for comfort and security, as it mimics the position we were in before birth. It may be a response to physical discomfort or a way to alleviate joint pain in older age. However, if there is a sudden change in sleeping position, it's advisable to consult a healthcare professional to rule out any underlying health issues.
What does fgr mean?
"FGR" can stand for different things depending on the context. It could mean "Fetal Growth Restriction" in a medical setting or "Facility Goods Receipt" in a logistics context.
Do fingerprints change as we grow older?
Fingerprints do not change as we grow older. They are formed during fetal development and remain the same throughout our lifetime due to the unique pattern of ridges and valleys on our skin.
Whats more difficult-hand transplant or face transplant?
Both hand transplantation and face transplantation are highly complex procedures, and the difficulty can vary depending on the specific case. Hand transplantation requires intricate microvascular surgery and precise nerve and tendon repairs, while face transplantation involves more extensive reconstruction of multiple tissue types, including blood vessels, nerves, muscles, and bones. Overall, face transplantation is considered more challenging due to the complexity of reconstructing the facial structures and achieving functional and aesthetic outcomes.
Why do young children have a faster pulse rate than adults?
The short answer:The elevated heart rate is required to support the baby's rapid growth.Some DetailFetal development is dependent upon adequate exchange of gases and nutrients within the placenta. FHR (fetal heart rate) is generally about twice as high as the typical adult resting heart rate in order to support the high nutrient and gas exchange levels as well as the disposal of metabolic waste required for proper fetal development. Typical FHR in a fetus of 20 weeks averages about 155 beats per minute, with the normal range falling between 120 and 180. By term that rate has decreased, averaging 140 within a typical range of 120 to 160. By contrast, a healthy adult typically has a resting heart rate of about 80.Unusually low FHR can cause fetal acidemia, fetal acidosis and other fetal acid-base physiological problems. These, in turn often result in impaired fetal metabolism and impaired development.Throughout a person's life, typical heart rate can be seen to closely parallel rate of growth, steadily declining with the decline of growth in the mid-teens:Fetal - 20 weeks - 120-180Fetal - term - 120-160Infancy - 120-16012-35 months - 80-1103-5 years - 70-1106-12 years - 65-11013-18 years - 60-9019-61 years - 60-100**Cardio-vascular diseases account for the increased heart rates of older individuals.
