Why do snakes have pelvic bones?
Snakes have pelvic bones as remnants of their evolutionary history when their ancestors had hind limbs. These pelvic bones have been greatly reduced in size and are not functional for walking or supporting legs, but they still play a role in supporting reproductive organs.
Why are pelvic bones of animals smaller?
Humans have to carry all of their weight upright and on just two legs. Animals that have four legs to support their weight and their pelvic bones are less massive. We "pay" for this as we are more prone to fractures and other problems of the upper leg bones. See link for more information:
When does the uterus return to the pelvic cavity after birth?
The uterus typically returns to the pelvic cavity within about six weeks after giving birth. This process is known as involution, during which the uterus gradually shrinks back to its pre-pregnancy size. Factors like breastfeeding and individual variations can influence the timing of this process.
During pregnancy which of the mothers body cavities increases most in size?
During pregnancy, the abdomen (abdominal cavity) increases most in size as the uterus expands to accommodate the growing fetus. This expansion allows for the growth and development of the baby throughout the pregnancy.
Why does a cell stay the same size in an isotonic solution?
In an isotonic solution, the concentration of solutes outside the cell is the same as inside the cell. This means there is no net movement of water in or out of the cell, resulting in a balanced state where the cell size remains constant.
Why is the pelvic girdle in snake is a vestigial?
The pelvic girdle in snakes is vestigial because they have lost their hind limbs during evolution. Since snakes no longer have hind limbs, the pelvic girdle serves no functional purpose and is reduced in size and structure.
How does the pelvic girdle size of fish compare to those of land animals?
Fish do not have "pelvic girdles" per se. Land animals in large majority have skeletal structures in their hips known as pelvic bones. In humans, men have a narrow pelvic size and women have a wider pelvic size. This is because women bear babies. The circular shape of these pelvic bones are referred to as the "pelvic girdle". Fish, however, don't have hip bones. Living in the water has eliminated the need for the extra physical support those bones would give during pregnancy. Since fish range in size from near-microscopic up to the immense whale shark, the equivalent to the pelvic area would vary greatly in size. Mammals too, range widely in size so comparison is difficult without a more specific question.
Is the pelvic girdle massive?
The pelvic girdle is not considered massive in terms of size or weight compared to other skeletal structures, but it is robust and sturdy. It consists of the ilium, ischium, and pubis, which form a strong bony ring that supports the weight of the upper body and allows for bipedal locomotion. Its strength is essential for bearing stresses during activities such as walking, running, and lifting. Overall, while it is designed for durability rather than mass, its structural integrity is vital for mobility and stability.
Is big buttock woman easier to give birth?
It is not necessarily easier for a woman with large buttocks to give birth. Sometimes the size of the pelvis is not related to the size of the buttocks and it is actually the pelvic area that impedes the birth process.

What is the size of a 4.50 carat diamond in millimeters?

What does the pelvic ultrasound reveal about internal organs?
A pelvic ultrasound can provide information about the uterus, ovaries, and surrounding structures. It can help identify abnormalities such as fibroids, cysts, or other structural issues in the pelvic region. Additionally, it can be used to evaluate the size, shape, and position of the organs and help diagnose conditions like endometriosis or pelvic inflammatory disease.
What is a girdle?
A sports girdle is an article of clothing worn under a uniform that has pockets for pads. Girdles are worn by football players and have pockets for hip, tailbone, and thigh pads.

How do you measure stomach to calculate how much weeks pregnant?
Difficult to do, as different women start 'showing' at different times. Some women don't begin showing their pregant size until well into their third trimester, others start getting fat at only 4 months. It all depends upon the individual's pelvic girdle size- it's best to rely upon other factors such as hormone levels, ultrasound scans, and other similar medical analyses- 'tummy size' is no guide!!
